【Abstract】 To efficiently improve the performance of double stator vernier permanent magnet(DS-VPM) motors with considering parameter fluctuation, the multi-level robust optimization design approach was proposed. By the proposed multi-level robust optimization approach, the relevance between motor design parameters and motor performance was investigated based on flux modulation theory, and the key harmonics affecting the electromagnetic performance of motor were identified. The sensitivity analysis method was used to reduce the dimension of motor design parameters. To comprehensively consider the influence of motor design parameter fluctuations on motor performance, the multi-level robust optimization design approach was adopted to realize the optimal robust motor design with high output torque, low torque ripple and low iron loss under different operation modes. The results show that the proposed multi-level robust optimization approach is verified by the performance comparison and experiments.更多还原
