Abstract: A fluid pump includes a motor disposed within an outer housing. The motor includes a stator and a rotor in electromagnetic communication with the stator. Windings are disposed on the stator that receive an electric current for defining the electromagnetic communication. A pump element is attached to the rotor via a drive shaft. The pump element operates with the rotor to deliver a fluid through a hydraulic fluid path. A plurality of sensors measure information related to at least one of the stator, the windings, the rotor, the pump element, the fluid and the hydraulic fluid path. A controller is in communication with the windings for delivering the electric current to the windings. The controller is also in communication with the plurality of sensors for measuring and recording the information and communicating this information to one of an external memory and an external controller.

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 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.

Abstract: A rotor assembly for use with a stator is disclosed. The rotor assembly includes a shaft that defines at least one outer diameter. The rotor assembly also includes a body that defines at least one interior diameter. The shaft is received within the at least one interior diameter of the body. The body is provided with a magnetic field with alternating polar arrangements as a function of a circumferential position about a circumference of the body.
