摘要：

The paper presents a study of a Permanent Magnet Synchronous Motor (PMSM) with 10 poles and 12 slots having different permanent magnet configurations. Bread loaf surface mounted magnets, radially embedded in the rotor, internal magnets, or Halbach magnets distribution were modeled with the professional software COMSOL Multiphysics. The influence of the different motor topologies upon the shape of the motor phase and line-to-line back EMF and load voltages, as well as on the torque ripple and cogging torque amplitude is analyzed. The Finite Element Method (FEM) quasi-stationary models were coupled with the stator circuit equations to simulate the sinusoidal current supply of the motor. The results are mainly qualitative, the purpose is to assist in motor design strategy and show some of the complexity of the choices in such a process.
