Document Type and Number:
WIPO Patent Application WO/2024/057683
Kind Code:
A1
Abstract:
Provided is an electric drive device of which the outer diameter size can be reduced, and the layout of a power harness and a signal harness can be changed. The electric drive device is one in which a motor and a control unit are integrated coaxially with a motor output shaft. The control unit is arranged on the side of motor that is opposite from the output side, and is electrically connected to the outside via a wire harness. The electric drive device has a connector block having first and second connector parts each having a connector connection opening to be connected to a mating connector, and a circuit board to which connection terminals of the first and second connector parts are electrically connected. The second connector part is arranged on an exterior surface different from a connector formation surface where the first connector part is located, or on an exterior surface different from the exterior surface that covers the circuit board.
