| 摘 要： | 着重研究不同分段斜极段数对转矩波动和噪声的影响。通过Ansoft软件进行3D电磁场计算,并将3D场计算的气隙磁密进行矢量相加,利用Ansys软件将叠加后的平均气隙磁密进行2D声场计算,将分段斜极复杂的3D声场计算简单化,同时提出一种将转子分成两段斜极结构的简单工艺,并总结了满足该工艺的设计要求。通过试验验证,该仿真计算与试验基本一致,为该类电机设计计算提供参考。

| Abstract: | The study focued on the influence of different step numbers on torque ripple and noise of motor. Through the Ansoft to calculate 3D electromagnetic field, and add the air gap flux density vector by 3D electromagnetic field calculation, using Ansys. The average of the air gap flux density after superposition to calculate by 2D sound field. To simplify the complex rotor step skewing 3D sound field calculation. Besided a simple process that the rotor could be divided into two segments skewing structure were put forward, the requirements met the process of design also summarized. Through experimental verification the simulation calculation and test were basically identical. To provide a reference for this kind of motor design and calculation. |
