Selection and analysis of slot number of stator and rotor for small five phase squirrel cage induction motor

Abstract

Compared with the traditional three-phase induction motor, the five phase induction motor has the advantages of low torque ripple amplitude, high ripple frequency, high power density, good fault-tolerant performance. It is widely used in the driving and propulsion fields of electric vehicles, rail transit, ships, etc., and also in some special small power transmission mechanisms with high fault-tolerant performance requirements. In this paper, the main parameters of a small five phase induction motor are calculated based on the magnetic circuit method and the winding function method. At the same time, the number of stator and rotor slots in the small five phase induction motor is calculated and simulated. It is concluded that the stator 40 slots and the rotor 26 slots can be used as the optimization of the small five phase motor.
