Electromagnetic Design and Analysis of Permanent Magnet-Assisted Synchronous Reluctance Motor

To improve the electromagnetic performance of a three-phase synchronous reluctance motor (SynRM), a 4-pole, 36-slot permanent magnet-assisted synchronous reluctance motor is designed in this paper by embedding a permanent magnet in its rotor reluctance(PMaSynRM). The motor's no-load performance and load performance are analyzed by electromagnetic simulation using the finite element method. Finally, for the motor's output torque pulsation, reverse potential harmonics, two schemes, stator slant slot, and stator side open auxiliary slot optimization, are used to optimize the motor, which reduces the motor's reverse potential harmonics and torque pulsation.
