Abstract
A drive device includes a motor and a controller coaxially disposed with the motor for controlling the motor. The drive device further includes a cover for covering the controller with an opening, and a connector part separate from the cover for connecting to an external connector. The connector part includes connectors that extend and protrude longitudinally through the opening of the cover. The longitudinal axis of the mouth of each connector in the connector part is arranged and angled differently relative to the mouths of adjacent connectors so that the connectors are positioned within an axial silhouette of the motor.
Claims16
A drive device comprising:
- a motor;
- a controller coaxially disposed with the motor and configured to control the motor;
- a connector part configured to connect to an external connector on an external cable;
- and
- a cover configured to cover the controller, the cover having an opening and the cover is separate from the connector part, wherein
- the connector part includes at least three connectors that extend and protrude axially through the opening of the cover in a direction of an axis of the motor, and wherein
- a longitudinal axis of a mouth of each of the at least three connectors is angled and oriented differently than a longitudinal axis of a mouth of an adjacent connector, wherein the at least three connectors are positioned within an axial silhouette of the motor,
- the connector part includes:
- a power connector configured to hold a power terminal;
- a vehicle communication connector configured to hold a vehicle communication terminal;
- and
- a torque signal connector configured to hold a torque signal terminal,
- the power terminal has an external connection end within the power connector and a substrate connection end configured to connect to a substrate of the controller, the power terminal having at least one bend between the external connection end and the substrate connection end, and wherein the substrate connection end of the power terminal is positioned at a greater radial distance from the axis of the motor than the external connection end of the power terminal,
- the vehicle communication terminal has an external connection end within the vehicle communication connector and a substrate connection end configured to connect to the substrate of the controller, the vehicle communication terminal having at least one bend between the external connection end and the substrate connection end, and wherein the substrate connection end of the vehicle communication terminal is positioned at a greater radial distance from the axis of the motor than the external connection end of the vehicle communication terminal, and
- the torque signal terminal has an external connection end within the torque signal connector and a substrate connection end configured to connect to the substrate of the controller, the torque signal terminal having at least one bend between the external connection end and the substrate connection end, and wherein the substrate connection end of the torque signal terminal is positioned at a greater radial distance from the axis of the motor than the external connection end of the torque signal terminal.
A drive device comprising:
- a motor having a first set of winding wires and a second set of winding wires;
- a controller coaxially disposed with the motor and configured to control the motor, the controller having a first system control unit configured to control power supplied to the first set of winding wires and a second system control unit configured to control power supplied to the second set of winding wires;
- a connector part configured to connect to an external connector on an external cable;
- and
- a cover configured to cover the controller, the cover having an opening and separate from the connector part, wherein
- the connector part includes at least four connectors that extend and protrude axially through the opening of the cover in a direction of an axis of the motor, and wherein
- a longitudinal axis of a mouth of each of the at least four connectors is angled and oriented differently than a longitudinal axis of a mouth of an adjacent connector, wherein the at least four connectors are positioned within an axial silhouette of the motor.
