Abstract

PURPOSE:To enhance the reliability of the induction motor control system and to reduce the noise thereof by determining the current caused by field and torque from the load amount and the speed of the motor. CONSTITUTION:There is provided a function generator circuit 27 generating the secondary magnetic flux reference with an operating speed as an input from a speed senser 15. The input and the output relationship of the circuit 27 is suitably defined so that the secondary magnetic flux reference is increased as the speed along a square speed curve to become rated secondary magnetic flux reference at predetermined speed to allow predetermined constant value even if the speed is accelerated over the reference. In this manner it is not considerably affected by the calculation error of the control circuit in low speed range and the secondary magnetic flux is weakened to eliminate the noise.
