【摘要】 为了准确识别分析三相异步电动机振动的主要影响因素,采用降电压法测量并识别了电磁振动、轴承振动以及转子动不平衡引起的振动等主要成分。结合理论分析方法,对电磁力波引起的振动进行详细的分析,较好的识别了齿谐波电磁力、偏心以及饱和等多种因素引起的振动,为电动机振动噪声的针对性改进优化提供了具有参考意义的结论。更多还原

【Abstract】 In order to accurately identify the main influence factors of three-phase induction motor vibration,the electromagnetic vibration,bearing vibration and the vibration caused by rotor dynamic unbalance and other major components were analyzed by using the method of reducing the voltage. Based on the theoretical analysis method,the vibration caused by of electromagnetic force was identified and analyzed in detail,and the vibration caused by many factors,such as the electric magnetic force,the eccentricity and the saturation factor,was well recognized. It provided a reference for the further improvement and optimization of the vibration of the motor.更多还原
