PURPOSE:To delete the number of assembling steps and to ensure the efficiency of a motor by laminating iron plates having a bridge and iron plates having no bridge to construct a toothed core, and integrally molding fixedly the core with an insulating material. CONSTITUTION:A toothed core 4 in which small number of core plates 2 having a bridge 1 and many core plates 3 having no bridge 1 are laminated fixedly is integrally molded fixedly at the inner peripheral edge, front and rear faces, and slot interiors with an insulating material 5. Then, winding conductors 6 responsive to the number of poles are wound in series from the outer periphery of the core 4, and engaged fixedly with the inner periphery of the core 7. Thus, the molding step of the material 5 is simplified, and it is not necessary to separately provide a slot insulating step.
