Abstract

The invention discloses a direct current polyphase machine which comprises a silicon steel sheet laminated iron core and a plurality of groove teeth located on the periphery of the silicon steel sheet laminated iron core. A coil is wound on each groove tooth. The continuous groove teeth are wound by B, B1...Bx, A, A1...Ax, C, C1...Cx respectively in sequence so that 3*(x+1) phase coils are formed. (x+1) three phase systems which are mutually independent are formed by connection of the 3*(x+1) phase coils, so that (x+1) independent output ends are formed. Therefore, the efficiency of the direct current polyphase machine reaches over 95%, an overload coefficient of the direct current polyphase machine is increased to over 120% compared with that of a normal three-phase permanent magnet motor, fault-tolerant capability is improved x times, and the torque density of the direct current polyphase machine is (x+1) times of that of the normal three-phase permanent magnet motor.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a permanent magnet DC multi-phase motor. Background technique [0002] At present, with the development of electric vehicle technology, three-phase brushless DC motors have replaced brushed motors and have been widely used. Although the three-phase brushless motor technology has matured, the high-power motor has high requirements on the controller, and the commutation noise is large, and the positioning torque is large. Limited by the controller technology, the actual motor power is small, and it is mainly used on electric bicycles and some electric motorcycles. It is rarely used as a drive motor for electric vehicles. [0003] Moreover, the motor winding of a three-phase motor has only three phases. If one of the three phases is missing, the motor cannot run and the car cannot move. [0004] In view of this, it is necessary to provide a new DC motor to solve the above problems...
