PURPOSE:To prevent the positional shift, magnetic shortcircuit or flux leakage by arranging four outside bridge sections for coupling the outside sections of adjoining pole tooth groups and one cross bridge section for coupling pole tooth groups on a diagonal in the central section thereafter integrating them and cutting. CONSTITUTION:Each pole tooth group has a plurality of pole teeth 4a, 4b, 4c, 4d and the outside of adjoining pole tooth groups are coupled through outside bridge sections 4e, 4f, 4g, 4h. Center sides are coupled through a cross bridge 4m for coupling two pole tooth groups arranged on a diagonal then the pole tooth groups 4 are overlapped so that the pole tooth groups 4a-4d are positioned on the upper face of a salient pole 2a and bonded with resin, thereafter the cross bridge section 4m is cut off and removed.
