Abstract
PURPOSE: To reduce vibration, noise, and mechanical loss by correcting for dispersion by the procedure in which the other opening of the coil cylinder provided with commutator holder plate is partially removed and then provided with a balance ring to balance weight with respect to the rotation center.
CONSTITUTION: One opening of the coil cylinder 1 is provided with the commutator holder 2 and also the circumference of the other opening is provided with the balance ring 4. And, a part of the balance ring is cut off by laser coming from a laser irradiation hole provided to the yoke 5 through the nozzle 12 of the laser device 11, for example. The portion to be cut off is the largest portion confirmed by the balance measuring device 13. Thus, even after the rotor is completed, the weight with respect to its rotation center can be balanced.
