most common type of phase converter is the Rotary
Phase Converter. Not all Rotary
Phase Converters are the same. Many just
convert single phase power into unbalanced 3 phase
power, while the best kind that we were able to find
will actually generate true balanced 3 phase power.
This is the best kind to use. There were only
a few companies who manufacture this type with the
most notable two brands being TEMCo
Phase Converters and ACE
PHASE CONVERTERS. A few other companies
called this type of 3 phase generating rotary phase
converter a motor
duty rotary phase converters generate high quality 3
phase power while running on single phase. Rotary
Phase Converters are being used throughout the US and
internationally every day. Their quality 3 phase power
will run any 3 phase application. 3 phase applications
range from 3
phase computers, 3
phase pumps, 3
phase welders, 3
phase ovens, to 3
phase CNC mills, etc.
Phase Converters Cost Less Than Utility Three Phase
it comes to powering three phase electric motors and
machines of all types, often three phase power from a
utility company is expensive or not even available.
Single phase power is more often available at a
reasonable rate. Quality brands of heavy duty rotary
phase converters are efficient at generating the
necessary three phase power from single phase. They
provide full rated balanced three phase power for any
three phase application.
Phase Converters Provide Reliable,
Balanced, and Efficient Three Phase Power
duty rotary phase converters are built to last with
quality precision rotors and long lasting components
to give 3 phase electrical power service you can count
on. Quality rotary converters are reliable and
efficient at generating three phase power - even
better quality 3 phase than utility supplied power.
Be sure to note the difference between a quality
rotary phase converter and a
static phase converter.

high quality 3 phase power.
are many different kinds of electric motors and
machinery built today. Check out a phase
converter sizing guide and call the manufacturer
to choose the correct model to power your three phase
motors or machines.
Phase Converter Ratings
US Phase Converter Standards Organization says that true
3 phase Rotary Phase Converters scored
the highest in all categories of their testing and
are their findings:
3 phase Rotary Phase Converters use a balanced 3 phase
generator with power factor correction, resulting in
balanced safe 3 phase power that is better than even
standard utility supplied 3 phase power.
properly installed, Rotary Phase Converters were safe
to operate. Due to high quality materials such
as copper windings and quality parts, with standard
maintenance, a quality Rotary Phase Converter should
operate indefinitely (35 years and more). There
are tens of thousands of 3 phase generating rotary
phase converters installed in the US that have
operated over 50 years. The balanced 3 phase
generator and power factor correction ensure that the
output is a smooth balanced 3 phase wave form that
will be completely safe for the 3 phase machinery it
is meant to operate.
In the U.S. Phase Converter Standards Organization's
research they found that some companies called a
product that they sold a "Rotary Phase
Converter" but, in fact, their product is made
with just a control box (or a Static
Converter) and an electric motor. These type
of products were shown though their rigorous testing
to be unsafe and unreliable. There is a tendency
for these "Static
Phase Converter" controlled units to burn out
the equipment it is meant to operate due to phase
imbalances that change with the load. They did
not count these types of products as true Rotary Phase
Converters, but rather in the category of Static
Phase Converter or Build

is recommended that only true 3 phase balanced Rotary
Phase Converters, with a 3 phase generator and power
factor correction, are used to power 3 phase machinery

Phase Converter Types and Comparison
old fashioned research will help guide you to make
sure that you are able to get the proper product to
give you balanced 3 phase power. The US
Phase Converter Standards Organization has some
excellent guides to help choose the appropriate
technology for your need comparing them side by side.

strengths and weaknesses of each type side by side
with their ratings on quality, durability, safety, and
