Analysis and Design of Distributed and Concentrated IPMSM for Compressor in Electric Vehicles

According to the change of traction system from combustion engine to electric motor for electric vehicles, the compressor in air conditioner needs to be replaced to the separated system. This paper compares the performance of distributed and concentrated wound interior permanent magnet synchronous motor (IPMSM) for compressor. Each IPMSM model is analyzed by 2D FEA for cogging torque, output torque and back-EMF. Furthermore, the analysis of torque ripple characteristics, loss calculation and saliency ratio are performed.
