ABSTRACT:
In a method of adjusting the balance of the rotor of an AC generator which comprises a pair of magnetic pole cores with magnetic pole claws which are intertwined with each other, the amount and direction of unbalance of the rotor are detected, the amount of unbalance thus detected is divided into two components along the center lines of adjacent magnetic pole claws, a hole is drilled in the outer peripheral surface of the magnetic pole claw on which the larger of the components lies in such a manner that the hole is in alignment with the center line of the magnetic pole claw; and those operations are carried out repeatedly until the balance thus adjusted falls in a predetermined range of allowance, whereby the balance of the rotor is readily adjusted with high accuracy.
