Document Type and Number:
WIPO Patent Application WO/2016/166796
Kind Code:
A1
Abstract:
An electric driving device, in which a sensor magnet is fixed to a first end section of the rotation shaft of a motor. A sensor device has a rotation sensor for detecting the magnetic field of the sensor magnet. The rotation sensor faces the sensor magnet along the axial direction of the rotation shaft. A control unit mounted on the motor has an inverter circuit connected to the armature coil of the motor via a plurality of power supply wires. The inverter circuit is disposed, with respect to the axial direction of the rotation shaft, at a position further from the sensor magnet than the rotation sensor. A shield plate comprising a magnetic material is disposed between the rotation sensor and the inverter circuit.
