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.
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.
