​5 Factors to Consider Before Choosing an AC Alternator [Infographic]

30th Jan 2020

An alternator — sometimes called a generator end — is a generator component that converts mechanical energy into electrical power. Alternating current (AC) is standard for homes and buildings around the world.

How do AC Alternators Work?

An AC alternator generates alternating current using a rotating magnetic field with a stationary armature of commutators and brushes. The alternator periodically reverses because the current changes direction. Direct current (DC) generators flow only in one direction.

AC alternators are simpler than DC generators, reducing the wear and tear on its parts. Generating alternating current and delivering it long distances is much easier than delivering direct current. Also, AC voltage can be converted up or down using transformers.

Need Help Selecting the Right AC Alternator?

Before choosing an alternator for your generator, you should consider five factors:

  • Frequency
  • Power rating
  • Poles
  • Phases
  • Voltage

The infographic below expands on these five factors. Check it out to learn more about each. Of course, to build the perfect generator for your power needs, your best bet is to talk to a generator expert.
