ABSTRACT:
A starter-alternator of a vehicle of the type being disposed between a vehicle engine and a transmission case having a field pole member coupled to an engine crankshaft of the vehicle engine. Crow-poles are interspaced to form alternating N and S poles. A field winding is stationarily placed radially inside the crow-poles. A three phase stator winding is stationarily placed to surround the crow-poles, and a housing accommodates the stator-alternator elements therein and connects the vehicle engine and the transmission case. The housing is provided with an air passage for introducing fresh air into the housing so as to blow it toward the three phase stator winding in order to cool it, and an air outlet pipe discharges air inside the housing. In association with either one or both of the windings, a water pipe in communication with a water jacket of the vehicle engine is provided to circulate cold water therethrough.
