Abstract
A connector portion includes a first system connector that holds a first system terminal and a second system connector that holds a second system terminal. An insertion/removal direction of the first system connector and the second system connector are the same as an axial direction of a motor. The first system connector and the second system connector are arranged close to each other such that the long length directions of the frontages of the connectors are aligned, and that the interval between the connectors is smaller than the width in the short length direction of both connectors. The connectors have protrusions that project in a direction orthogonal to the direction in which the connectors are arranged.
Claims9
A drive device comprising:
- a motor having winding sets in two systems;
- a control portion arranged coaxially with the motor and being configured to control a drive of the motor;
- and
- a connector portion configured to connect an external connector which is a connector of an external cable and the motor, wherein
- the control portion includes a first system control portion configured to control energization of one of the winding sets, and a second system control portion configured to control energization of the other winding set,
- the first system control portion and the second system control portion are mounted on one circuit board,
- the connector portion includes a first system terminal connected to the first system control portion, a first system connector holding the first system terminal, a second system terminal connected to the second system control portion, and a second system connector holding the second system terminal,
- an insertion/removal direction of the first system connector and an insertion/removal direction of the second system connector are the same as an axial direction of the motor,
- the first system connector and the second system connector are arranged close to each other such that a long length direction or a short length direction of the frontages of the connectors are aligned on a straight line, and an interval between the connectors is smaller than a width in the short length direction of both connectors, and
- the first system connector and the second system connector protrude in a direction orthogonal to the direction in which the connectors are arranged, and include protrusions for locking levers provided on the external connector.
