  • Patent number: 11413972
    Abstract: A powertrain backlash control system is provided for use with an electric vehicle (EV), where the EV uses at least one powertrain to provide forward vehicle motion and at least one additional powertrain to provide rearward vehicle motion. The control system eliminates backlash by maintaining a positive motor torque within each powertrain when the vehicle is in-gear, thus applying a minimum forward torque demand to the powertrain dedicated to forward motion and applying a minimum reverse torque demand to the powertrain dedicated to rearward motion.

  • Patent number: 11418140
    Abstract: An induction motor controller is provided. The induction motor controller includes a first module that derives a commanded stator voltage vector, in a rotor flux reference frame, via a rotor flux regulator loop and a torque regulator loop, which process at least partially in the rotor flux reference frame. The induction motor controller includes a second module that processes the commanded stator voltage vector to produce AC (alternating current) power for an induction motor.

  • Patent number: 11394270
    Abstract: A gear assembly is provided that simplifies the integration of a differential assembly into the hollow rotor of an electric motor. The gear assembly utilizes a hollow cross member that includes a central portion and a plurality of hollow extension members onto which the gears are mounted. Within each of the hollow extension members is a pin. When the pins are withdrawn, the assembly fits unimpeded within the hollow rotor. When the pins are partially extended out of the corresponding extension members, the ends of the pins fit within apertures in the rotor. A plug fits within a centrally located thru-hole in the central portion of the hollow cross member, thereby locking the pins in the extended position and locking the gear assembly in place.

  • Publication number: 20210351642
    Abstract: An electric motor cooling system is provided that utilizes stator-integrated axial coolant channels and a coolant manifold centrally located within the stator to efficiently remove motor assembly heat. The coolant manifold includes a middle member that allows coolant to enter the axial coolant channels via transition laminations, where the transition laminations include coolant distribution channels that direct the flow of coolant entering into the manifold into the stator-integrated axial coolant channels.

  • Publication number: 20210347245
    Abstract: An electric motor cooling system is provided that utilizes stator-integrated axial coolant channels and a coolant manifold centrally located within the stator to efficiently remove motor assembly heat. In order to increase the velocity of the coolant exiting the axial coolant channels, thereby improving end winding cooling uniformity, end laminations are integrated into the stator which restrict the flow of coolant from the axial coolant channels.

    Abstract: An electric motor cooling system is provided that utilizes stator-integrated axial coolant channels and a coolant manifold centrally located within the stator to efficiently remove motor assembly heat. In order to improve end winding cooling uniformity, two or more end laminations are included on either end of the stator assembly which restrict and direct the flow of coolant exiting the axial coolant channels.

  • Patent number: 11133719
    Abstract: A stator assembly is provided that simplifies the process of coupling the stator windings to the winding lugs. The stator assembly includes a pre-fabricated connector that is attached to the stator via a plurality of stator winding terminations. The pre-fabricated connector includes a plurality of electrically conductive termination coupling members that form conductive pathways between at least a portion of the stator winding terminations and a plurality of bus bars, where each of the bus bars includes a lug. The pre-fabricated connector may also include a second plurality of electrically conductive termination coupling members that form conductive pathways between at least a second portion of the stator winding terminations and a plurality of lugless bus bars. An electrically insulating material is overlaid over portions of the connector ring, thereby preventing contact or partial discharge between the various bus bars.

  • Publication number: 20210276425
    Abstract: A power distribution system is provided that ensures that a car is able to operate safely in an autonomous mode. The system includes multiple power rails, including a pair of safety critical power rails. Associated with each safety critical power rail is a safety switch, vehicle sensors (e.g., vehicle location and obstacle sensors), vehicle actuators (e.g., braking and steering actuators) and an autonomous control unit. If a fault is detected during vehicle initialization or general operation, the safety switch which detected the fault opens and that particular power rail is decoupled from the general purpose power rail as well as the remaining safety critical power rail. The remaining safety critical power rail is then able to provide power to a sufficient number of sensors, actuators and controllers to allow the car to safely and autonomously complete an emergency stop on the side of the road.
