Electric motors technology enabling profound improvements on electric vehicles performance

Aviation accounts for 2% of global carbon emissions, with more than half of that contributed by international flights. In 2018, aviation contributed 2.4% of human-generated CO2 emissions worldwide. The need to reduce gas emissions, optimize aircraft performance, decrease operating and maintenance costs, is pushing the aircraft industry to progress towards more electric aircraft (MEA), and ultimately an All-Electric Aircraft. Electric plane power is much simpler — batteries power an electric motor that spins a propeller.

 

For example, Airbus has been developing its ZEROe concept aircraft, which will be the world’s first zero-emission commercial aircraft when it is released in 2035.  Similarly Rising fuel prices across the globe are impelling people to shift to non-conventional fuel alternatives. As a result, electric vehicles are manufactured with a view of reducing operational costs and carbon footprint. The core element of the EV, apart from Electric Vehicle Batteries, which replaces the Internal Combustion engines is an Electric motor. When compared with common internal combustion engines (ICEs), electric motors are lightweight, physically smaller, provide more power output, are mechanically simpler and cheaper to build, while providing instant and consistent torque at any speed, with more responsiveness, higher overall efficiency, and lower heat generation.

 

The use of electric power in airframe systems saves fuel and helps in cost reduction. Electric motors can be made quite light and small and still develop considerable power with high reliability—they scale well. Electric motors have few components, are relatively easy to maintain, and battery ranges have improved significantly. However, electric motors are not as convenient or common as ICEs in mobile applications (i.e. cars and buses) as they require a large and expensive battery, while ICEs require a relatively small fuel tank.

 

In a new whitepaper in march 2021 , “Achieving the Paris Agreement: The Vital Role of High-Efficiency Motors and Drives in Reducing Energy Consumption”, ABB revealed potential for energy efficiency improvements in industry and infrastructure enabled by the latest motors and variable speed drives. ABB says its calling on governments and industry to accelerate adoption of the technology to help combat climate change as they can reduce global electricity consumption by 10 per cent. According to the International Energy Agency (IEA), industry accounts for 37% of global energy use and some 30% of global energy is consumed in buildings.

 

While mostly hidden from public view, electric motors — and the variable speed drives which optimize its operation — are embedded in almost every built environment. They power a vast range of applications, from industrial pumps, fans and conveyors for manufacturing and propulsion systems for transportation, to compressors for electrical appliances and heating, ventilation and air conditioning systems in buildings.

 

Motor and drive technologies have seen advancement in the past decade, with today’s designs delivering energy efficiencies. However, a significant number of industrial electric motor-driven systems in operation today — in the region of 300 million globally — are reportedly inefficient or consume much more power than required, resulting in energy waste. Independent research estimates that if these systems were replaced with optimized, high-efficiency equipment, the gains could reduce global electricity consumption by up to 10%. In turn, this would account for more than 40% of the reduction in greenhouse gas emissions needed to meet the 2040 climate goals established by the Paris Agreement.

 

Airbus has also been collaborating with Rolls-Royce to co-develop E-FanX, their hybrid aircraft that will be driven by a 2-megawatt electric motor. Aviation high-speed motor systems are set to play a central role in providing the necessary propulsion power to these electric-based airplanes due to their reliability and ability to work in conjunction with electrical units.

 

Motor principle

An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor’s magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor’s shaft.

 

Electric Motors construction, types, classification and working principle | Car Construction

Electric motors can be powered by direct current (DC) sources, such as from batteries, or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy.

 

Electric motors produce linear or rotary force (torque) intended to propel some external mechanism, such as a fan or an elevator. An electric motor is generally designed for continuous rotation, or for linear movement over a significant distance compared to its size. Magnetic solenoids produce significant mechanical force, but over an operating distance comparable to their size.

 

 

Motor technologies

Electrification of Aircrafts, vehicles etc. is based on three main pillars: batteries, electric motor and the powertronics [the power management system]. The rapid development in the field of Power electronics and control techniques has created a space for various types of electric motors to be used in Electric Vehicles. The electric motors used for automotive applications should have characteristics like high starting torque, high power density, good efficiency, etc.

