PURPOSE:To facilitate maintenance and to shorten the longitudinal size by flowing a current to a field winding on the basis of a pole formed by flowing a current to the exciting winding of a rotor. CONSTITUTION:An armature winding 24 is provided on one rotor 13 of two rotors 11, 12 which rotates in an opposed manner, and a field winding 25 is provided at the other rotor 11. An exciting current is supplied to the winding 24 to form a pole. This pole is allowed to cross the winding 25 of the rotor 11 to induce an exciting voltage. Currents are flowed to field windings 51, 52, 57, 45, 46, 53 by the exciting voltage to form a field pole. |
