    摘要: Heat radiation base body 23 that is adjacent to electric motor unit EM and extends in direction of rotation shaft 50 of electric motor is provided close to rotation shaft 50 of electric motor. Board 24 of one electronic control unit of redundant system is fixed to heat radiation base body along direction in which heat radiation base body 23 extends with thermal conduction to heat radiation base body 23 allowed. Board 26 of the other electronic control unit of redundant system is fixed to heat radiation base body so as to face to board 24 of one electronic control unit of redundant system, with thermal conduction to heat radiation base body 23 allowed. Size reduction of electric drive device in radial direction can be achieved. Since heat radiates to housing of electric motor unit through heat radiation base body, heat from board can radiate efficiently to the outside.

    摘要: In an electric power steering apparatus, a motor housing includes an axial end part opposite to an output part of an electric motor. An electronic control section is arranged at the axial end part of the motor housing. The electronic control section includes a control circuit part, a power supply circuit part, and a power conversion circuit part. The axial end part of the motor housing includes a power conversion part thermal radiation region and a power supply part thermal radiation region. The power conversion circuit part is mounted to the power conversion part thermal radiation region to allow heat to be transferred from the power conversion circuit part to the motor housing. The power supply circuit part is mounted to the power supply part thermal radiation region to allow heat to be transferred from the power supply circuit part to the motor housing.

    摘要: An actuator module is provided. The actuator module includes a motor part including a drive shaft and a drive part configured to rotate the drive shaft, a reducer installed on one side of the drive part and configured to increase an output torque according to driving of the motor part, a brake installed on an opposite side of the drive part and configured to suppress rotation of the motor part, an encoder installed on one side of the brake and configured to sense an operation of the drive shaft, a controller installed on one side of the encoder and electrically connected to the motor part to control the motor part, and a first housing configured to surround the motor part, the reducer, the brake, the encoder and the controller. An airflow path through which an airflow can flow is formed to extend from the motor part.
