摘要： Since a structure of a cooling fan of an alternative current generator for a vehicle is formed with a resin molding product having an insert metal fitting, a freedom degree on said fan design shape configuration and said installation performance of said fan to a core can be compatible. A cooling fan structure having a high shape configuration design freedom degree and having an installation strength similar to that of said fan according to said prior art can be obtained.

摘要： To reduce noise, there is provided an alternator for motor vehicles having a rotor and a stator which is mounted between a pair of brackets. In the alternator a stator core forming the stator is made up of laminations of thin sheets. And at least a part of the thin sheets making up the stator core are split into four divisions or more in the circumferential direction; the thin sheets of each layer being laid with splits thereof arranged alternately in the circumferential direction.
