Design of Single-Phase Line-Start Permanent Magnet Motor Using Equivalent Circuit Method

Abstract

- In this research, the design procedure and the design method of a single-phase line-startpermanent magnet motor (LSPM) are proposed. In the design procedure, the permanent magnet is design parameter are explained. In the design of the single-phase LSPM, the equivalent circuit method is combined with the finite element method (FEM) because it has a shorter analysis time than FEM. The 40 watts single-phase LSPM is designed and manufactured. The characteristics of the manufactured single-phase LSPM are analyzed and experimented. From the analysis result and the experiment result, it is verified that the design procedure and the design method of the single-phase LSPM is valid.
