Kind Code:
A1
Abstract:
One aspect of this drive device comprises a motor, an inverter, and a housing. The motor has a rotor, a stator, and a bearing holder that holds a bearing. The housing includes: a cylindrical first housing member that surrounds the motor from the outside in the radial direction and houses the motor; and a second housing member that covers an opening on one axial-direction side of the first housing member, from the one axial-direction side of the first housing member. The inverter has a first substrate, a second substrate, and a sensor substrate that are positioned on one axial-direction side of the motor and that are connected to each other. The first substrate, the second substrate, and the sensor substrate are disposed in the stated order from the one axial-direction side to another axial-direction side. The first substrate and the second substrate are supported by the second housing member. The sensor substrate is supported by the bearing holder and has a rotation detection unit that detects rotation of the rotor.
