Abstract

The rotation-speed regulator is provided with a controlled semiconductor (17) in series with the motor, a threshold-value switch (18) in the control loop of the controlled semiconductor (17), and with an RC element (19), having an adjustable time constant, on the input side of the threshold-value switch. In the case of this regulator, the influence of power-supply voltage fluctuations on the rotation speed of the motor is largely eliminated, so that the motor essentially runs at an unchanged rotation speed in the event of variations in the power-supply voltage. For this purpose, the threshold-value switch (18), which is preferably constructed as a programmable unijunction transistor (20), has a threshold value whose magnitude is controllable. A control circuit (21) changes the threshold value as a function of voltage changes in the AC voltage power supply (15).
