Abstract

PURPOSE:To sufficiently maintain a predetermined speed ratio of a plurality of motors even when the speeds of the motors are varied by inputting a signal from an acceleration and deceleration calculator to a differentiating circuit and applying the output of the circuit to each speed controller provided with additional input circuit. CONSTITUTION:A number of motors M are energized from anti-parallel thyristor converters Rec and are controlled by a current loop having a current controller ACR and a speed loop having a speed controller ASR. The target value of the speed controller ASR is introduced through a setting potentiometer SP and an acceleration and deceleration speed calculator HLR from each ration setting unit DR, and a signal through the differentiating circuit D from the calculator HLR is applied through an adjustable voltage divider VR2 to the additional input circuit 1 of the speed controller ASR. Consequently, a compensation signal corresponding to the necessary acceleration and deceleration torque can be applied to each motor M, and the speed ratio can be preferably maintained.
