AC Motors


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.


LEESON'S line of three-phase AC motors are designed to both EPACT and Premium energy-efficiency mandates. They meet the energy efficiency requirements of the United States and Canada for general-purpose industrial motors while delivering new levels of starting torque, overload capability and reliability. We have both ODP and Enclosed designs in frame construction of either rolled steel, Aluminum or Cast Iron and HP ratings of 1/6 HP through 700 HP.
