摘要：

Because the two mass centers of motor rotors can hardly suspend along a straight line, unbalance vibration is intensified in the high-speed magnetically levitated motor drag experiment. The model of rotor shaft unbalance vibration is proposed by regarding the disturbing force between the couplings as the same-frequency disturbances. In order to make the rotor spin around its inertial axis, a generalized notch filter is used to identify the same-frequency component as displacement compensation signal. Experiment results demonstrate that the method has good inhibitory effect on the unbalance vibration of motor rotor, oscillations of rotor's position reduce by about 80% and control current peak-to-peak reduces by about 65%, synchronous vibration is reduced to the original 28.7% at the speed of 36000 r/min. Power consumption is slightly lower and drag experiments can stable run at rated speed. © 2014 Journal of Mechanical Engineering.
