Permanent Magnet Blushless DC motors

    

The EV car applies the original fuel car’s chassis, body shell and other necessary parts, it also replaces the original engine, oil box and fuel system by motor, accelerator, electrical supporting system and battery. By wiring to connect the motor, accelerator, electrical supporting system and battery together, a whole set of electrical system is formed. For simplicity and more effective speed regulation, usually maintain the original gear box and clutch, that is, the gear of the motor output shaft ratchets with the original gear box and clutch structure, forming an integrated motor drive structrure.

Motor is the heart of the EV car and its performance decides EV car’s acceleration function, start grade climbing load capacity and highest speed performance.

The development of motor goes through three stages. At the earliest it’s brush DC motor with good speed regulation function and cheap price, but as the brush is short-life and needs charge, it requires maintainence. As the development of electronics technology, people apply Frequency Control Asynchronous Squirrel-cage motor with long life because of without brush, but still its AC speed regulation function is not so good as DC motor. At last people invent DC brushless motor which with both DC motor’s good speed regulation function and AC motor’s long life.

Actually, these three motors are still under usage. 

M&C DC brushless motor not only maintains DC motor’s good speed regulation function, but also AC motor’s long-life function. It’s the best motor for EV car driving at present, and it’s power ranges from bicycle, tricycle, car and bus(250W ~200KW).
