PURPOSE:To enable to reduce the thickness of a motor by integrally coupling a coil bobbin formed by mounting the bobbin of a one side flange on a core through a thin insulating means back-to-back between the outsides of the cores. CONSTITUTION:Pole teeth 4a, 5a are respectively formed on cores 4, 5, a thin annular flange 6a and a winding body 6b are formed on the bobbin 6 of one side flange, and an insulating plate 7 which is thinner than the flange 6a is annularly formed. The annular inner edge 7a of the plate 7 is engaged with the outer periphery of the pole teeth 4a, 5a of the cores 4, 5, respectively, and the winding body 6b of the bobbin 6 is engaged with the outer periphery of the pole teeth 4a, 5a to form a coil bobbin. The coil bobbin formed in this manner is associated back-to-back between the outsides of the cores 4 and 5, an exciting coil 8 is wound, and associated in cases 2 and 3, respectively.
