[0002] At present, most of the production methods of the driving motor salient pole rotors used in electric vehicles adopt an integrated structure, such as the existing technology, patent name: brushless electromagnetic and permanent magnet hybrid voltage stabilizing power generation device for electric vehicle range extender, patent number: ZL201610.306601.4 discloses the following technical scheme, which consists of a front end cover, a rear end cover, a hybrid rotor, a stator, and an electronic voltage regulator controller. In the arc-shaped slot, the electric excitation winding is wound on the T-shaped salient pole. The motor rotor with this integrated structure limits the wire diameter and the number of winding turns of the excitation winding. It is difficult to wind the coil, the processing technology is complicated, and the cost of the motor is reduced. High, and the magnetic pole is provided by a single magnetic steel magnetic field, the performance of the motor is not stable enough
