Basic Static Phase Converter Sizing Guidelines:
You only need to determine the horsepower range and
choose between heavy-duty and standard-duty when you are sizing a GENTEC
American Rotary Static Phase Converter.
Note: Please call toll free 1-888-743-6832 for sizing
assistance of static phase converters if:
1. The
motor in the equipment is older than 1965, and/or
2. The
motor in the equipment is not a T-frame motor, and/or
3. The
motor in the equipment is made in Taiwan, Italy, or Germany, and/or
4. The
motor has a high efficiency rating (common in Europe).
Note: Static Phase Converters will only run motor loads.
Static phase converters should not be used with CNC
applications, resistive loads (such as ovens and other heaters),
non-motor inductive loads (such as welders and battery chargers), air
conditioners, and are not recommended for use with two-speed motors, or
any load that will require the motor to product more than 2/3HP
(including most pumps, air compressors, blowers,
etc). Please see our selection of rotary
phase converters and
digital phase converters for these
applications, or call toll free 1-888-743-6832 for
assistance.
Note: All switch gear, contactors, and
controls must operate from two lines only.
1. Choose the static phase converter with the
hp range that includes the hp of the motor to be run.
- Unlike a rotary converter, over-sizing the
converter is not necessary and will not work.
- Some of the hp ranges of the static phase
converters overlap. If the equipment is hard starting,
use the larger of the two
converters that still includes the hp of the machine to be run.
2. Choose Heavy-Duty Static Phase Converters if:
- The equipment is started more than 3 times
per hour.
- Instant reversing will be used.
- The motor in the equipment is more than
1700-1800 RPM
- The equipment has a large load to start,
i.e. lathe, planer, wide belt sander, dust collector, etc.
3. Choose Standard-Duty Static Phase Converters if:
- None of the requirements for heavy-duty are
met. When in doubt, use a heavy-duty
static phase converter, or call our 24/7 toll free sales and
technical support line at
1-888-743-6832.
*Delta wound motors can produce up to 50% of
their rated hp.
They are uncommon and usually found in machines from Germany
and Italy. |

- What
are the advantages of American Rotary's Soft-Start phase converter?
American
Rotary's exclusive
motor-integrated solid state soft-start is built directly into the rotary
phase converter generator housing. Achieving
an 83% reduction
in inrush (starting) current, our custom
GENTEC/Baldor
motor generator was granted a Soft-Start rating.
American Rotary phase converters deliver all the power required for
hard starting, heavy duty applications, along with balanced pure sine
wave output and power factor correction for CNC and other voltage
sensitive applications.
- Will I need to buy a
starter for my American Rotary phase converter?
No! Save
money with American Rotary
phase converters with built-in motor starter and automatic
controls. The rotary phase converter will start automatically
at the touch of the "START" button and is conveniently
pre-wired for remote start and time delay. There is no need to
buy an external starter.
- Are American Rotary
phase converters automatic control ready?
Yes! Timing function available for
automatic controls.
- What about CNC Phase
Converters for CNC and other voltage sensitive equipment?
All American Rotary phase converters are designed to operate CNC and
other voltage sensitive equipment. Our selection of CNC
rotary phase converters
are balanced under load and no-load conditions
to meet the requirements of CNC and other voltage sensitive
equipment. Our phase
converters are balanced under load and no-load conditions to better
than +/-5%. American Rotary's soft-start phase converter
generators are manufactured with ISR (Inverter Spike Resistant) magnet
wire. The development and use of ISR magnet wire virtually
eliminates the spikes that are common in CNC applications.
- Are American Rotary
phase converters power factor corrected, and why is it important?
Yes. Power
factor correction keeps the amount of current that the power company
has to produce to power the rotary phase converter to a minimum,
making our rotary phase converters less expensive to run in
industrial areas where "real power" demand charges can
occur. American Rotary
phase converters utilize our own proprietary soft-start generator,
which typically eliminates demand charges.
- Can
American Rotary phase converters handle heavy-duty and hard-starting
loads?
