ABSTRACT:
Two or more imbalance correcting openings with the same cross-sectional configuration are provided in an armature core in parallel to a shaft in such a manner as to be equally spaced on a circumference which is concentric with the shaft, and weights are inserted in the adjacent openings to thereby correct any imbalance, the number of adjacent openings being selected to be (N-1)/2+1 or less when the number n of openings is odd and to be n/2 or less when the number n is even.
