Abstract

This paper presents analysis and design methodology of single-phase line-start permanent magnet synchronous (LSPM) motors. The d-q axis inductances of LSPM motors have a nonlinear variation according to the current and the load angle. The variation of d-q axis inductances due to load angle is calculated by finite element method (FEM) in steady state. Iron loss is analyzed considering the harmonics of the flux density waveforms using iron loss curves. The validity of the presented analysis method considering the variation of the d-q axis inductances is verified by comparing with experimental results.
