摘要: To provide an electric driving device and an electric power steering device that have a smaller size in the axial direction and suppress stress on a circuit board due to electrical connection between a motor and the circuit board if a terminal block is provided. An electric driving device includes a motor and an electronic control unit that controls rotation of the motor. The electronic control unit includes a first circuit board, a first heat sink, a second heat sink, and a terminal block. The second heat sink sandwiches the first circuit board between it and the first heat sink. The terminal block is fixed to the side surface of the second heat sink and electrically connects motor coil wiring to the first circuit board.

摘要: An electric driving device and an electric power steering device. An electric driving device includes a motor and an electronic control unit that controls rotation of the motor. The electronic control unit includes a first circuit board, a second circuit board, a second housing, a lid, and an inter-board connector. The second circuit board includes a control circuit that controls an electric current supplied to a transistor of the first circuit board. The second housing accommodates the second circuit board and has a first through hole passing therethrough in the axial direction. The lid covers the second housing. The inter-board connector connects the second circuit board disposed on the anti-load side of the second housing to the first circuit board disposed on the load side of the second housing. The inter-board connector is disposed in the first through hole.

摘要: To provide an electric driving device and an electric power steering device with a smaller area of power supply wiring in a circuit board and higher reliability of the circuit board. An electric driving device includes a motor and an electronic control unit that controls rotation of the motor. The electronic control unit includes a first circuit board, a second circuit board, a power supply wiring module, and a heat sink. The first circuit board is provided with a transistor that outputs an electric current to excite a motor coil. The second circuit board includes a control circuit that controls an electric current supplied to the transistor. The power supply wiring module is configured by molding, with resin, a choke coil for noise removal, a capacitor, and wiring that supplies electric power to at least one of the first circuit board and the second circuit board. The heat sink is sandwiched between the power supply wiring module and the second circuit board.