 

Traditionally DC motors, have been prominent in EV propulsion. Their control principle is simple. However, the principle problem of DC motors arises from their commutators  and  brushes, which makes  them less  reliable  and  unsuitable  for maintenance-free operation. Recent technological developments have  pushed AC motors to a new era, leading to take definite advantages over DC motors: higher efficiency, higher power  density,  lower  cost, more reliable, and almost maintenance free. As high reliability and maintenance-free operation are prime considerations in EV propulsion, AC induction motors are becoming attractive.

 

Conventional linear control such as PID  can no longer satisfy  the  stringent  requirements  placed  on  high- performance EVs. In recent  years, many  modern control strategies,  such  as  model-referencing  adaptive control  (MRAC),  self-tuning  control  (STC),  variable  structure control  (VSC), fuzzy control and neural  network control (NNC), have been proposed. Both MRAC and STC have been applied to EV propulsion. In order to implement the aforementioned modem control  strategies, powerful microelectronic devices are  necessary.

 

“The power of a motor goes up with its speed. What you want to do is spin it as fast as possible in order to make it as small as possible – but then you get into problems of cooling,” says Ian Foley, managing director of British motor manufacturer Equipmake. “The limitation now on how you improve the performance of electric motors, is how effectively you can get the heat out of them.”

 

Equipmake’s solution is to rearrange the motor’s magnets so that they’re positioned like the spokes of a wheel. This not only increases torque (the force which causes rotation), says Mr Foley, but also makes the magnets more accessible, so that cooling water can be run directly over them. The company is also now using additive manufacturing – 3D printing – to improve cooling and also cut costs. “There are two main benefits we’ll get from additive manufacturing. One is that you can integrate multiple components, so you end up with a much lower component count because things that would previously have been bolted together are all in one piece,” says Mr Foley.

 

“The other main thing is the issue of cooling. “In order to cool you need much more effective heat exchanges, and with additive manufacturing you can effectively increase the surface area inside the motor for the cooling surfaces and therefore get much greater cooling potential.”

 

For selecting the appropriate electric vehicle motors, one has to first list down the requirements of the performance that the vehicle has to meet, the operating conditions and the cost associated with it. For example, go-kart vehicle and two-wheeler applications which requires less performance (mostly less than 3 kW) at a low cost, it is good to go with BLDC Hub motors. For three-wheelers and two-wheelers, it is also good to choose BLDC motors with or without an external gear system. For high power applications like performance two-wheelers, cars, buses, trucks the ideal motor choice would be PMSM or Induction motors. Once the synchronous reluctance motor and switched reluctance motor are made cost effective as PMSM or Induction motors, then one can have more options of motor types for electric vehicle application.

 

 

Electric Motor types

Electric motors may be classified by considerations such as power source type, internal construction, application and type of motion output. In addition to AC versus DC types, motors may be brushed or brushless, may be of various phase (see single-phase, two-phase, or three-phase), and may be either air-cooled or liquid-cooled. General-purpose motors with standard dimensions and characteristics provide convenient mechanical power for industrial use. The largest electric motors are used for ship propulsion, pipeline compression and pumped-storage applications with ratings reaching 100 megawatts. Electric motors are found in industrial fans, blowers and pumps, machine tools, household appliances, power tools and disk drives. Small motors may be found in electric watches. In certain applications, such as in regenerative braking with traction motors, electric motors can be used in reverse as generators to recover energy that might otherwise be lost as heat and friction.

 

DC Series Motor

High starting torque capability of the DC Series motor makes it a suitable option for traction application. It was the most widely used motor for traction application in the early 1900s. The advantages of this motor are easy speed control and it can also withstand a sudden increase in load. All these characteristics make it an ideal traction motor. The main drawback of DC series motor is high maintenance due to brushes and commutators. These motors are used in Indian railways. This motor comes under the category of DC brushed motors.

 

Brushless DC Motors

It is similar to DC motors with Permanent Magnets. It is called brushless because it does not have the commutator and brush arrangement. The commutation is done electronically in this motor because of this BLDC motors are maintenance free. BLDC motors have traction characteristics like high starting torque, high efficiency around 95-98%, etc. BLDC motors are suitable for high power density design approach. The BLDC motors are the most preferred motors for the electric vehicle application due to its traction characteristics.

