How Generators Work

What is a Generator?

A generator is a piece of equipment that temporarily provides electricity when it is not available. Generators come in various sizes and range from being able to power just a small television or microwave to being able to power an entire business.


  • Portable Generators
  • Standby Generators

Main Components:

  • Engine
  • Alternator
  • Voltage Regulator
  • Control Panel
  • Permanent Magnet (Stator)

How it works:

  • The engine is started and powered by gasoline (or other fuels in some cases)
  • The armature inside the generator uses a residual magnetic charge to begin rotating
  • The armature keeps increasing in speed, being pushed by the magnetic field of the permanent magnet.
  • As speed increases so does the magnetic field
  • Once at a steady speed the spinning levels out and remains consistent
  • Energy is generated by the spinning and it travels through insulated wires to create an electrical output to power your appliances
