Abstract

The utility model discloses a novel reduction dual-stator permanent-magnet motor. The motor mainly comprises an external stator assembly, a rotor and internal stator assembly, a rear terminal cover and a front cover assembly, wherein the external stator assembly is connected with the front cover assembly and the rear terminal cover by screw bolts, and a sun gear of the rotor and internal stator assembly is engaged with a planetary gear of the front cover assembly. A planetary gear reduction mechanism is adopted, so that the overall dimension of the motor is smaller than the conventional permanent-magnet motor, saving the steel material, copper material, rare earth material, and permanent-magnet material and reducing the cost of the motor; and the output torque of the motor is increased. According to the utility model, if the stator coil of the motor is energized, the rotor rotates, and the rotation speed and the torque is transmitted from the sun gear of the rotor to an output shaft through the planetary gear reduction mechanism, thereby driving the vehicle to move. The motor is suitable for hybrid electric vehicles.
