Title: ROTARY ELECTRIC MACHINE AND METHOD FOR MANUFACTURING ROTARY ELECTRIC MACHINE
Abstract:
According to the present invention, a sensor unit (41) accommodates a sensor (43) which detects a rotation position by detecting the magnetic flux of a rotor. The sensor is disposed in a sensor gap between two neighboring magnetic poles (32a). The sensor unit, by means of a cover (53), extends in the axial direction from an end surface (SD1) side on one side of a stator into the sensor gap. A coil wire (33d) facing the sensor unit is disposed on the end surface side while being spaced apart from the magnetic poles in the radial direction. Accordingly, interference between the sensor unit and the coil wire is suppressed. Consequently, a reduction in the accuracy of detecting the rotation position caused by interference between the sensor unit and the coil wire is suppressed.
