Abstract: An electric motor includes a plurality of structural rings that define a plurality of stator teeth. Tooth sections are formed from stacks of laminations that are positioned within each stator tooth of the plurality of stator teeth. The stacks of laminations are positioned between adjacent rings of the plurality of structural rings. Bobbins are positioned over each stator tooth. Winding sections are positioned over each stator tooth and around the bobbins, respectively. The winding sections are coupled together to define a plurality of stator poles that are configured to be selectively energized. An outer ring is positioned around an outer circumference of the plurality of stator teeth. The outer ring defines a stator core and contains the winding sections within a stator cavity defined between the outer ring and an inner circumference of the plurality of structural rings.

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.

Abstract: A motor assembly includes a housing having a motor cavity. A stator is disposed within the housing. A rotor rotates within the stator and within the motor cavity about a rotational axis. A controller is coupled with the stator having a filter circuit board and a main circuit board that are interconnected at a terminal header to define a multilayer circuit board assembly. The circuit board assembly has an electrical interface and a data interface attached to at least one of the filter circuit board and the main circuit board.
