Abstract
Depressed portions for being fitted with two rotor collarsare formed in two rotor stacksopposed to each other in an axial direction of the rotating shaftwith the rotor collarstherebetween. Each of the rotor collarsincludes a central portionand a pair of fitting portions. Shapes of the depressed portionsA and fitting portionsare both defined so that there occurs no relative displacement in the radial direction of the rotating shaftbetween the rotor stacksand the rotor collarswith the fitting portionsfitted into the depressed portionsA. With this arrangement, position alignment of rotor collar and rotating shaft can easily be performed.
