Abstract

PURPOSE:To accurately control a torque generated from a motor by correcting a current flowed to the motor in response to the temperature of the motor. CONSTITUTION:A speed command signal Vref from a speed instruction unit 1 is compared by a comparator 2 with a detection speed signal Vfb from a speed detector 4, and the output of the comparator 2 is clamped by a torque command signal from a torque instruction unit 6 to produce a current command signal to a multiplier 14. The multiplier 14 corrects a current command signal output from a clamper 7 by a torque correction signal from a torque correction signal generator 13 and hence a torque signal. A torque correction signal is decided on the basis of a detection signal of a temperature detector 12. Thus, the torque generator from a motor can be accurately controlled irrespective of the temperature of the motor.
