Comparative analysis of surface mounted and interior permanent magnet synchronous motor for low rating power application

Abstract

In this paper a comparative analysis is reported between Surface Mounted Permanent Magnet (SMPM) and Interior Permanent Magnet (IPM) Synchronous Motor for low Power rating application using ANSYS Software. In this study, a 0.55Kw, 220V rated Permanent Magnet Synchronous Motor (PMSM) with two different structures is considered. Here both electromagnetic (i.e. Air gap magnetic flux density) and electromechanical properties (i.e. torque) are considered for obtaining the target. In addition, Iron loss and is also involved for comparison. The results of the analysis were confirmed by Finite Element (FE) Analysis and were based on a simplified analytical model based on a given rating. Results obtained through this method, for validated with the result reported in the literature. Further modification is also done in the parameters and those results are also reported.
