Abstract

PURPOSE:To alleviate a mechanical shock of a DC motor by obtaining the sum of a speed detection signal from the motor and a current limit command applied externally to clamp the command input of a power converter for controlling the rotation of the motor, thereby preventing the abrupt speed variation of the motor. CONSTITUTION:An adder 2 adds a speed command input 1 applied externally and a feedback signal of a tachometer generator 7 coupled to a DC motor 6. The added output is applied through a preamplifier 3 to an adder 4. A level converter 13 allows the output signal of the generator 7 to correspond to the output signal of the amplifier 3 when an armature current is not flowed, and an adder 14 adds the set value of a DC limiting value setter 9 and the output of the converter 13 to operate a current limiter 15. When the motor 6 is rotated with no load, the output signal of the converter 13 and the output of the amplifier 3 are set to the same level. When an external disturbance is applied, the output of the amplifier 3 is clamped by a circuit 15, thereby suppressing the current flowing through the motor 6.
