![]() ![]() For those of you who might not know, electromagnets work by having current flow through wire that is coiled around a “soft” magnet. Rather, stepper motors use electromagnets that are concentrically located around the central shaft to induce it to rotate. As a brushless motor, the central shaft of a stepper motor does not physically touch anything in order to rotate. Stepper motors are one of the three main classes of motors: the other two are DC motors and servo motors. Let’s learn to run a stepper motor! A 4-phase stepper motor rotating the gear. ![]() Unfortunately, there are a lot of people (myself included up until very recently) that wouldn’t know what to do if they were handed a motor and told to run it. ![]() There are motors everywhere in the world around us– in cars, printers, computers, washing machines, electric razors, you name it. ![]()
