Electric drive apparatus

摘要

Provided is an electric drive apparatus in which a detected portion (10) of a rotation angle sensor is disposed at an end of a shaft (7) of a motor, and a sensor portion (300) as a detection portion of the rotation angle sensor is disposed coaxially with the rotating axis of the shaft. In a control unit (200), an inverter circuit portion with a drive element (SW) for driving the motor, and a control substrate (17) which is separate from the sensor portion and controls the output of the inverter circuit portion are disposed. The sensor portion and the control substrate are electrically connected, with the control substrate disposed along a plane perpendicular to the rotating axis of the shaft.
