Two schemes have been developed to reduce the cogging torque generated by the gap between the stator modules of the modular permanent magnet synchronous motor. These schemes involve shifting the gap position to change the phase of the cogging torque, thereby eliminating some of its components and reducing its magnitude. Finite element simulation was used to verify the cogging torque of E and C type modular motors using two different schemes. The effect of the offset gap on electromagnetic performance and motor vibration noise was also analysed. The results indicate that both schemes weaken the cogging torque without significantly affecting the electromagnetic performance of the motor or increasing vibration noise.
