Motors and armatures are the basic building blocks of modern machines. While you might think of them as simple components, motors and armatures form the core infrastructure that powers so many mechanical processes. From powering industrial equipment to helping cars run smoothly, motors and armatures are essential pieces in any machine. But what is the official business definition for these devices? To understand how motors and armatures work, it’s important to define their terms: A motor is an electrical device that converts energy into mechanical motion. An armature, on the other hand, is a coil of wire wound around an iron core that produces a magnetic field when current flows through it, which directly powers the motor. Together, these two components have revolutionized systems across industries all over the world.
