Motors for Makers: A Guide to Steppers, Servos, and Other Electrical Machines
by Matthew Scarpino

I could compute the Lorentz force in an electric motor, but I had no idea how motor controllers worked in the real world. Put simply, I could write programs and solve equations, but I couldn’t make anything.
Shortly after I received my degree, the first Arduino boards appeared in the marketplace. Their simplicity and low cost sparked a worldwide interest in electronics, and within a few years, the Maker Movement was born. Makers aren’t interested in heavy mathematics and physics. Makers are concerned with what they can ...
