To solve the problem of excessive torque pulsation in surface-inset permanent magnet synchronous motors, a non-uniform three-segment surface-inset Halbach permanent magnet synchronous motor structure based on an eccentric magnetic pole is proposed. Firstly, the electromagnetic performance of the motor structure is analysed using the finite element method to establish the motor simulation model. Secondly, Pearson correlation analysis was used to stratify the initially motor structural parameters into strong and weak layers. Optimization is carried out using an improved multi-objective particle swarm optimization algorithm, Taguchi’s method and parameter scanning method, respectively. Finally, simulation experiments were carried out using the finite element method and compared with the electromagnetic performance of the motor before optimization. The results show that the optimized proposed structure has suppressed the torque pulsations, significantly reduced the cogging torque, improved the air gap density sinusoidality and suppressed the harmonic amplitude, effectively improving the electromagnetic performance of the motor.
