Abstract

An external rotation type vehicle drive motor comprises a motor stator (2) and a motor rotor (3). The motor stator is arranged on a vehicle shaft (1) in an axially movable manner. The motor rotor is arranged outside the motor stator, and can rotate around the motor stator. Therefore, in the vehicle drive motor, a conventional transmission system is omitted, and the power loss of the transmission system is also eliminated. A vent hole (4) is arranged on the motor stator of the vehicle drive motor, so that the vehicle drive motor has a self-cooling function and a conventional cooling system is omitted. In addition, stepless speed change is realized by controlling the power voltage and current, and a reverse pulse magnetic field is generated by inputting pulse current to realize braking; therefore, the energy utilization rate of the vehicle drive motor is high.
