What's The Difference Between DC, Servo Stepper Motors?
Servo motors are generally an assembly of four things: a DC motor, a gearing set, a control circuit and a positionsensor (usually a potentiometer). The position of servo motors can be controlled more precisely than those of standard DC motors, and they usually have three wires (power, ground control).
