A rotary phase converter is a handy device that will allow you to run your three-phase equipment on existing 220V single-phase power.

1. Run your three-phase equipment on single-phase outlet!
If you have any three-phase tool or equipment (such as a woodworking lathe, pump, welder, drill press, grain dryer, etc.), it will NOT run on your existing 220-volt electrical power. A rotary phase converter is a device that will convert your 220V single-phase power to three-phase. (For a sample list of some of the three-phase equipment that you can run on a rotary phase converter, click here.)

2. Three-phase not available in your area!
Often you will find that three-phase power may not even be available in your area, which leaves you with no alternative but to use a rotary phase converter.

3. Get it faster and cheaper!
Your local utility company normally takes much longer (from weeks to months) and charges much, much more to run a three-phase line. Therefore, buying a rotary phase converter is often FASTER and CHEAPER than dealing with the utility company.

Jim Davis got into the rotary phase converter business when the local utility company wanted to charge $27,000 and take several months to run a three-phase line a mere 100 yards to his shop!

A rotary phase converter runs your three-phase equipment continuously on existing single-phase power (220V). A static converter will start three-phase equipment and therefore can be useful when used with the appropriate device, but it will not run three-phase equipment continuously. Some American-made motors can be started with a static converter, but will then run at a lower power output. (For more information, call toll free 1-800-454-6555.)

A CNC converter provides balanced voltage for computer-operated, voltage-sensitive machines.

Yes, but because of how foreign motors are made, you will need to order a rotary phase converter that is one size larger than you would need for an American-built motor. For example, if you have a 2 HP Chinese or Taiwanese motor, you should order our 3 HP rotary phase converter. Foreign motors require greater amperage for start-up than American motors, so you would need a bigger converter.

We make capacitor start/capacitor run induction motors (480V, 10- 200 HP; or 240V, 15-50 HP), which combine the very best features of other types of single-phase motors: They have a high starting torque, high overload torque, and higher efficiency, meaning they operate at a lower temperature than other types of single-phase motors of the same horsepower. You’ll note we also offer larger sizes of single-phase motors (up to 200 HP) than you’re likely to find anywhere else. For more information, please click here. 

Single-phase induction motors are just about the most common type of motor out there, and they’ll run just about anything you can think of on your farm or in your industry. They are especially valuable for agricultural applications (irrigation systems, deep well pumps) and for any application using portable equipment, such as cement mixers and portable conveyors.
