摘要： An annular core used in a so-called air axial gap motor includes a magnetic and structural gap along the axial direction. By using a compressed molded body of a mixture of a magnetic metal powder and an electrically insulating resin as major constituents, an annular molded body and a molded plate are prepared. The annular molded body has slots and teeth alternately formed along the circumferential direction. The molded plate closes the upper portions of the slots to constitute a fully closed slot structure.
