本文介绍了永磁同步电动机磁芯磁各向异性引起的齿槽转矩。采用二维磁化特性法和常规方法两种建模方法，采用有限元法计算磁各向异性引起的齿槽转矩。结果表明，由于磁各向异性的影响，并联层压铁芯永磁电机与旋转层压铁芯永磁电机的齿槽转矩波形不同。在高磁通密度区域，不同的建模方法会产生不同的齿槽转矩幅值。
This paper describes the cogging torque of the permanent magnet synchronous (PM) motors due to the magnetic anisotropy of motor core. The cogging torque due to the magnetic anisotropy is calculated by the finite element method using two kinds of modeling methods: one is the 2D magnetization property method, and the other is the conventional method. As a result, the PM motors with parallel laminated core show different cogging torque waveform from the PM motors with the rotational laminated core due to the influence of the magnetic anisotropy. The amplitudes of the cogging torque are different depending on the modeling methods in the region of high flux density.
