Claims

[Scope of utility model registration request]

An excitation coil fixed to the rotating shaft side, a magnetic pole core of the rotor excited by the excitation coil, a stator core surrounding this pole core, a stator coil attached to the stator core, and the above-mentioned rotating shaft. comprising a front bracket and a rear bracket that are arranged opposite to each other in the axial direction of the shaft and support the stator core to which the stator coil is attached, and also pivotally support the rotating shaft;
The rear bracket has an annular surrounding groove that surrounds the rear end of the stator coil with a gap, and a three-phase lead wire drawn out from the rear end of the stator coil is arranged on the rear side of the rear bracket. In the vehicle alternator, the alternating current generator is provided with a through hole for leading to the rectifier, and the gap is filled with an insulating filler having good thermal conductivity, and the end face of the stator coil near the through hole and the three An AC for a vehicle, characterized in that an outlet cover made of an insulating material is inserted into the through-hole of the rear bracket so as to cover the phase-outline wire and fill the gap between the three-phase outlet wire and the through-hole. Generator.
