Abstract

The rotating electric machine includes a housing, a pair of bearings that is fixed by the housing, a shaft supported at opposite ends thereof by the respective bearings, a rotor mounted on the shaft for rotation therewith, and a stator disposed in such a manner as to surround the rotor. A rotational speed detection gear is mounted on the shaft for rotation therewith at a position between the rotor and one of the bearings and in a vicinity of the bearing, and the rotational speed detection gear has a plurality of gear teeth at an outer circumference thereof. A rotational speed detector is provided at a position in the housing so as to face the gear teeth of the rotational speed detection gear. A rotating member for generating a flow of air is disposed in the housing.
