1. A vibration-cancelling module comprising:
a first rotor having a first eccentric body;
a second rotor having a second eccentric body;
a stator assembly in electromagnetic communication with the first and second rotors;
a central shaft that extends between the first and second rotors, wherein 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 having an accelerometer assembly and a rotor position sensor assembly, wherein the controller delivers an electrical current to the stator assembly at least based upon the accelerometer assembly; and
a common housing that contains the first and second rotors, the stator assembly, the central shaft and the controller, wherein each of the first and second rotors includes a dedicated magnetic assembly, wherein each dedicated magnetic assembly includes motor communication poles that are in electromagnetic communication with the stator assembly and rotor position sensor poles that are in electromagnetic communication with the rotor position sensor assembly.
