Design of Small Five Phase Induction Motor and Slot Number Selection

The primary design of a small five phase induction motor was carried out based on the magnetic circuit method.The slot type of the motor was optimized by Ansoft software,and the method of calculating its inductance parameters by winding function method was introduced.The selection of slot number of stator and rotor in the small five phase induction motor was screened and analyzed.For the motor with 20 slots,30 slots,40 slots in the stator and 26 slots in the rotors simulation was cunducted.The simulation analysis verified the rationality of the design.From the comparative analysis of the simulation of starting speed,stator current and radial air gap magnetic density,the conclusion is that the stator of 40 slots can be used as the small five phase motor with 26 slots of rotor.
