Abstract

PURPOSE: To obtain the same antihunting effect at all times without depending upon a power-factor by mounting a dividing circuit dividing the control input signals of a phase controller for an inverter by speed setting signals and a differentiation circuit differentiating the output of the dividing circuit and the like.
CONSTITUTION: An arithmetic circuit 20 arithmetically operating the internal magnetic flux of the AC motor 4 and the dividing circuit 23 dividing the control input signals Eα of the phase controller 11 controlling the output voltage of the inverter 3 by the speed setting signals e1 are mounted to the controller for operating the AC motor 4 in a variable-speed manner by means of the inverter 3. The differentiation circuits 18, 24, which differentiate the first signals, internal magnetic flux signals obtained by the arithmetic circuit 20, and the second signals, the result of division acquired by the dividing circuit 23, and output both signals, and means 19, 25 overlapping these differentiation output to the speed setting signals e1 of the inverter 3 are set up.