 

Permanent Magnet Synchronous Motor (PMSM)

Long used in servo motor applications, Permanent Magnet Synchronous Motors (PM) are gaining increased use in industrial motor driven systems. The PM motor technology replaces the aluminum bars in the rotor with powerful permanent magnets created using rare earth elements; these are either surface mounted (SPM) or internally mounted (IPM).

 

This motor is also similar to BLDC motor which has permanent magnets on the rotor. Similar to BLDC motors these motors also have traction characteristics like high power density and high efficiency. The difference is that PMSM has sinusoidal back EMF whereas BLDC has trapezoidal back EMF.

 

Permanent Magnet Synchronous motors are available for higher power ratings. PMSM is the best choice for high performance applications like cars, buses. Despite the high cost, PMSM is providing stiff competition to induction motors due to increased efficiency than the latter. Motor manufacturers have demonstrated that permanent magnet designs offer efficiency gains as high as three NEMA bands higher (1.5 – 2%) than a Premium Efficient AC induction motor. However, in most cases these gains cannot be achieved without pairing the PM motor with a variable speed drive (VSD).

 

PMSM is also costlier than BLDC motors. Most of the automotive manufacturers use PMSM motors for their hybrid and electric vehicles. For example, Toyota Prius, Chevrolet Bolt EV, Ford Focus Electric, zero motorcycles S/SR, Nissan Leaf, Hinda Accord, BMW i3, etc use PMSM motor for propulsion.

 

Three Phase AC Induction Motors

The induction motors do not have a high starting toque like DC series motors under fixed voltage and fixed frequency operation. But this characteristic can be altered by using various control techniques like FOC or v/f methods. By using these control methods, the maximum torque is made available at the starting of the motor which is suitable for traction application. Squirrel cage induction motors have a long life due to less maintenance. Induction motors can be designed up to an efficiency of 92-95%. The drawback of an induction motor is that it requires complex inverter circuit and control of the motor is difficult.

 

Tesla Model S is the best example to prove the high performance capability of induction motors compared to its counterparts. By opting for induction motors, Tesla might have wanted to eliminate the dependency on permanent magnets. Even Mahindra Reva e2o uses a three phase induction motor for its propulsion. Major automotive manufacturers like TATA motors have planned to use Induction motors in their cars and buses. The two-wheeler manufacturer TVS motors will be launching an electric scooter which uses induction motor for its propulsion. Induction motors are the preferred choice for performance oriented electric vehicles due to its cheap cost. The other advantage is that it can withstand rugged environmental conditions. Due to these advantages, the Indian railways has started replacing its DC motors with AC induction motors.

 

Switched Reluctance Motors (SRM)

A switched reluctance motor (SRM) is a brushless DC electric motor that provides continuous torque. The SRM electronic drive is characterized (paired) to the motor; together, they form a very capable, closely matched system. The SRM is a viable replacement and improvement to induction motors in variable speed applications.

 

Switched Reluctance Motors is a category of variable reluctance motor with double saliency. Switched Reluctance motors are simple in construction and robust. The rotor of the SRM is a piece of laminated steel with no windings or permanent magnets on it. This makes the inertia of the rotor less which helps in high acceleration. The robust nature of SRM makes it suitable for the high speed application. SRM also offers high power density which are some required characteristics of Electric Vehicles. Since the heat generated is mostly confined to the stator, it is easier to cool the motor.

 

The biggest drawback of the SRM is the complexity in control and increase in the switching circuit. It also has some noise issues. Once SRM enters the commercial market, it can replace the PMSM and Induction motors in the future.

 

Copper Rotor Motors

The innovation of the copper rotor motor technology was born out of the need to meet the low voltage motor market demands for greater energy efficiency; a demand not met by the traditional die cast aluminum rotor design. John Caroff, Marketing Manager, Low-Voltage Motors, Siemens Industry, Inc., Norwood, Ohio, stated that, “The goal was to gain efficiency using new copper rotor technology but retain the same footprint as the traditional aluminum rotor design; this is important, not only for new applications, but also for retrofit applications.

