Abstract
An alternator is composed of a frame, a rotor rotatably supported in the frame, a stator contained in the frame outside the rotor and other associated components. A front end of the alternator is directly mounted on a mounting surface of an engine having a fairly large size, and a front end of a rotor shaft is directly connected to an engine shaft. The frame includes inlet windows for introducing cooling air into the alternator and outlet windows for exhausting the cooling air after cooling a stator coil and other components in the alternator. The inlet and outlet windows are positioned so that cool air is always introduced into the alternator, preventing hot air once exhausted from the alternator from staying between an engine bracket and the inlet windows and being sucked again into the alternator. Further, the outlet windows are positioned at a radial outside of a front coil end of a stator winding, so that the front coil end is fully exposed to the cooling air.
