Abstract: In order to solve the problems of large volume, short service life and high cost of electrolytic capacitor controller used for washing machine motor, the scheme of using non-electrolytic capacitor controller is proposed, but the problem of electromagnetic vibration of motor caused by non-electrolytic capacitor control is very large. Through the study of the influence mechanism of non-electrolytic capacitor on electromagnetic vibration, the generation mechanism of non-electrolytic capacitor electromagnetic vibration is quantitatively analyzed by electromagnetic simulation, which provides theoretical support and improvement ideas for the subsequent optimization design of non-electrolytic capacitor vibration. Based on the results of this study, the use of the stator laminations sample mechanism optimization combining with the current control scheme for sample and test verification, the results show that electromagnetic vibration improvement effect is obvious, fell by 50%~90%, vibration amplitude of the electromagnetic vibration to electrolytic capacitor motor vibration level, the result has played a very good damping effect, this study has guiding meaning for actual engineering application.
