Abstract
In manufacturing the iron core of a divided stator, a plurality of pole pieces with fitting portions formed on both sides of pole portions are laminated and fixed to one another. A plurality of the pole piece laminates are arranged in the form of a ring and the outer or inner circumference is held with a jig. A non-magnetic and high-rigidity connecting member is press-fit in the laminating direction into fitting portions of a plurality of adjacent pole piece laminates, thereby a plurality of adjacent pole piece laminates are positioned with high accuracy and rigidly connected to one another.
