Abstract

PURPOSE:To avoid driving of a motor at the resonance speed at the resonance point of a pulsating torque by supplying a motor speed signal to an automatic speed controller when the speed signal is matched with the resonance speed of the motor at the resonance point of the pulsating torque. CONSTITUTION:An automatic speed controller 16 adjusts the speed of a motor 10 in accordance with the difference between a speed detection signal NM and a speed setting signal set by a variable speed setting unit 14. In accelerating the speed NM by adjusting the variable speed setting unit 14, when the speed NM becomes the lower limit setting value NL, the contents (NH-NL) of an overspeed range setting unit 26 are supplied to the automatic speed controller 16. In decelerating the speed NM, when the speed NM becomes the upper limit setting value NH, an overspeed range signal is supplied to the controller 16. If the speed NM is varied within the resonance speed range at the time when speed adjustment is not conducted, a signal is supplied from integrator 42 to the automatic speed controller 16.
