Rotor Design and Optimization of the Single-phase Line-start Synchronous Reluctance Motor

摘要

The single-phase line-start synchronous reluctance motor (LSSynRM) is suitable for household appliances, but an optimized design of rotor, crucially influences the performance of motor, is hard to obtain. This paper optimizes the rotor design of LSSynRM to make a higher saliency ratio with the trade-off between saliency ratio and synchronizing ability. The mechanical-field-circuit coupled Finite element (FE) simulation is employed. The simulation turns out the improvement of motor efficiency by the presented optimization. The performance of the LSSynRM and IPM is also compared.
