Magnetic and mechanical analysis of IPM synchronous motor: Design and construction

Abstract

In order to analyze and design the Interior Permanent Magnet Synchronous Motor (IPMSM), the parameters must be defined according to characteristics of the motor. To obtain a good motor, the decrease of leakage flux is done by reduction of mechanical stresses and increase of the magnetic flux density. The magnetic flux distribution in the air gap is first analyzed. Then, the rotor is designed by using a specific mathematical model. Two topologies based on placing of permanent magnet into the rotor, which is placing in parallel shape and V-shape, are analyzed and designed. The mechanical stresses and rotor strains occurring during the rotation at high speed are studied.
