Motors
A well-designed
and well-maintained electric motor can convert over 90% of its input
energy into useful shaft power, 24 hours a day, for decades. The
popularity of motors attests to their effectiveness: they provide
more than four-fifths of the non-vehicular shaft power in the United
States, and use upwards of 60% of the nation's electricity as input.
It is this popularity that makes electric motor systems such an
important potential source of energy savings: because more than
half of all electricity flows through them, even modest improvements
in their design and operation can yield tremendous dividends. A
sizable percentage (15-25%) of U.S. electricity can be saved by
optimizing the performance of electric motors and their associated
wiring, power-conditioning equipment, controls, and transmission
components. These networks of devices are also known as motor systems.
Electric motors are remarkable machines: rugged, reliable, and far
more efficient than the animals and steam-powered equipment that
motors have replaced over the past century.
