Some Considerations on the Optimum Design of an IPMSM using a Bonded Rare-Earth Magnet

Abstract

In this study, we examined a method of directly molding a bounded magnet into a rotor core and the optimum magnet shape design of an interior permanent magnet synchronous motor (IPMSM). We realized the same size and torque as a conventional IPMSM using a sintered rare-earth magnet.
