摘　　要：针对球磨机用无齿轮直驱环形永磁同步电机具有较大的直径与长度比、多对磁极和转速低的特点,介绍了一种分体式定子机座的结构设计方法。首先,依据设计方案推算出机座的主要结构尺寸;然后,使用Creo Parametric软件,在保证整体结构刚度和强度的前提下,建立机座在承受固定载荷下的参数化几何模型;最后,借助Ansys Workbench有限元分析软件对机座进行数值模拟分析,验证设计方案的可行性和合理性。Aiming at the characteristics of the gearless circular permanent magnet synchronous motor used in ball mill such as the large diameter to length ratio,multiple pole pairs and low speed,a kind of split-type stator frame structural design method is introduced.Firstly,the main structural dimensions of the motor frame are calculated based on the design scheme.Secondly,on the premise of ensuring the rigidity and strength of the overall structure,a parametric geometric model of the frame under fixed load is established by using the Creo Parametric software.Finally,the design is verified for feasibility and rationality through numerical simulation analysis by means of the Ansys Workbench finite element analysis software.
