Design od 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-start permanent magnet motor (LSPM) are proposed. ill the design procedure, the permanent magnet is designed first and the windings and capacitors are designed later. As well, the points of design of each 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 400 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.
