4.6kg 0.13 Sec 22g Mini Digital Servo Metal Gear Corona DS238HV

The rudder is a common name, actually a servo motor. Its working principle is that the control signal enters the signal modulation chip through the channel of the receiver to obtain a DC bias voltage. It has a reference circuit inside, which generates a reference signal with a period of 20ms and a width of 1.5ms. Compare the obtained DC bias voltage with the voltage of the potentiometer to obtain a voltage difference output. Finally, the positive and negative voltage differences are output to the motor driver chip to determine the positive and negative rotation of the motor. When the motor speed is fixed, the cascade reduction gear drives the potentiometer to rotate, so that the voltage difference is 0, and the motor stops rotating.