 

By using the copper rotor in our IEC motors we not only achieved the new efficiency requirements in Europe (IE 2, IE3) and USA (MG1 Table 12-12), but we were also able to reduce, in many cases, the length of the motor, making it more compact, and in others, achieving higher horsepower, both in the same footprint.”

 

In addition to standard induction motor applications, the CRM drives electric vehicles, from sport cars to military vehicles such as the 300 horsepower 100-pound engine in the Tesla Roadster, to the multiple CRMs used in the design of the US Army’s HEMITT A3 heavy expanded mobility tactical truck.

 

H3X is a startup that aims to accelerate that future with a reimagined, completely integrated electric motor that it claims outperforms everything on the market.

The energy required to propel an aircraft fast enough to generate lift grows exponentially as the size and mass of the plane increase. A handful of kilowatt-hours will serve for a drone, and a few EV-scale batteries will work for a light aircraft, but beyond that the energy required to take flight requires batteries the bulk and weight of which make flight impractical.

 

And there are two general avenues for improvement: better batteries or better motors. So either you can fit more energy in the same mass or use what energy you have more efficiently. Both are being pursued by many companies, but H3X claims to have made a huge leap forward in power density that could unlock new industries overnight. While even an improvement of 10% or 20% in power per kilogram (e.g., a 50-pound motor putting out 120 horsepower rather than 100) would be notable, H3X says its motor is performing at around 300% of the competition’s output.

 

While the pieces are similar in some ways to motors and power assemblies out there now, the team basically started from scratch with the idea of maximizing efficiency and minimizing size. Electric motors generally have three main sections: the motor itself, a power delivery system and a gearbox, each of which may have its own housing and be sold and mounted separately from one another. One reason why these aren’t all one big machine is temperature: The parts and coolant systems of the gearbox, for instance, might not be able to operate at the temperatures generated by the motor or the power system, or vice versa. Put them together and one may cause the other to seize up or otherwise fail. The different sections just have different requirements, which seems natural.

 

H3X challenges this paradigm with a novel integrated design, combining advances in materials, manufacturing and electric components so that they act synergistically, each enabling the other to be used to best effect.  “All the components are all intimately connected to the same housing and motor. We’re making a truly integrated design that’s one of the first of its kind at this power level.”

 

For instance, recently improved power switching hardware can be run at hotter temperatures and handle higher loads — this raises performance but also allows for shared cooling infrastructure. The shared infrastructure can itself be improved by using new pure-copper 3D-printing techniques, which allow more cooling to fit inside the housing. Using 3D printing means custom internal geometries so that the motor, gearbox and power delivery can all be mounted in optimal positions to one another instead of bolted on where existing methods allow.

 

The result is an all-in-one motor, the HPDM-250, that’s smaller than a lot of the competition, yet produces far more power. The best production motors out there are around 3-4 kilowatts per kilogram of continuous power. H3X’s prototype produces 13 — coincidentally, just above the theoretical power density that would enable midrange passenger aircraft.

 

There is the risk that stacking cutting-edge techniques like this makes the cost rise faster than the performance. Liben said that while it’s definitely more expensive in some ways, the smaller size and integrated design also lead to new savings in cost, time or material. “People think, ‘3D-printing copper, that’s expensive!’ But when you compare it to the super high-performance windings you’d need otherwise, and the different ways that you manufacture them, that can require a lot of manual steps and people involved … it can be a lot simpler printing something,” he explained. “It can be counterintuitive, but at least from my BOM [bill of materials] cost, when you’re selling something three times smaller than the other guy, even if it’s high-performance materials, it’s actually not as expensive as you’d think.

 

Servicing a fully integrated motor is also fundamentally more complex than doing so for an off-the-shelf one, but Liben noted that they were careful to think about maintenance from the start — and also that, while it may be a little harder to service their motor than an ordinary electric one, it’s much, much simpler than servicing even the most reliable and well-known gas-powered motors.

