AC Variable Frequency Drives - The
AC Variable Frequency Drive market is huge, due to the great
advances in highly reliable AC power electronics and high power
microprocessors. The advantages to variable frequency
drives are a reduction in greenhouse
gas emissions which translates into saving costs,
the soft start eliminates voltage dips and reduces
starting shock on motor, coupling and gears, the reduced speed
reduces the wear on all drive train components, reduces the need
for high maintenance items such as dampers, and throttling
valves, the likelihood of surges and vibration is reduced and
the 2-pole motor can be done without the use of gearing when the
operating speeds are in excess of 3000 rpm. Variable
frequency drives can be divided into constant torque loads and
constant horsepower loads.

"Phase Converters"
- VFDs, also known as variable frequency drives can
be used to control motor only type of loads. They cannot be used
for any type of non-motor 3 phase load. Find out more about VFD
Phase Converters from the US Phase Converter Standards
Organization website.

phase converter has its disadvantages.
Electric Motors - Electric motors convert electrical
energy into kinetic energy. Electric motors have rotating coils
of wire which are operated by the magnetic force exerted by a
magnetic field on an electric current.
