![]() The control of a DC motor using an encoder is not that simple, you just simply can’t start by adding an encoder with the DC Motor and start controlling the DC motor, to use an encoder you will need a controller, the controller will read the encoder and then will accordingly control the DC motor as per the pre-defined instructions written by the programmer. ![]() Then you can stop the DC motor at the position where you want it to stop. With an encoder being added, you can keep track of the motor revolutions, the amount of distance it has covered, and this way you can make a nice feedback system that can be used to control the DC motor. You can’t 100% control a DC motor like Stepper motor and Servo, but if you add an encoder it can really change the whole game. On the other hand, when a dc motor is powered up it immediately starts rotating, it continuously rotates, you can’t exactly control its position until you use a specific technique. Likewise, in stepper motors, you can control the steps precisely and this is the reason stepper motors are used in CNC machines, 3d printers, etc. Servos can move from 0 to 180 degrees, so you can move to any position between 0 and 180. We can control the steps in the forward and reverse directions. ![]() The stepper motors and servo motors are designed in a way that we can control their position. These three types of motors have a different construction. If you have watched my videos and read my articles then you should know DC motors are quite different from Stepper Motors and servo Motors. DC motors are more frequently used than Stepper Motors and Servo Motors.
