Abstract

The permanent magnet synchronous reluctance machine (PMSynRM) is a type of permanent magnet synchronous machine (PMSM) with the objective to provide high reluctance torque. This is realized by a particularly designed constellation of flux barriers in the rotor of the machine. Beside high efficiency and supplied power density, an acoustic evaluation of this machine is performed for various applications, for example in hybrid and electric vehicles (HEV, EV). A study for the acoustic design of a PMSynRM is presented in this paper. An approach to improve the magnetic circuit by varying the shape of the flux barriers is introduced. Using numerical simulations every operating point in the d-q-diagram is considered. The local force density in the air gap of the machine is calculated and analyzed with a 2-D Fourier Transformation. The results are used as analysis criterion.

永磁同步磁阻电机。改善声学性能的设计指南
永磁同步磁阻电机(PMSynRM)是一种以提供高磁阻转矩为目标的永磁同步电机。这是通过在机器转子中特别设计的磁通屏障星座来实现的。除了高效率和提供的功率密度外,还对该机器进行了各种应用的声学评估,例如混合动力和电动汽车(HEV, EV)。本文对PMSynRM的声学设计进行了研究。介绍了一种通过改变磁阻的形状来改善磁路的方法。通过数值模拟,考虑了d-q图中的每个工作点。用二维傅里叶变换计算和分析了机床气隙中的局部力密度。结果作为分析标准。
