An electric rotating machine has a rotor having N and S poles and includes a stator with an annular stator core and slots. Multiple-phase stator windings are embedded in the slots, and are formed by winding continuous wires such that straight parts of the stator windings pressed in a flat shape are wound in rings around a grooved cylindrical member. The cylindrical member is inserted into a bore defined by the annular stator core so that the grooves of the cylindrical member are arranged opposite to the slots. The sets of the windings are folded back alternately outside the slots of the stator core and are wound so the sets of the windings are embedded alternately in the direction of the depth of the slots. Leading and trailing ends of the continuous wires are superposed after being wound at least one turn around the circumferentially arranged slots of the stator.

Electric rotating machine and stator for the same

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.

Vehicle use ac generator

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.

Rotary cooling fan for an AC generator

A power source system for a vehecle is disclosed. The system has a generator driven by an internal combustion engine, a control equipment for controlling the generator, a battery, a heater which is heated by the generated output of the temperature detecting means for detecting generator, and a temperature of the heater. The system has a switch between the heater and between the generator and the generator and the battery. The heater and the battery are connected in parallel to each other.
