Abstract: In order to improve the output performance of the offshore generator, the rotating motor of the two-degree-offreedom motor was taken as the research object. the parameters of permanent magnet size and stator core size are set as the optimization factors. The optimal parameter combinations are determined for the three optimization objectives of no-load electromotive force, harmonic distortion rate and rack and pinion torque by combining Taguchi's method and multi-attribute decision-making analysis, the experimental results are verified through simulation with the finite-element method. The results show that the optimized design of the two-degree-of-freedom rotary generator based on Taguchi 's method and multiattribute decision-making can significantly improve the output harmonic distortion rate and cogging torque of the motor, and
enhance the output performance of the motor.