 

Despite the huge gains H3X claims, the target market of passenger aircraft is hardly one that they, or anyone, can just jump into. Heavily regulated industries like air travel require years of work and technology proving to change a fastener style, let alone the method of propulsion. So H3X is focusing on the numerous smaller, less regulated industries that could use vastly improved electric propulsion. Cargo drones, electric boats and air taxis might still be rare sights on this planet, but a big bump to motor power and efficiency might be what helps tip them from niche (or vaporware) to mainstream. Certainly all three of those applications could benefit hugely from improved range or payload capacity.

 

Market

The electric motor market is expected to grow from an estimated USD 113.3 billion in 2020 to USD 169.1 billion by 2026, at a CAGR of 6.9% during the forecast period. The  use of electrical equipment and machines in different industries and the renewables sector are major factors driving growth in the electric motor market. Rapid technological advancements have been playing an imperative role in the growth of the market. Further, improved insulation and operational efficiency have significantly improved the electro-mechanical machines in terms of safety and functionalities, leading to increased demand across multiple industries. Electric motors are used in multiple applications across industry verticals such as home appliances, industrial machinery, and vehicles. The market is expected to witness high growth from Heating, Ventilation, and Cooling (HVAC) applications as they are an inseparable component of HVAC equipment.

 

COVID-19 Impact on the Global Electric Motor Market

The most significant near-term impact on electric motors that are already contracted or in the manufacturing process will be felt through supply chains. Industry executives are anticipating delivery and construction slowdowns, either because nations have shuttered industries to slow the spread of coronavirus or because the workers have tested positive. Many components and parts for manufacturing electric motors come from China, the US and some parts of Europe. Manufacturing disruptions in China and the US could contribute to a significant fall in the electric motor market over the next one or two years.

Due to the COVID-19 pandemic, local currencies of many countries have depreciated. There is misalignment of supply and demand, leading to financial losses for components/parts manufacturers. Key components used in manufacturing electric motors are typically procured in US dollars, which results in increased component cost

 

Electric Motor Market Dynamics

Driver: Increased demand for HVAC systems in residential, commercial, and industrial end-users

Heating, ventilation, and air conditioning (HVAC) systems provide thermal comfort and ensure the air quality in indoor spaces. They are one of the core building blocks of modern infrastructures, especially for large office buildings or shopping malls. Electric DC motors are widely used in HVAC systems to achieve high efficiency in airflow systems and maximize their life and power. The demand for HVAC systems is increasing in Asia Pacific, especially in China and India, owing to the continuous growth in their industrial and commercial sectors. According to a report by Timetric Construction Intelligence Center (CIC), a market intelligence company, ~USD 1.08 trillion is expected to be invested in the global construction sector, especially for the development of industrial buildings during the next four to five years

 

Restraints: Fluctuating prices of raw materials from China

The prices of raw materials such as permanent magnets, steel bars, copper wires, and precision thin metals such as specialty alloys, which are used to make electric motors, are controlled by a few manufacturers in China. There is not much product differentiation and the price of the product determines the dominance of certain suppliers in the market. The resulting price fluctuations have to be borne by the other manufacturers/suppliers in the market. For instance, when manufacturers and suppliers face fluctuations in the prices of rare-earth permanent magnets during the manufacturing processes, they are unable to pass the price change to end-use customers. Hence, the profit margins of raw material suppliers are negatively affected.

 

Opportunities: Transition of global automotive industry toward electric vehicles

The global automotive industry is transitioning toward electric mobility with significant changes in electric vehicle technology. In Europe, the proactive measures taken for the decarbonization of society are leading to the increased adoption of electrical vehicles that use electric motors. Advancements in battery technologies have lowered battery costs and improved their charging speed. Increasing government support in the form of tax redemptions and incentives to promote eco-friendly electric vehicles that use electric motors are also acting as opportunities for the growth of the electric motor market. According to IEA, China is expected to account for 50% of the global passenger electrical vehicles by 2025.

 

Challenges: Easy availability of low-quality and inexpensive electric motors

The electric motor market is highly fragmented, featuring a large number of local and international players. Product quality is a primary parameter for differentiation in this market. The organized sector in the market mainly targets industrial buyers and maintains excellent product quality, while the unorganized sector offers low-cost alternatives to tap local markets. Local manufacturers of electric motors in most countries target the unorganized sector and compete strongly with the global suppliers in the respective markets. Leading market players are currently exposed to intense competition from such unorganized players supplying inexpensive and low-quality electric motors. This acts as a key challenge for the growth of the market.

