研究了V型分数槽集中绕组内置式永磁同步电机在压缩空气系统中的气隙形状。通过有限元分析（FEA），研究了空载气隙密度、平均转矩、转矩脉动和铁耗的谐波。结果表明，V型永磁同步电动机气隙整形可以有效地降低转矩脉动和定子铁心损耗。这是因为气隙磁通密度的低次谐波可以在平均转矩略有下降的情况下减少。所提出的气隙成形方法具有设计简单、制造简单的优点。最后，以一台气隙成形的V型永磁同步电动机为例，验证了分析结果的正确性。
The shaping of the air gap of a V-typed fractional slot concentrated windings interior permanent magnet synchronous machines (IPMSMs) is investigated for compressed-air system (CAS) applications in this article. The harmonics of no-load air gap density, average torque, torque ripple, and iron losses are studied by the finite element analysis (FEA). The results show that the air gap shaping of the V-typed IPMSM can be effectively used to reduce the torque ripple and stator core loss. It is because the low-order harmonics of the air gap flux density can be reduced with a little decrease in the average torque. The proposed air gap shaping methods have the advantages of simple design and simple manufacture. A V-typed IPMSM with air gap shaping is prototyped to verify the correctness of the analysis results.
