A study on the design and the characteristics in single-phase line-start permanent magnet motor

The purpose of this paper is the optimal design of a single-phase LSPM (line-start permanent magnet motor). A single-phase LSPM has a permanent magnet in the rotor that is same as induction motor. For that reason, the transient characteristics are very different from an induction motor. Therefore, we need the PM design to consider transient and steady-state characteristics. In this paper, we designed a single- phase LSPM that has a high power and a good starting characteristic, and analyzed the performance of designed LSPM by varying each parameter. Finally, we examined and compared the simulation results and the prototype motor´s characteristics.
