設けたことを特徴とするサーボモータ駆動回路。 A reversible electric motor 11 that rotates in the forward direction when the forward rotation switch 15 is turned on and rotates in the reverse direction when the reverse rotation switch 16 is turned on; a potentiometer 21 that detects the current position B of the electric motor 11; Detection signal B 1 and motor 1
A comparator circuit 22 compares the command signal A1 indicating the target position A at which the motor 1 should be stopped, and an output signal S1 of the comparator circuit 22 is input, and the difference between the current position B and the target position A is determined at the dead zone level. In a servo motor drive circuit including a switch control circuit 24 that controls the switches 15 and 16 on and off so that the dead zone level is reduced to a range of Δk, the difference between the current position B and the target position A is around the dead zone level Δk. The servo motor drive is characterized by being provided with an intermittent control circuit 28 for intermittent control of the switches 15 and 16 which are in the on state so as to decelerate the reversible electric motor 11 when the deceleration range m near the target position is reached. circuit.
