Abstract

This paper deals with the design characteristics of Permanent Magnet assisted Synchronous Reluctance Motor (PMa-SynRM) adopting ferrite magnets and stator skew structure, which has been purposely developed for EV (Electric Vehicle) propulsion. Not only numerically identified design characteristics such as torque production and ripples, back-EMF waveform, magnetic losses and efficiency, but mechanical stress and demagnetization of ferrite magnets have been investigated in detail. Furthermore validity, of the designed PMa-SynRM has been verified by running performance compared with Interior buried Permanent Magnet Synchronous Motor (IPMSM) based on Finite Element Analysis (FEA).
