Abstract:
1. A mounting structure of a rotation detector to a motor, the rotation detector including a detection stator and a detection rotor, wherein the motor includes a rotary shaft and a motor housing internally housing the rotary shaft, the motor housing being provided with a mounting hole in a position corresponding to an end of the rotary shaft, the detection rotor is fixed to the end of the rotary shaft, the detection stator includes: a detection part made of resin in a plate-like shape, the detection part having a surface on which a planar coil is placed; an outer peripheral wall formed along an outer circumferential edge of the detection part and extending in an axial direction; and a flange extending from the outer peripheral wall in a radial direction, the mounting structure includes a fixing member for fixing the detection stator to the motor housing, and the detection stator is placed so that the surface of the detection part faces the detection rotor and the surface of the detection part faces an inside of the motor housing through the mounting hole, and the detection stator is fixed to the outside of the motor housing by the fixing member in the flange, wherein the detection stator includes a metal collar in the flange, the collar includes a hole, and the fixing member is screw mounted in the hole of the collar.
