Changing the position of the regulator's carbon brushes keeps the output voltage stable by automatically adjusting the coil turns ratio.
The role of the regulator: regulator is able to automatically adjust the output voltage of the power supply circuit or device. Its role is to fluctuate, can not meet the requirements of the power equipment power supply voltage stabilized in its set value range, so that a variety of circuits or power equipment in the rated operating voltage under normal operation.
The regulator consists of voltage regulating circuit, control circuit, servo motor and other components. Large-capacity regulator also works through the principle of voltage compensation. Choose a regulator that is three times larger than the actual power, because the regulator has to overcome the surge shock of the utility power and the start-up shock of the inductive load in the actual work.
