Abstract

PURPOSE:To disconnect the current to be supplied for a motor in case of the mechanical braking preventing the resultant vibration and the noise by a method wherein the current to be supplied for the motor is disconnected simultaneously with the stop order in case the motor is abruptly stopped. CONSTITUTION:When the speed setting up signal 2 is nullified to stop the motor 3, the brake 40 is actuated. At the same time, the positive input terminal potential of the arithmetic amplifier 24 of the stopping current forced disconnecting circuit 23 being nullified, the negative input terminal potential of the arithmetic amplifiers 13, 15 is forcibly turned into the positive potential abruptly nullifying the driving voltage order 12 and the braking voltage 14. When the driving voltage order 12 and the braking voltage order 14 given to the power breaking circuit 22 are nullified, the current to be supplied for the motor 3 is disconnected by said power breaking circuit 22.
