Comparison and Performance Analysis of IPM, SynRM and Flux-intensifying IPM Machines

Interior permanent magnet motors (IPM) provide many different advantages over other electric motor types in torque quality, reliability and efficiency. The reluctance torque is an important contribution to improve torque density and flux weakening capability in IPM machines. So, considering geometric design characteristics to enhance reluctance torque in IPM machines can be helpful to have a better performance. Introducing flux barriers into the rotor can increase the saliency ratio and the reluctance torque. This also leads to enhancement of the overall performance of the machine. This paper is aimed at comparing and analyzing the capabilities for synRM machine, IPM machine and flux-intensifying IPM machine with different structures. Finally Different electromagnetic characteristics of the three machines are simulated in FEM 2D and the results are analyzed, studied, and compared.
