AC Motors - 1-Phase

Single-phase AC motors are as ubiquitous as they are useful -- serving as the prime power sources for a seemingly limitless array of small-horsepower applications in industry and in the home. Knowing how to apply the various types is the key to successful design.

Where three-phase power is unavailable or impractical, it's single-phase motors to the rescue. Though they lack the higher efficiencies of their three-phase siblings, single-phase motors -- correctly sized and rated -- can last a lifetime with little maintenance.
