4KW 5KW 6KW Brushless Permanent Magnet DC motor for vehicles 48V 72V 96V 144V

The drive collects information of motor rotor position timely ,the phase is changed according to the motor rotor position. The motor stator windings give current to produce positive torque which make the motor run. The speed-control signals change the duty cycle of the power device. So the current changes, the motor torque changes, and the motor speed changes. 

1, Motors have special dual-stator structure, constituting automatic variable torque system with the special drives. Corresponding to the vehicle’s conditions like climbing, starting low speed and high speed,the system automatically work in single-stator or dual-stator state. Motor gives appropriate torque to make the dynamic performance adjust to the requirement. No longer need gearbox, avoid high current discharging, save energy, improve the travel distance, extend battery life.
2, Brushless motor with No spark, No carbon brush,Compact structure, High overload ability, Long service life. 
3, Motor rotor with rare-earth permanent magnetic field,self-excitation, saving energy, good effect with generating ,,Energy feedback and Electric braking.

4, Outstanding load characteristics,good peformance with low speed,high starting torque,small starting current, preventing high current discharging of the battery, corresponding to the discharging characteristics of the battery,adapting to the needs of vehicle frequent startup. The battery life can be extended by 50%,The driving distance can be prolonged about 30% ~ 50% when charged.

5, Equipped with branded excellent special motor driver.
6, Operating highly efficiently in the whole speed range 

7, Motors and drives are cooled by air or water. Low temperature. Free maintenance,High reliability, Long life.
