According to the analysis of the American market, in each luxury car, 59 permanent magnet motors are needed, and 20-30 in general cars. On the other hand, energy conservation in automobiles is getting more and more attention. Hyundai automobiles require motors to improve performance and efficiency, and use flat disk structures to reduce space, increase output, eliminate spark interference, reduce noise, extend life, and facilitate centralized control. This is the specialty of high speed brushless motor. It is expected that the brushed DC motors used in automobiles will be replaced by permanent magnet high speed brushless motors.

Application of high speed brushless motor in the automotive industry


In electric vehicles, electric motorcycles, electric bicycles and other vehicles, the high speed brushless motor will be the main driving motor. Among the electric vehicles for environmental protection, the permanent magnet high speed brushless motor is the most developed traction drive motor. In the future, the built-in permanent magnet brushless motor is also called hybrid permanent magnet reluctance motor. This motor superimposes reluctance torque on the basis of permanent magnet torque. The existence of reluctance torque helps to improve the motor The overload capacity and power density, and it is easy to weaken the speed control, expand the constant power range operation, suitable for the high-efficiency, high-density, wide-speed traction drive motor of electric vehicles, they have been designed in new models of Japanese and American major automobile companies Adopted in.
