Abstract
A thin metal sheet is laminated to form in advance a plurality of core units (of a circular cylinder shape) having the thickness of 1/N (N is a natural number of more than 2) of a predetermined thickness in the laminating direction and this plurality of core units is laminated again for securing so that the whole stator does not cause any mode of oscillation in the diametric direction.
