this axle fit motor from 3kw to 5kw.

 The products are mainly used in electric cars, electric golf carts, electric tour buses, electric hunting vehicles, heavy-duty electric trucks and other electric vehicles.
First, the main drive motor
The main drive motor with three-phase AC squirrel cage induction motor. The motor uses a special the electromagnetic structure optimization design, fully enclosed aluminum housing, with a wide speed range, high efficiency, peak power, strong overload capacity, more stable and reliable performance, compact structure, small and light, maintenance-free characteristics. The motor base speed following the cross-torque operation, constant power operation above base speed to meet electric vehicles start, acceleration, climbing, frequent starts and other requirements. High-speed operation can produce a large torque, the electric vehicle having a good performance at high speeds. In downhill braking energy feedback to charge the battery, thereby extending the operation of the vehicle mileage.
