PURPOSE:To permit the increase of the number of windings of a driving coil in a narrow space, by a method wherein printed coils and flat coils formed by winding lead wires, are combined to make the driving coil. CONSTITUTION:A flat coil 24b, a printed coil 5b, the printed coil 5a and the flat coil 24a are connected in series so as to together constitute a driving coil for phase U. The printed coils 6a, 7a,... are connected to the flat coils 25a, 26a,... whereby a driving coil far phase V is constituted while the driving coil for phase W is constituted by connected the flat coils 25a, 26a to the printed coils 6a, 7a. The flat coils 24a, 25a, 26a are soldered to the printed coils 5a, 6a, 7a,... or printed lead wires 12, 13, 14,... and are attached to the adaptor frame for the coils.
