About :
Unitra G602 stabilization/speed control circuit works like this = the signal level is constant, and the frequency changes slightly. Then it is amplified to a meander and through a throttle capacitor, goes to a diode detector, where it is doubled again. Then the RC chain smooths slightly, it serves as a speed monitor (selected for smooth running and quick response), R simultaneously serves as an H pull-up for the differential stage on PNP transistors, and if there is no signal, the speed is maximum. It charges the capacitor with voltage, thereby reducing the gain, since the differential stage on PNP transistors creates the effect of weight scales: the higher the voltage at the input, the lower the output. (electronic brake) Everywhere has its own sensitivity and hysteresis. the creators wanted to get rid of or reduce the noise and vibration (14-15Hz 880-900-rpm electric motor, at-33.33rpm) created by the electric motor and reduced U and I to a minimum, this became a strong dependence on everything.
