Abstract: For improving torque density, speed range for constant power operation and overload capacity of the interior permanent magnet synchronous machine (IPMSM) with single-layer PMs, a type of IPMSM with double-layer PMs is designed and analyzed in this paper. Under the same stator structure, winding type and the volume of PMs, the models of IPMSM with single and double-layer PMs are built respectively. The electromagnetic properties including torque, inductance, loss and efficiency are calculated and compared for the two types of IPMSM by FEA. The results show that the salient rate, output torque, the area with high efficiency and speed range for constant power with double-layer PMs are improved efficiently compared to the IPMSM with single-layer PMs.
Keywords: Permanent magnet synchronous motor, single and double layer permanent magnet, electromagnetic properties, finite element analysis
