To control effectively unbalanced vibration caused by mass unbalance of electric spindle-tools system, the paper proposes a new active control strategy for suppressing grinding electric spindle-tools system unbalance vibration,which bases on the LMS algorithm adaptive filter. Suppressing vibration force in control scheme originates from the principle of a bearingless motor having a radial magnetic force generation. First, the winding arrangement and principle of the induction-type two windings electric spindle and radial control force model are investigated. The dual windings induction-type flexural electric spindle-tools dynamic model is established by finite element and the FBLMS adaptive filter control algorithm is investigated, the coefficients of the control force and unilateral magnetic pull are determined. The tools vibration control effect is investigated by comparing the classic PID controller and FBLMS adaptive filter controller. The results show that the FBLMS adaptive filter controller have a better control effect on suppressing the unbalanced vibration of electric spindle-tools system.
