LS-PMA-SynRMs can operate with a direct start for net voltage or drive-by power converter with torque control methods. Especially, the LS-PMA-SynRM has a higher irreversible demagnetization level than IPM because it has a less permanent magnet in rotor slots in comparison with IPM. This paper will develop different rotor designs and modeling of a line-start permanent magnet assistance synchronous reluctance motor (LS-PMA-SynRM) with permanent magnets arrangement in V type considering skew slot and demagnetization effect. The short circuit current is analyzed and compared by finite element analysis FEA in no skewed and skew slots. The demagnetization performance of LS-PMA-SynRM is analyzed considering V magnet shape and skewed angle. The proposed model of LS-PMA-SynRM has been improved efficiency, torque, and output power. Finally, the LS-PMA-SynRM with 3V layered magnets rotor is prototyped to verify by full efficiency map to evaluate EVs application.
