Abstract
PURPOSE: To suppress the drift of rotary machines having a simple structure by constituting a discharge circuit which discharges an integration capacitor throuth a resistor when an input switch is turned OFF.
CONSTITUTION: A discharge circuit is constituted by a relay 10 having contacts 10A to 10C which are driven by a switch 5, a resistor 11 which discharges an integtation capacitor 7 by the action of the contacts 10B, and a resistor 12 which decreases the gain of an operation amplifier 6 during the period of discharging of the integration capacitor 7. When input switch 5 is turned OFF, the relay 1 is also turned OFF, and the speed control input is turned OFF. Then, the integration capacitor 7 is isolated from the operational amplifier 6 and discharged throuth the resistor 11. A resistor 12 is connected to the operation amplifier 7, and the gain is decreased. Since the outputs of the operation amplifiers 3 and 6 are made sufficiently small, the drift of the motor can be almost completely suppressed.
