There are many varieties of windings. Coils adopting an edgewise winding wire in which winding wires are wound around in the radial direction of the coil have a wide flux linkage area orthogonal to the electric wire, so that stray loss within the wire is increased, winding wire loss is increased and temperature is raised thereby. The present invention provides an arrangement in which a plurality of coil units are prepared and connected via external coupling terminals. At this time, winding is performed so that the contact faces of the coil units have equal potentials, so that there is no need to ensure an insulation distance between coils, and the coils can be downsized. Therefore, the mass of the respective coils can be reduced. Taps disposed on the respective coils are arranged to have equal potentials, according to which the external coupling terminals can double as tap switch terminals, so that there is no need to provide a dedicated tap switch.
