Brushed DC Motors and How to Drive Them detalis.

Image
DC electric motors have been around for nearly two hundred years, with a steady series of refinements in that time. More recently, brushless DC motors have become increasingly popular but for many applications brushed DC motors are still the right choice. Brushed motors are lower cost and are simpler to drive, so they remain a popular option. In this article, we’ll explain the basics of brushed DC motors, and then look at the circuitry required to drive them. We’ll also introduce brushless DC motors and their pros and cons. Brushed DC Motor Basics Going back to basics, the fundamental principle of an electric motor is, of course, that it converts electricity into motion. It does this through the interaction between magnets, one of which is typically created by passing a current through wire bound around a ferrite core.
