Abstract Aiming at the large volume of low-speed and high-power machines bringing the problems of manufacturing, transportation, installation and maintenance difficulties, a permanent magnet synchronous machine with modules combination stator based on unequal span winding was proposed. This structure achieves modular manufacturing of low-speed and high-power machines, and enhances the manufacturing flexibility, operation reliability, maintenance and fault tolerance. This paper describes the structure of the permanent magnet synchronous machines with modules combination stator, and its design method was summarized. Meanwhile, the partitioning principle and q selection method was studied. On this basis, a prototype machine was designed, and the simulation analysis was carried on by using the finite element method. At the same time, the self-inductance and mutual-inductance parameters of prototype were calculated by analytical method and incremental inductance method respectively. Finally, a test-bed of model machine was built to carry out the experiment. The simulation and experimental results were presented to verify the rationality of proposed structure and design method.
