How Electric Motors Work

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.
