Abstract

PURPOSE: To quickly return a motor into a control range despite a large disturbance, by connecting the motor in series with a transistor which is regulated by a control signal and coupling a load in parallel with the motor so that the load acts as a mechanical load upon the motor.
CONSTITUTION: The motor 3 is connected in series with the transistor 2, the degree of turn-on of which is regulated by the control signal. The load R4 is coupled parallel with the motor 3. In the stationary operation of the motor, a voltage Vc corresponding to an S-T curve (c) is applied to the motor. When the load fluctuates by -t from a stationary level T, the transistor 2 is turned off and the motor acts as an electricity generator and its rotational frequency is going to rise along the negative part (d') of another curve (d). However, discharge is started and the motor is decelerated because the load R is connected to the motor. At that time, the voltage falls to a level Ve corresponding to another curve (e) and the motor is returned to the stationary loaded state. The servo pull-in property under a negative load is thus greatly improved.
