摘要： 针对大功率电机运行过程中出现的可靠性和运行维护问题，提出了一种新型独立模块式永磁同步电机结构，建立了独立模块式永磁电机的数学模型，分析了相邻模块间绕组电感耦合.该电机可实现定子自由拆分，且各模块电机能够独立运行.通过提出的父子模块概念，将一些子模块重组为父模块，实现模块间绕组电感的解耦.同时，通过将父模块中的子模块定子绕组进行换相，解决了由于模块不连续引起的三相绕组参数不对称问题.有限元分析结果验证了所提独立模块式永磁电机结构的可行性.

Abstract: Aiming at the problems of reliability and maintainability during the operation of high power machine， the structure for a novel independent modular Permanent Magnet Synchronous Machine (PMSM) was designed. The mathematical model of modular PMSM was established and the inductance coupling of three-phase winding between the neighboring modules was analyzed. This machine was composed of detachable stators， whose modular machines could operate separately. Through the proposed concept of parent modules and sub-modules， parent modules were recombined with sub-modules to achieve the inductance decoupling between modules. Meanwhile， by exchanging the winding phase of sub-modules in parent module， the problem of asymmetric three-phase winding parameters caused by the discrete modules was also solved. The feasibility of structure for this machine was proved by the results of finite element analysis.

Key words: isolated module, PMSM, inductive coupling, parent modules, sub-modules
