The Phase Converter
Manufacturer Directory
Rotary-Phase Converters
Because of the
increase in three-phase
machinery in our industrial
field, rotary-phase
converters have become
high in demand. Some companies have
started manufacturing
phase converters, and sadly
to say, are trying to sell
sub-standard phase
converters or are selling a
static-phase converter with
a motor. One of the reasons
for this is there are no
regulations on phase
converters as yet.
Quality phase converters use a
balanced three-phase
generator with power factor
correction components. They
are made with high quality
materials such as copper
windings and other quality parts.
When properly installed, a
quality rotary-phase
converter should operate
indefinitely, 35 years and
more. When searching for a
phase converter, a quality
manufacturer should have a
warranty of at least five years
or longer. If they cannot
offer a long-term warranty,
it is best to select a more
reputable manufacturer,
which would insure a better
quality phase converter.
In our research, we found that
the output of electricity is
a smooth, balanced
three-phase waveform that is
dependable and safe for
machinery when using a true
rotary-phase converter with
a three-phase generator with
power correction. Rotary-phase converters are
used for many different
types of machinery such as
welders, drill presses, CNC
equipment, grain dryers,
farm equipment, just to name
a few. Any time you have a
piece of equipment that
needs three-phase power and
has only a single-phase
power source to run on, a
rotary-phase converter is
the best
cost-effective solution.
Another important factor is
making sure you get the
right size. Ninety percent of
problems with phase
converters are due to the
fact that they are not the
right size for the
application. Rotary-phase
converters are usually sized
larger than the power needed. Remember, a properly sized
and correct type of phase
converter will give you
years of trouble-free
service and operate your
equipment as well as a
utility three-phase
installation. When
purchasing a phase
converter, always take into
consideration that your
machinery may be hard to start,
that you may have more than one
piece of equipment needing
startup, and that your
equipment starts at the
same time or at different
times. Any quality
manufacturer should be
asking these questions in
order to help you find the correct
converter for your
application.
One of the reasons rotary-phase
converters have become so
popular is basically
economics. Utility companies
usually supply single-phase
power to homes and businesses
when utility three-phase
power is unavailable (such
as in rural areas), or the cost
of utility three-phase power
does not justify its
installation. Construction
of three-phase power lines
can cost as much as $50,000
per mile, and the time it
takes to provide three-phase
power from utilities can
cause downtime for
businesses.
The following chart compares
each manufacturer based on a phase
converter for a
10HP motor. We rated each
company with a one to five
star rating, five stars being the highest
and one star the
lowest.
*Compared models that use active generators
and found that they are higher
quality - this rating is not
for lesser quality converters
using electric motors.
Also, models rated on the materials
used to manufacturer the
phase converters.

ratings are determined.
In
our findings,
ACE
Phase Converters
rated the highest because
they manufacturer a true
three-phase converter. Their phase converters were
durable and manufactured
with high quality materials,
and their ten-year warranties
on their products were
outstanding. Pricing was
excellent comparably in the
market place. Great Phase Converter Articles
