With the development of automotive intelligence, micro motors are widely used in various systems and components of automobiles/new energy vehicles to meet consumers' requirements for comfort. As a result, automotive motors will be thin and light, high efficiency, brushless and motor control DSP development.

1, thin and light short. The shape of the car motor is towards the flat, disc type, lightweight and short direction, in order to adapt to the needs of the specific environment of the car. In order to reduce the external dimensions, the first consideration is to use high-performance neodymium iron boron permanent magnet material. For example, the magnet weight of a 1000W ferrite starter is 220g, and with NdFeB magnets, it weighs only 68g. adopting the scheme of designing the starter motor and generator as one unit reduces the weight by half compared with the separated one. Domestically and internationally, permanent magnet DC motors with disc-type wire-wound rotors and printed-wound rotors have been developed, which can also be applied to the cooling and ventilation of engine water tanks and air-conditioner condensers. For example, Lifui's magnetic pump motor is a permanent magnet DC motor designed specifically for new energy vehicle battery cooling systems. Flat permanent magnet stepper motor can be used in automotive speedometer, price meter and other electronic equipment, recently, Japan has introduced ultra-thin centrifugal fan motor, the thickness of only 20mm, can be installed in the framework of the wall is very small in the occasion for ventilation and cooling.

2, high efficiency. For example, the wiper motor after the improvement of the reducer structure, greatly reducing the load on the motor bearings (reduced by 95%), volume reduction, weight reduction of 36%, the motor torque increased by 25%. At present, most automotive motors using ferrite magnets, with the neodymium iron boron magnets to improve the cost-effective, will replace the ferrite magnets, will certainly make the automotive micro-motor lighter, more efficient.

3, brushless. In accordance with the automotive control and drive automation and reduce the failure rate, eliminate radio interference and other requirements, in high-performance permanent magnet materials and power electronics technology, microelectronics technology under the auspices of a large number of automotive applications of various specifications of permanent magnet DC motors will be to the direction of brushless development.

4, motor control DSP. In the senior, luxury car in the engine control, automatic speed control, anti-skid brake control, steering control, vehicle float control, speed automatic conversion control system, are applied by the DSP control of the micro motor (some will be placed in the electronic control part of the motor end cap, so that the control unit and motor integration). By knowing how many micro motors a car is equipped with, you can observe the level of the car's configuration and the degree of comfort and luxury. In today's rapidly expanding demand for automobiles in this period, the application of automotive motors more and more widely, the entry of foreign capital also makes the micro-motor industry competition more and more intense, but these phenomena can be illustrated, the development of automotive motors is promising, micro-motor in the field of automotive electronics will also make a big difference.
