PURPOSE:To contrive to increase the operational efficiency, to reduce the axial measurements and to lower the cost for subject induction machine by a method wherein an interrupter, to be used to control the secondary side output circuit of a rotor, is equipped with a rotor in such manner that they are formed in one body and the interrupter is controlled from outside. CONSTITUTION:When the secondary side output circuit on the rotor 2 is connected to the interrupter and the interrupter is controlled at its impulse ratio, the interrupter 4 is equipped with the rotor 2 in such manner that they are formed in one body and the interrupter is controlled from outside using a sliding ring 5 and a noncontacting type rotating transformer. Through these procedures, the operational efficiency is increased as compared with the case where the secondary side output circuit is controlled by a variable transformer and the axial dimensions can be reduced. |
