Abstract

This paper presents the characteristic analysis of thermal behavior of a single-phase line-start permanent magnet motor(LSPM) for high-efficiency design. By analyzing of thermal behavior, it can consider demagnetization characteristics of permanent magnets. In addition, by calculating the allowable current density it will be able to reduce the size of the stator. For this reason single-phase LSPM is necessary to examine the thermal analysis. Thermal analysis was performed using heat source mapping, and it is verified by finite element method.
