Abstract
A core has a plurality of plate-shape core pieces with a magnetic pole tooth and having connecting portions formed at one end and having a first circular arc end surface and having at the other end a second end surface which can mate with the first end surface of an adjoining core piece. The core pieces are arranged in the shape of a strip through the end surfaces to form a first core member and a second core member. The core members are stacked so that the ends of adjoining core pieces in the stacking direction overlap and such that adjoining connecting portions can freely rotate through connecting means to form a ring with the magnetic pole teeth on the inside. A cutout is formed in the corner of the outer side of the core in the second end surface of each core piece.
