要約(英語): The dynamic eccentricity of rotors is a significant obstacle in their manufacturing process. This obstacle causes an imbalanced electromagnetic force and generates unexpected vibrations and acoustic noise. In this study, the effects of dynamic eccentricity on the temporal and spatial harmonic distributions of gap magnetic flux density and electromagnetic force are investigated, and the cause of the vibration is identified. Moreover, a compensation method is proposed to suppress the vibrations due to dynamic eccentricity by using a multi-sector and multi-phase motor. The compensation current is obtained by optimization. The effectiveness of the proposed method is verified by finite element analysis and experiments.
