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.

Types:

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

Maintenance Tips:

Be sure to check the recommended maintenance schedule located in your owner’s manual, and to consistently inspect and maintain your generator
Tune up your generator for storm season
