A micro servo motor is a small electric motor specially designed to control movement precisely. It consists of a motor, gearbox, and control circuit, all housed in a compact body. The control circuit monitors the motor's position and adjusts the voltage and current to ensure it moves to the desired position.

When a signal is sent to the micro servo motor, the control circuit compares the signal with the motor position and adjusts the voltage and current accordingly. This will rotate the motor to the desired position. The motor is connected to a series of gears that increase the torque and decrease the speed of the motor, allowing precise control of the movement.
