Abstract

PURPOSE: To prevent an effect from affecting the power source system and a shaft of the machine side from being broken, without using a starter like reactors, by such means that, with the same phase stator windings of a plurality of AC motors connected in series to each other, a voltage-reducing start be simultaneously operated.
CONSTITUTION: Each phase stator winding of an induction motor 14 is connected to a magneblast breaker 32, and each phase winding of an induction motor 24 is arranged, with its one end in stat-connection and another end connected to a connection point, between the breaker 32 and the motor 14, through a magneblast breaker 31. Accordingly, with a breaker 11 and the breaker 31 made closing and the motors 14, 24 simultaneously operated a voltage-reducing start, after the completion of starting operation, the steady operational condition is reached both for the motor 14, with the breaker 32 made closing, and the motor 24, further with the breaker 31 made opening and the breaker 21 closing, thus capable of simoltaneously starting a plurality of sets of motors with the starting current and torque suppressed to eliminate an effect affected to the power source.
