3kw-150kw brushes and brushless sample: We have brush type sZYCD-100 (100KW) which has these characteristics about Vehicle Electric Motor:

Stator: combined permanent magnet and field winding together, and the field winding is in series with the rotor winding. When buses are going ascent or start, you can cut in the field winding when the rotor winding current is still the same, and the battery storage will keep the same time. And the controller matched with the motor is simpler and the price is about 1/3 of the controller in the brush motors. And the brush life is at least 150000 km. And it have been used in the 121 buses in Beijing and saved electricity about 30 %( the number is from Beijing Technology of Institute)

1. PMDC EV Motor specifications: rated voltage: 80v— 400v rated power: 2. 5kw— 100kw rated speed: 1600rpm— 400rmp rated efficiency: 92%--94% weight: 25kg— 560kg
