Rotary phase converters are most commonly used in commercial, industrial, and residential settings to power three phase equipment when utility 3-phase power is either too costly or not available. Rotary phase converters convert single-phase power into balanced three-phase power. Rotary phase converters are a very cost-effective way to power three-phase CNC equipment, and they come with simple and easy to use installation manuals. Rotary phase converters are rated using the maximum horsepower that they can handle. Due to the consistent voltage balance, the electric motor will operate at or near its full horsepower capacity. The output is custom balanced to meet the requirements of CNC equipment as well as other loads.
A rotary phase converter, by itself, is in an idle state and draws only the amount needed to keep it energized. This is only a few kilowatts and in some cases is less than a kilowatt. Your true electrical consumption is based on what the load draws. The rotary phase converter is merely a device electricity passes through on its way to your load.
Yes, however, a transformer is also needed. A rotary phase converter produces a three phase voltage identical to its input voltage. For example, if your input is 240 volts single phase, then your output is 240 volts three phase. The rotary converter does not change voltages. In this case, a step up 3 phase transformer (240 volt to 480 volt) is needed after the phase converter.
An America Rotary phase converter is very dependable and maintenance free. Bearing grease may occasionally be needed.
Your single phase service required is dependent on the loads connected after the phase converter. America Rotary phase converters will run on a range of input amperage. As a general rule, determine your 3 phase load amps and double for your single phase feeder amps.
Generally speaking, you will need wire, conduit, connectors and a single phase power source, such as a circuit breaker or disconnect switch. More materials may be needed depending on how elaborate your output connection is between the load and phase converter. American Rotary offers a full line of electrical components to make your installation easy, professional, and safe.
CNC stands for Computer Numerical Control. CNC equipment has a computer that can be programmed to run the operation of the machine. Computer operated machines are generally very voltage sensitive. The American Rotary Smart Series Rotary Phase Converter has +/-5% voltage balance to run these types of machines.
Absolutely not, provided the rotary phase converter is sized correctly. Our Micro-Smart controller generates a balanced three phase output allowing your equipment to furnish full rated power.
Most utility companies will recommend the use of a rotary phase converter. In fact, it is much more cost favorable compared to installing 3-phase power lines. With the American Rotary/Baldor induction generator and American Rotary's Variable Impedence Technology (VIT), utility companies prefer the American Rotary converter because it use 1/3 of the current at start up compared to other phase converters.
The truthful answer is no!” The only organizations we are aware of and adhere to are UL (Underwriters Laboratories) and the N.E.C.(National Electric Code) Article 455. These are the organizations and standards that America Phase Converters follows.
In this video, we show the basic installation techniques of the American Rotary Phase Converter Panel. The idea is to show how easy it is to install, and also to provide a video reference for our customers. The video is just under 4 minutes long.

We are using the AmericanRotary phase converter to power our 230 volt 3 phase truck tire changers. This allows us to stock 3 phase units and if single phase power is required we simply add the American rotary converter to the package. This system not only works flawlessly but is very simple to install and does not take away from our machine in a cosmetic sense. Their technical support team has been very helpful particularly in helping us choose the correct size unit for our application. I would recommend American Rotary's products and services to anyone.
