Abstract
A vibration-cancelling module includes a first rotor having a first eccentric body, a second rotor having a second eccentric body, and a stator assembly in electromagnetic communication with the first and second rotors. A central shaft extends between the first and second rotors. The first and second rotors rotationally operate about a common rotational axis with respect to one another between a balanced position and a plurality of eccentric positions. A controller has an accelerometer assembly and a rotor-position sensor assembly. The controller delivers an electrical current to the stator assembly at least based upon the accelerometer assembly. A common housing contains the first and second rotors, the stator assembly, the central shaft and the controller.