Yes! American
Rotary phase converters are rated "Heavy-Duty",
which make them ideal for instant motor reversing, tapping, and
other heavily loaded and hard starting applications.
- Why do American
Rotary phase converters have PowerGuardTM Protection?
GENTEC's PowerGuardTM
technology keeps the rotary phase converter and other equipment downstream from
the phase converter from restarting when power
is restored after a brownout or blackout. This feature can be turned off for equipment that
is wired to automatically start after the rotary phase converter.
- Do American Rotary
phase converters have flexible mounting options?
Yes! American Rotary phase converter generators can be mounted in a separate room
or structure away from the rotary phase converter control panel, if
desired. The phase converter control panel can also be conveniently mounted
alongside existing service. American
Rotary phase converters are designed with a
variety of mounting options to best suit the area they serve.
- Will American Rotary
phase converters dim my neighbors lights?
No! American Rotary's custom soft-start phase converter
generators reduce inrush current by 83%!
|
- Is installing
rotary phase converters from American Rotary easy?
Yes! Busbars
are easily accessible and safely located in a roomy compartment just
beneath the firewall. This simple design eliminates messy
wiring and cluttered conduit boxes commonly found in rotary phase
converters. Each and every American Rotary phase
converter is shipped with a complete instruction and installation manual.
There is also a step-by-step installation pictorial available on our
website as well as 24/7 toll free technical support.
- Does American Rotary
manufacture or distribute UL Listed Phase
Converters?
Yes!
American Rotary offers GENTEC
UL
Listed phase converters as well as digital Phase
Perfect phase converters.
UL Listed phase converters are often
indicated in new construction. Please visit our online
store for selection, or call toll free 1-888-7GENTEC.
- Is
there an emergency
stop on American Rotary phase
converters?
Yes.
For
operational safety, when the rotary phase converter is powered on and the LED is
illuminated, the "STOP" button is raised for emergency and quick shut-off.
- Will American Rotary
phase converters run multiple motor loads?
Yes. American
Rotary phase converters are capable of running multiple motor loads
which can exceed 3 X's the rated horsepower of the converter ( limited only by the current
available). Many customers buy larger rotary
phase converters than they currently need in anticipation of adding
additional equipment to their shop and/or business.
- Can I run a very small
machine on a very large American Rotary phase converter?
Absolutely. Because all
American Rotary phase converters are balanced from a no-load
condition, there is no minimum to the size of a motor that can
safely be run with any of our
rotary phase converters.
- Please define
American Rotary's
phase converter efficiency and operating cost.
GENTEC
American Rotary phase converters are very efficient. We define
efficiency in terms of "real power" consumption, or more
importantly, what the power company charges. The national
average is $.08/kWhour. American Rotary's published "Idle
Power" reflects this power. Simply measuring the current
will not reflect an accurate current because of the reactive (or
recirculating) current in the phase converter system. Our data
has been obtained by actual meter tests and should be accurate for
most power company meters. Please refer to the following
equation and example:
-
How
does American Rotary calculate phase converter efficiency?
Cost
To Run/hr =
Real Power (kW) x ($/kWhour)
Example: American Rotary
10HP Soft-Start CNC Balanced/All Purpose Rotary Phase Converters
Idle
Power = .89kW (unbalanced would nearly double to 1.4kW!)
Cost To
Run = .89kW x $.08/kWhour = $.07/hour at idle.
Note: When machine
loads are applied to rotary phase converters, the idle power shifts
slightly, but is considered insignificant.
-
Are
American Rotary phase converters loud?
American Rotary phase converters are extremely quiet! The
bearing noise (friction) common in motors manufactured in China is
virtually eliminated by utilizing precision high-speed bearings and
phase converter generators manufactured entirely in the United
States. Mechanical noise (vibration) is virtually eliminated
with proper mounting of the rotary phase converter and rubber
isolation mounts. Electromagnetic noise (humming or buzzing) is
eliminated by strictly balancing the currents and voltages of the
phase converter. Aerodynamic noise (whirring), common in TEFC
stock motors, is greatly reduced by the extremely efficient
motor-cooling method used by our custom phase converter
generators. Learn more

General
Use Information about American Rotary Phase Converters: |
- What are rotary
phase converters?
