The cover body 461 and the connector portion 462 may be integrally formed, such that the cover 460 is a one piece construction. Alternatively, the connector portion 462 may be separately disposed from the cover body 461.

The connector portion 462 is disposed at an axial end of the drive device 40 (e.g., along the axis Ax). The connector portion 462 has an opening that faces away from the motor 80. The connector portion 462 includes a power supply terminal 463 and a ground terminal 464. The end of the power supply terminal 463 on the connector portion 462 connects to a power supply (not shown). The end of the ground terminal on the connector portion 462 connects to ground or a power return path (not shown). The other ends of the power supply terminal 463 and the ground terminal 464 are connected to the substrate 30. The power supply terminal 463 and the ground terminal 464 may also be referred to as the outermost terminals 463 and 464.

Although not shown in FIG. 2, the connector portion 462 may additionally include a control terminal including a vehicle communication terminal to connect the drive device to a vehicle communications systems and a torque terminal to connect the drive device 40 to the torque sensor 94. The control terminal and the torque terminal may be integrally formed in the connector portion 462 or may be separate parts from the connector portion 462. The number of connectors and the number of terminals may be arbitrarily changed, for example, based on the number of input/output signals to/from the drive device 40.
