摘要

本文对软装两极感应电动机轴承座因转子静偏心引起的振动进行了理论分析。忽略磁场阻尼效应，考虑最大同极磁通，计算出最坏情况下转子和定子在最小气隙下以双电源频率振荡时的最大径向磁力。该电磁力在分析机动力学模型中实现，并计算了套筒轴承壳体的振动。

Bearing housing vibrations in soft mounted two-pole induction motors caused by static rotor eccentricity

The paper shows a theoretical analysis of the sleeve bearing housing vibrations of soft mounted two-pole induction motors, caused by static rotor eccentricity. By neglecting field damping effects and considering maximum homopolar flux, a maximum radial magnetic force is calculated — as a worst case — acting on the rotor and on the stator in the smallest air gap of the motor and oscillating with double supply frequency. This electromagnetic force is implemented in an analytical machine dynamic model and the sleeve bearings housing vibrations are calculated.
