ABSTRACT:
Depressed portions for being fitted with two rotor collars51, 52are formed in two rotor stacks72, 71opposed to each other in an axial direction of the rotating shaft1with the rotor collars51, 52therebetween. Each of the rotor collars51, 52includes a central portion5aand a pair of fitting portions5b. Shapes of the depressed portions8A and fitting portions5bare both defined so that there occurs no relative displacement in the radial direction of the rotating shaft1between the rotor stacks72, 71and the rotor collars51, 52with the fitting portions5bfitted into the depressed portions8A. With this arrangement, position alignment of rotor collar and rotating shaft can easily be performed.
