Document Type and Number:
Japanese Patent JP6770863
Kind Code:
B2
Abstract:
An electric drive device includes a motor housing including a housing end face part opposite to an output part of a rotating shaft of an electric motor. The housing end face part includes a power conversion circuit part heat dissipation section and a power supply circuit part heat dissipation section formed to allow at least generated heat of the power conversion circuit part and the power supply circuit part to be transferred to the motor housing. A sensor magnet is fixed to an end part of the rotating shaft opposite to the output part of the rotating shaft and structured to constitute a rotation-sensing target part for sensing rotation of the rotating shaft. The power conversion circuit part heat dissipation section of the housing end face part is positioned closer to the electric motor than the sensor magnet.
