摘　　要：为提高液压注塑机的能源利用率，设计一款注塑机用永磁同步电动机，用于注塑机的伺服系统改造。结合注塑机的实际生产工况，确定了注塑机用永磁同步电动机的主要尺寸参数，并利用Ansys Maxwell 2D软件搭建有限元模型。文章侧重对槽极组合进行选择，对转子结构进行分析与设计，提出通过不均匀气隙和极弧系数的组合优化方法，有效削弱“一”形磁钢内置式永磁电机的齿槽转矩。根据设计参数制作了样机，设计值与实验值的误差较小，电动机用于注塑机的伺服系统改造，并取得较好的节能效果。In order to improve the energy efficiency of the hydraulic injection molding machine, a permanent magnet synchronous motor for the injection molding machine is designed to transform the servo system of the injection molding machine. Combined with the actual production conditions of the injection molding machine, the main dimension parameters of the permanent magnet synchronous motor used in the injection molding machine were determined, and the finite element model was built using Ansys Maxwell 2D software. The article focuses on the selection of the slot combination, analyzes and designs the rotor structure, and proposes that the cogging torque of the ＂1＂ magnet built-in permanent magnet motor can be effectively weakened by a combination of inhomogeneous air gap and pole arc coefficient optimization methods.. According to the design parameters of the prototype, the design value and the experimental value of the error is small, the motor used in injection molding machine servo system transformation, and achieve better energy-saving effect.
