Static-Phase Converters
The static-phase converter
was one of the first phase converter used to
convert three-phase power
from a single source for
electric motor loads. The
problem is that
the static-phase converter
does not actually convert
one-phase power to three-phase
power, nor does it generate
three-phase power. The
static-phase converters work by changing and
discharging capacitors to
produce a third-phase of
power only a few seconds
during the startup of
electric motors. If there is
any three-phase circuitry on
your equipment, the static-phase converter will not
properly operate it. It may
start your motor, but you
take a great risk on
damaging the motor or having
motor burnout if you depend
on the static-phase
converter for operating your
equipment.
The reputation of static phase
converters has affected
peoples thinking on what a
phase converter does.
This is one of the reasons
phase converters are not used
more due to the trouble
the static-phase converter
produced in the beginning.
Static-phase converters are known
to reduce the life of your
motor caused by voltage and
current imbalance.
Also, static-phase
converters had harmonics
that pollute the power grid
and damaged equipment.
They don't have the ability to operate
sensitive equipment or
multiple loads. With
manufacturers, such as ACE
and TEMCo, correcting these
problems by inventing quality
rotary-phase converters and
the CNC converters, these
problems were eliminated.
One word of caution,
many companies are calling
their products rotary-phase
converters, but they are
nothing more than a static-phase
converter with a motor.
The static-phase converters are
still used today, and they
work well if you only have
one piece of three-phase
equipment which only
needs 3 phase power for an
electric motor that does not
need to run at full rated
load, or if you are a
small business or homeowner
with a motor or grinder
that needs three-phase power.
One reason why the static
converter seems popular is the
lower cost. Remember,
it will only operate one
machine and the motor will
only receive about 75
percent of
its normal power. Also, by
the nature of its
technology, static-phase
converters use more energy.
Our best recommendation to you
is to talk to a reputable
manufacturer that can help you
in the selection of the right
rotary phase
converter that can do the best job
for your application
requirements. They
will help you select the
right size phase
converter that best suits
your operational needs.
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
