Recent studies show that line start permanent magnet assistance synchronous reluctance (LS-PMA-SynRMs) present promising technologies because of their advantages such as simple structure and minimized amount of permanent magnet. Moreover, the LS-PMA-SynRMs can operate with direct start for net voltage or drive by power converter with torque control methods. Especially, the LS-PMA-SynRM has higher irreversible demagnetization level than IPM because it has less permanent magnet in rotor slots. This paper will develop different rotor designing and modeling of a line-start permanent magnet assistance synchronous reluctance motor (LS-PMA-SynRM) with permanent magnets arrangement in I-W-U type using both industrial and EV applications. The dynamic speed and torque performances are analyzed and compared by finite element analysis FEA. The performance of LS-PMA-SynRM is analyzed considering the position and I-W-U shape of its permanent magnet, as well as its manufacture. The proposal model of LS-PMA-SynRM has been improved efficiency, torque, and output power. Finally, the LS-PMA-SynRM with U layered magnets rotor is prototyped to verify by full efficiency map to evaluate EVs application.
