Abstract
PURPOSE: To prevent unnecessary thermogenesis in magnetic field coil by making easier the establishment of voltage by strengthening the excitation force of magnetic field coil only at the time of voltage establishment.
CONSTITUTION: At the time of voltage establishment, the closed contact 10 and the movable contact 9 of the relay 7 are in contact with each other, so that voltage whose full-wave is rectified by the full-wave rectifying bridge 5 is supplied to the magnetic field coil 4. When the terminal voltge of the armature 1 reaches a predetermined value by establishment, the closed contact 10 of the relay 7 is separated from the movable contact 9, and thus full-wave rectified voltage through the rectifier 3a and the full-wave rectifying bridge 5 is supplied to the magnetic field coil 4.
