How do model servos work?

Model servos are small devices that are essential for controlling all types of remote-controlled vehicles, from planes and helicopters to cars and boats. They are essentially small motors that are combined with a circuit board, a gear train, and a potentiometer to produce a precise and controlled movement.

The way in which model servos work is relatively straightforward. When an electrical signal is sent to the servo, it activates the motor, which turns a small gear. This gear is connected to a larger gear, which in turn engages the output shaft of the servo. As the motor turns the gear, the output shaft rotates as well, providing precise angular control.

To provide precise angular control, model servos incorporate a potentiometer. This is a variable resistor that moves in proportion to the angle of rotation of the output shaft. The rotation of the potentiometer is detected by the servo’s circuit board, which feedback to the controller of the remote-controlled vehicle This enables the controller to adjust the position of the output shaft to within a very small tolerance, making model servos ideal for both precision and control.

Overall, model servos are small but incredibly powerful gadgets that are essential for remote-controlled vehicles. Whether you are flying a plane or racing a car, you can benefit from the precision and control that these devices provide.
