Abstract

PURPOSE: To restrict the speed reduction of an induction motor by limiting the braking torque to a specified value by making feedback control of a differentiated quantity of a speed in the case where the excessive torque is generated at the time of low speed of dc braking torque.
CONSTITUTION: The rotation speed of an induction motor 1 is sensed by a speed sensor 10 and differentiated by differentiating circuit 11 and a decceleration (acceleration) torque signal is obtained. Difference between this signal and the maximum value of the DC braking torque of a torque designator 12 is amplified by a torque control amplifier 13 and a current-reference signal is obtained. The current-refernce signal and the output signal of a current sensor 4 are input to a current control amplifier 6 together, and the amplified difference signal is supplied to a power converter 2 through a phase controller 7 to control a DC brake current. The maximum value of the motor current is controlled by a limiter 14 which determines the upper limit of the current reference value. In this constitution, the braking action is applied at the maximum allowable current in the high-speed region, and speed reduction is restricted by the torque designator in the low-speed region.
