Three Phase Alternator: What You Need To Know

A three-phase alternator is a type of electrical alternator that uses three rotating magnetic fields to generate electricity. This type of generator is most commonly used in large industrial applications.

Factors to consider when buying a three-phase alternator

When shopping for a three-phase alternator, there are a few factors to consider. Even though three-phase alternators are becoming more common, there are still some things to know before making your purchase. Here are three key considerations:

  1. Output power: The output power of a three-phase alternator is measured in watts. The higher the power, the more electricity your system can generate.
  2. Efficiency: Three-phase alternators are typically more efficient than single-phase alternators. This means they produce more electricity from the same amount of fuel input than single-phase alternators.
  3. Size and weight: Three-phase alternators are larger and heavier than single-phase alternators, which means they will require more space in the engine compartment. They also tend to be more expensive.
