Influence of modular combined stator structure with centralized winding on the performance of low speed high power permanent magnet motor
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.
