What is the difference between motor and servo motor?
“DC Motor is a two-wire continuous rotation motor and the two wires are power and ground. When the supply is applied, a DC motor will start rotating until that power is detached. Most of the DC motors run at high revolutions per minute (RPM), examples are; fans being used in computers for cooling or car wheels controlled by a radio.
Servo Motors. Generally, the servo motor is an association of four things, namely a DC motor, a control circuit, a gearing set, and also a potentiometer usually a position sensor. The servo motor position can be controlled more precisely than those of typical DC motors, and generally, they have three wires like power, GND, and control. Power to these motors continually applied, with the servo motor control circuit changing the draw to drive the servo motor.“