 

Motor type

Electric motors are of 3 types, namely AC, DC, and hermetic motor. Among these, the demand for AC motors has been the highest in the past, and the situation is likely to remain the same in the years to come as well. AC motors have higher speed and torque as compared to other variants and they are able to function at higher voltages. In addition this, AC motors are easier to maintain than DC and hermetic motors.

 

The AC motor type held the largest share in 2020. It is estimated to generate over USD 166 billion by 2028 due to the extensive use of AC motors in various applications ranging from irrigation pumps to modern-day robotics.

 

AC motors are further of two types, namely synchronous and induction, between which, a larger demand was created for induction AC motors in the past. Three-phase induction motors are highly popular in a number of industrial applications. Single-phase induction motors are utilized commonly in household applications, including grinders, pumps, mixers, fans, and washing machines. It is owing to such wide range of applications of induction motors that their demand is rising at a rapid pace.

 

 

By output power

The fractional horsepower (FHP) output segment represented over 87% of the overall market value in 2020. Fractional horsepower motors are used widely in all household appliances ranging from vacuum cleaners to coffee machines to refrigerators

 

The above 1 hp motors segment segment is expected to lead the electric motor market from 2020 to 2026. Electric motors are used in various end user applications owing to their compactness, light weight, and low maintenance requirements. The installation of electric motors in industrial and transportation end user applications is expected to show high growth.

 

Application  segment

The motor vehicles segment is the most prominent application segment, commanding more than 40.0% of the overall market value in 2020. The electro-mechanical machines are also extensively used in heavy industrial equipment as well as agricultural machinery

The industrial segment is expected to lead the electric motor market from 2020 to 2026. This sector provides good scope for motor manufacturers, as most industries depend on motorized automation. The segment includes the utilities, oil & gas, cement & manufacturing, metal and mining, oil & gas, renewables, petrochemicals & chemicals, water & wastewater, and paper & pulp industries, all of which use electric motors for pumps, boilers, compressors, and other applications, at various process stages.

 

By rotor type, the inner rotor segment is expected to be the largest contributor during the forecast period.

The inner rotor segment is estimated to grow at a faster rate from 2020 to 2026. In inner rotor type motors, rotors are positioned at the center and surrounded by stator winding. These motors are used in the manufacturing, automotive, and consumer electronics industries for robotics, CNC machines, automatic door openers, and metal cutting and forming machine applications. These applications require motors that can carry out fast acceleration and deceleration of speed, offer high starting torque, have reversible action capability, and are compact. According to the IEA, EV Outlook 2020, the global sales of electric cars reached 2 million in 2019, 40% higher than in 2018. This indicates the increased demand for electric vehicles and their accelerated manufacturing in coming years, which in turn, is expected to fuel the demand for inner rotor electric motors.

 

The motor vehicles segment is the most prominent application segment, commanding more than 40.0% of the overall market value in 2020. The electro-mechanical machines are also extensively used in heavy industrial equipment as well as agricultural machinery

Asia Pacific region held the largest revenue share in the electric motor market in 2020 and is projected to witness the fastest CAGR of 7.8% from 2021 to 2028. The growth can be attributed to increasing industrialization investments in countries such as China, India, South Korea, and Australia.

With the rapid industrialization, the countries in Asia Pacific are moving toward internet-based industrial operations in each sector. According to the GSM Association, the developed countries in Asia Pacific, such as South Korea, Japan, and Australia, are increasingly exploring the potential of innovative services and connected devices. The automotive sector in the region is also booming. Asia Pacific is the largest producer of automobiles in the world. In 2018, the region manufactured more than 50 million commercial vehicles. These factors are expected to drive the growth of the market in Asia Pacific

 

Further, the scope for market growth in the region is expected to increase significantly over the coming years, owing to the evolving agriculture sector through efficient irrigation practices and technology transfer.

 

Industry

The industry is characterized by regulatory policies and government initiatives that promote energy efficiency in machines and equipment.
