The permanent magnet motor has the advantages of simple structure, reliable operation, high power density, high efficiency, low noise and flexible motor structure form, and is widely researched and applied. With the successful development of the high-performance neodymium-iron-boron permanent magnet in the 80 s of the 19 th century, the more practical and novel advantages of the rare earth permanent magnet motor in a vehicle-mounted power supply system are shown. The permanent magnet synchronous motor can keep higher efficiency and power factor in a wider load range, has obvious energy-saving effect when in light-load operation, and has excellent application prospect.

The improvement of power density inevitably brings the reduction of heat radiating area, if the rotor loss is too high, then the permanent magnet easily produces irreversible demagnetization because of high temperature, influences the reliability of motor operation.
