Electric motors are everywhere! In your house, almost every mechanical movement that you see around you is caused by an AC (alternating current) or DC (direct current) electric motor.

A simple motor has six parts:

  • Armature or rotor
  • Commutator
  • Brushes
  • Axle
  • Field magnet
  • DC power supply of some sort

By understanding how a motor works you can learn a lot about magnets, electromagnets and electricity in general. In this article, you will learn what makes electric motors tick.