Rotary phase converters are electrical devices used to converter single phase
power to three phase power for the purpose of running 3-phase
equipment at or near 100% of its rated horsepower.
- What are static phase
converters?
Static
phase converters
simply act as a means to start an electric motor. Once
that motor has been started, the static phase converter disengages -
leaving the electric motor to run on single-phase power. The
power is unbalanced and though it does work, the equipment can
only operate up to about two-thirds the rated horsepower before
forcing too much current through the motor windings.
The unbalanced output and "single-phasing" of a 3-phase
motor is hard on 3-phase equipment and may shorten the life of the
motor itself. While fine to use in some applications, static phase
converters are inefficient and tend to be hard on 3-phase equipment
and therefore, their use is limited.
- Phase
Perfect® phase converters?
Digital
solid-state phase converters, or simply, digital phase converters are
the ultimate in phase converter technology. Phase
Perfect®
has led the industry in this technology by monitoring the phase
conversion process by using a digital signal
processor (DSP) and then continually adjusting the input and output of
the converter to maintain a perfectly balanced power condition under
all load conditions. Learn

- Who Can Use Phase
Converters?
Phase
converters are most commonly used in home, hobby, commercial, or
industrial settings where utility 3-phase power is not available, or
is too expensive to install or use. Phase converters convert
single-phase power into three-phase power. Phase converters are a very
cost-effective way to power three-phase electric motors, and they come
with simple and easy to use installation manuals. Phase converters are
rated using the maximum horsepower that they can handle. A true phase
converter supplies an electrical current in all three phases of
operation of an electric motor. Due to the consistent energy flow, the
electric motor will operate at or near its full horsepower capacity.

GENERAL INFORMATION ABOUT STATIC PHASE CONVERTERS: |
What are static phase converters?
A static phase converter is simply a starting circuit, or motor starter.
Once the 3-phase motor starts, the static phase converter
disengages and leaves the 3-phase motor to run on single-phase power.
There are several advantages as well as a few disadvantages to this
method of phase conversion.
Why would I use a static phase converter?
Static phase
converters provide the least expensive way to attain generally good
phase conversion for most machine tools.
There is no change to the motor speed.
All switch gear will operate normally, motors will instant reverse, and
motor speed is not changed.
What are the disadvantages of static phase converters?
The primary disadvantages of using a static phase converter are 1) the
motor winding currents will be very unbalanced, and 2) the motor will
only operate at about two-thirds its rated horsepower.
When balanced voltage is desired and/or required, a rotary phase
converter or digital phase converter is indicated.
There are two basic categories of traditional phase converters – rotary
and static phase converters. Rotary, as well as static phase converters
are used to convert single-phase power to three-phase power. A
phase converter is necessary to run commercial or industrial grade
equipment, tools or electric motors that require three-phase power when
only single phase power is available.. However, there are several key
differences between rotary and static phase converters in the methods
these phase converters use and their ultimate reliability.
A static phase converter simply acts as a means to start an electric
motor. Once that motor is started, a static phase converter
disengages - leaving the electric motor to run on single-phase power.
The equipment can only operate up to about two-thirds the rated
horsepower without forcing too much current through the motor windings.
Static phase converters tend to be hard on 3-phase equipment and
therefore, their use is limited. They are not be the best choice
for many applications. For example, static phase converters should
not be used with CNC equipment, resistive loads (such as welders),
pumps, air compressors, inductive loads (such as ovens and heaters), air
conditioners, and are not recommended for use with two-speed motors.
On the other hand, a balanced rotary phase converter allows an electric
motor to operate at or near full capacity. The
rotary phase converter supplies an electrical current in all three
phases of an electric motor’s operation and so provides a consistent
flow of energy. In this way and others, a rotary type is preferred
over a static phase converter.
If quick and easy setup is important and the loss of power isn’t an issue,
a static phase converter may be an appropriate selection for your
application; however, if your application requires a constant current
and full horse power,
rotary
phase converters are still quite easy to install and a better
choice.
