摘　　要：针对无齿轮球磨机直驱永磁电机体积过大带来的制造、运输、装配及维护困难等问题,采用去除线圈绕组实现低速大功率直驱永磁电机结构的模块化,使电机实现模块化制作、运输、安装,增强了电机的制造灵活性、运行可靠性、可维护性。阐述了模块化直驱永磁电机的结构,并对其去除线圈绕组进行了分析,总结了设计方法。在此基础上设计制造了一台样机,采用有限元方法进行了仿真分析,最后搭建实验台进行了实验。仿真结果和实验结果都验证了所提结构和设计方法的合理性。Aiming at the difficulties in manufacturing,transportation,assembly and maintenance caused by the excessive size of the direct drive permanent magnet motor of the gearless ball mill,the modularization of the structure of the low-speed and high-power direct-drive permanent magnet motor is realized by removing the coil winding,so that the motor can be manufactured,transported and installed in a modular manner,and the manufacturing flexibility,operation reliability and maintainability of the motor are enhanced.The structure of the modular direct-drive permanent magnet motor is introduced,and the removal of the coil winding is analyzed,and the design method is summarized.On this basis,a prototype machine is designed,and the simulation analysis was carried on by using the finite element method.Finally,a test-bed of model machine is built to carry out the experiment.The simulation and experimental results are presented to verify the rationality of proposed structure and design method.
