A PM-Assisted Synchronous Reluctance Motor with Two Slot-Pitch Winding

This paper presents a novel electric motor solution to tackle the increasing demand on the traction motor for electric vehicles. The proposed electric motor has a 24 slots 10 poles fractional slot two-slot pitch winding and a PM-assisted synchronous reluctance (PMaSynR) rotor with arc-shaped barriers. First, the winding layout will be introduced. Then, a comparison with other winding layouts will be detailed. The benefits of the proposed solution including low torque ripple and high reluctance torque capability will be demonstrated. All this confirms that it is a good trade-off solution for traction application.
