Abstract
PURPOSE: To simplify a control system for obtaining a constant output and stably drive a shunt-wound-field DC motor, by feedbacking the speed signal of the motor to produce a constant torque at the time of slow motion of the motor and control the field system of the motor when its rotational frequency is higher than a predetermined value.
CONSTITUTION: The speed signal VSF generated by a speed signal generator 7 directly coupled to the rotor 2 of the DC motor 1 having a shunt-wound field system 3 is feedbacked. A voltage command amplifier 6 for changing the voltage supplied to the motor and a means 4 for supplying a DC voltage to the rotor 2 are provided to compare the feedbacked speed signal with a speed command signal VS to reduce the difference between them. A difference amplifier 12 reduces a direct current applied to the shunt-wound field winding 3 depending on the difference and a voltage instructing amplifier 9 instructs the output voltage of a DC voltage supply means 8 when the feedbacked signal VSF has exceeded a predetermined value VF. Thus, the control system is simplified and the motor is stably driven.
