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.

Abstract: There is provided a method of manufacturing an electric motor. To begin with, a stator is provided by fixing a stator winding on a stator core. The stator winding has a coil end projecting from one end face of the stator core. Subsequently, a lead wire is drawn out from the coil end radially outward thereof. A connecting terminal is fixedly mounted to a distal end of the lead wire. A terminal block is provided such that the terminal block is held at a position to be finally fixed relative to the stator. The lead wire is bent toward the terminal block. The connecting terminal is electrically connected to the terminal block. An insulator is coated on the lead wire and the coil end by impregnating the lead wire and the coil end with liquid insulating material.
