Multi-objective optimization design of a PM-less synchronous motor using simplified response surface method


For cost-effective concern, how to reduce the usage amount of the rare-earth permanent-magnet (NdFeB) in an IPMSM has become an important research issue. Fortunately, the less permanent-magnet synchronous motor (PM-Less SM) with confusing rotor flux barriers and clever permanent-magnet arrangement has the potential to become high-performance motor. The main… (More)
