Abstract

In recent years Line Start Permanent Magnet (LSPM) motor has attracted a lot of attention thanks to many advantages, such as high efficiency, high power factor, and high power density. In this motor, at the start, the risk of irreversible demagnetization in Permanent Magnet (PM) is essential due to the large inrush current. So in this paper using Finite Element Method (FEM) the effective factors on demagnetization of this motor structure at various temperatures will be investigated. In addition, the sensitivity analysis will be carried out. Finally, the electromagnetic torque of this motor using a modified FEM algorithm will be calculated and compared to the conventional FEM algorithm.
