摘　　要：针对集中绕组模块组合式定子结构对低速大功率直驱永磁同步电机性能的影响进行研究。首先介绍了模块化定子的分块规则和分块数。基于绕组函数法推导了单个定子单元模块在不同拆分方式下的绕组函数和电感表达式。基于有限元仿真先分析了仅绕组分块对电机性能影响;然后分析了冲片和绕组都分块对电机性能影响。通过对比空载和负载性能,总结出各种定子模块化拆分方案的优缺点,为大功率低速直驱永磁同步电机的模块化设计与制造建立了基础。The influence of modular combined stator structure with centralized winding on the performance of low speed and high power direct drive permanent magnet motor is studied.At first,the modular rule and modular num⁃ber of the modular stator are analysed.The winding function and inductance expressions of a single stator unit mod⁃ule with different modular modes are derived based on the winding function method.Based on the finite element simulation,the influence of modular winding on motor performance is analyzed firstly,and then the influece of modular winding and modular stator core on motor performance is analyzed.By comparing the no⁃load and on⁃load performance,the advantages and disadvantages of different modular modes are summarized,which establishes a foundation for the modular design and manufacturing of high⁃power and low⁃speed direct⁃drive permant magnet syn⁃chronous motor.
