Simulation and design of Motor-CAD based six-phase compatible permanent magnet synchronous motor
In order to examine the working performance of the six-phase permanent magnet synchronous motor,the structure and characteristics of the permanent magnet synchronous motor were analyzed,and the main parameters were determined such as the stator and rotor inner and outer diameter dimensions,air gap,slot type,axial length,and number of pole slots of the six-phase compatible permanent magnet synchronous motor through a large number of formula calculations.Based on Motor-CAD motor simulation software,the electromagnetic calculation of six-phase compatible permanent magnet synchronous motor was carried out to analyze the variation of motor torque pulsation and slot torque under different tooth width,slot fillet radius,number of slots,and permanent magnet arc length.Motor performance indexes such as torque pulsation,cogging torque,and maximum possible motor torque at a speed of 1 500 r/min were obtained,and the cooling design of the six-phase compatible permanent magnet synchronous motor was used to solve the temperature data of each part of the motor using the spiral water channel water cooling method.The design of the motor was found to meet the torque and temperature requirements through experiments.
