Abstract
A stator is formed with two opposed magnetic poles, and first and second magnetic paths juxtaposed to each other. An output coil and a first exciting coil are wound on the first magnetic path in such a manner as to produce respective electromagnetic forces in the same phase. A second exciting coil is wound on the second magnetic path in such a manner as to produce an electromotive force in the same phase with the electromotive force produced by the first exciting coil. The first and second exciting coils supply exciting current to a field coil wound on a rotor arranged between the opposed magnetic poles during rotation of the rotor.
