how does a dc motor work step by step

The inner workings of a DC motor have been puzzling engineers and inventors for centuries. But how does a DC motor work? This electrical device is easily one of the most powerful and versatile tools that we use today, powering everything from cars to fans. In this article, we'll take a closer look at what makes a DC motor tick and how it works.

DC motors convert electrical energy into mechanical energy, allowing us to do things like drive trains and generate power, just to name a few. By understanding the basics of DC motors, their versatile applications are easier to understand. Let's dive right in and uncover the secrets of how a DC motor works.

The first step to understanding how a DC motor works is to understand its components. A DC motor consists of five main components: the rotor, armature winding, commutator, brushes, and field magnet. The rotor is a metal cylinder with a highly conductive loop of wire. This loop of wire is known as the armature winding and it is powered by an electric current from the commutator. The commutator is a switch that redirects the current from the armature winding. The brushes are two pieces of metal that make contact with the commutator, allowing the current to flow from the armature winding to the field magnet. Finally, the field magnet is made up of permanent magnets that cause the rotor to rotate when electric current passes through it.

These five components work together to create the basic principle of a DC motor - the electromagnetism principle. This principle states that when an electric current passes through a conductor (the armature windings) in a magnetic field (the field magnet), the conductor will be pushed away or pulled towards the magnetic field. When the conductor moves, it creates a circular motion - the rotation of the rotor.
