Abstract
A drive device includes a motor with two sets of motor windings and a control unit. The control unit has a board on which an electronic component related to energization control of the motor windings are mounted, a connector unit, and a cover member that covers control components including the board, and is provided on one side in a axial direction of the motor. The connector unit has two main connectors and at least one sub connector used for connection with an outside, and these openings are provided so as to face a side opposite to the motor. The main connectors are connected with a power supply and a communication network. The sub connector has an opening separate from that of the main connector and is connected to a separate member.
Claims6
A drive device, comprising:
- a motor having two sets of motor windings;
- and
- a control unit including a board on which electronic components related to energization control to the motor windings are mounted, a connector unit having two main connectors and at least one sub connector used for connection with an outside, with openings of the two main connectors and the at least one sub connector facing away from the motor, and a cover member covering control components having the board;
- wherein
- the control unit is provided on one side of the motor in an axial direction,
- each main connector is connected to a power supply and a communication network, and the two main connectors are equal in height,
- the at least one sub connector has an opening separate from an opening of each main connector and is connected to a separate member, and
- lock pins that engage with a lever of a connector to be connected are provided on side walls on both sides of each main connector, wherein
- a combination of components related to the energization control of one of the motor windings is referred to as a first system, and a combination of components related to the energization control of the other of the motor windings is referred to as a second system,
- a line separating the first system and the second system is defined as a system dividing line, and
- the lock pins of the two main connectors are formed on a same straight line orthogonal to the system dividing line.
