Each insulator includes projections projecting further than a tooth front end part in the circumferential direction, slits which are formed in the respective projections to a corresponding axial end surface side of the tooth front end part and into which the insulating film is inserted, and ribs formed, on an end surface side in the circumferential direction, in the respective projections. The insulating film inserted into the slits is folded back to a back yoke part side with the ribs interposed therein, and fixed by being interposed between the ribs at tip portions of projections of adjacent insulators. Accordingly, the insulating film can be assuredly fixed and prevented from escaping from a slot.

摘要： A laminated core manufacturing method is linearly arranging and punching out a plurality of separate core pieces formed of a back yoke portion and a magnetic-pole teeth portion protruding from the back yoke portion and die-cut caulking. The manufacturing method includes: a first step of punching out a first region located on an opposite side to the magnetic-pole teeth portion between adjacent ends of the back yoke portions of the core pieces; a second step of punching out a second region located on a side of the magnetic-pole teeth portion between the adjacent ends of the back yoke portions of the core pieces; a third step of punching out a region that brings the first region punched out in the first step and the second region punched out in the second step into communication; and a fourth step of forming the magnetic-pole teeth portion by punching.
