る回転電機。A cooling fan is fixed to the rotor shaft and provided in the stator housing, and a slit ring is provided on the outer surface of the fan extending in the circumferential direction, and a slit ring is provided on the stator housing mirror cover facing the slit ring. Install a speed sensor,
Further, in the rotating electric machine, an air hole is provided in a portion near the outer periphery of the mirror lid for preventing negative pressure generated in the space between the inner surface of the mirror lid and the outer surface of the fan due to the air blowing action accompanying the rotation of the fan by introducing outside air, A partition wall is provided on the outer periphery of the slit ring and the speed sensor and on the inner periphery of the air hole, protruding from either or both of the outer surface of the fan and the inner surface of the mirror cover to prevent air flow. A rotating electric machine.
