This gives you total control over the motor, allowing you to move it to an exact location and hold that position. Stepper motors can turn an exact amount of degrees (or steps) as desired. How a Stepper Motor Works?Ī regular DC motor spins in only direction whereas a Stepper motor can spin in precise increments. This is where the stepper motors come in handy. Again, that threaded rod needs to be moved an exact amount to print one letter after another. There is another motor attached to a threaded rod that moves the print head back and forth. This motor needs to be able to move the paper an exact distance to be able to print the next line of text or the next line of an image. One such motor acts as the paper feed, spinning rollers that move the piece of paper as ink is being printed on it. There are lots of moving parts inside a printer, including motors. You can vary the speed with the amount of power given to the motor, but you cannot tell the propeller to stop at a specific position. The motor spins very fast in one direction or another. The stepper motor can be controlled with or without feedback.
The Stepper Motors therefore are manufactured with steps per revolution of 12, 24, 72, 144, 180, and 200, resulting in stepping angles of 30, 15, 5, 2.5, 2, and 1.8 degrees per step. Unlike a brushless DC motor, which rotates continuously when a fixed DC voltage is applied to it, a step motor rotates in discrete step angles.

A Stepper Motor or a step motor is a brushless, synchronous motor, which divides a full rotation into a number of steps.
