Abstract

PURPOSE: To fix an exciting coil and at the same time a centrifugal fan and a buffle plate and to lower magnetic noise level, by forming a leakage hole to a buffle plate from which impregnated sticking agent leaks to the centrifugal fan.
CONSTITUTION: Six circular leakage holes 73 are formed in the position corresponding to that of a V-shaped groove 52b between each click section 52a of a core 52 at the rear of a rotor core 5 so that the impregnated liquid may leak out to a centrifugal fan 6 side and corresponding to that of the recessed part on the more internal circumferential side than the position where a cooling fan wing 61 of the centrifugal fan 6 is provided. Consequently, when the exciting coil is fixed to the rotor core 5 with impregnated sticking agent, a base 62 of the centrifugal fan 6 and a buffle plate 7 are fixed with the impregnated liquid, so that the vibration of the rotor core 5 by the magnetic force generated by an AC generator can be prevented.
