Metalworking

American Rotary phase converters are perfectly suited for precision metalworking equipment such as wire EDM’s, CNC lathes, CNC mills, and other voltage-sensitive applications. General Metal Fabrication equipment such as grinders, welders, shears, brakes,and benders, are often run on American Rotary phase converters. When converting from single phase to three phase power, American Rotary phase converters produce balanced 3-phase output to accommodate both very small, lightly loaded machines and very large or heavily loaded machines…all with just one phase converter.

Phase Converter Wizard

When sizing for a Rotary Phase Converter it is best to size with a 2:1 ratio to ensure you will have enough starting capacity. This sizing guideline will protect your equipment long term and ensure it performs at its highest efficiency.

Try out our Phase Converter Wizard by selecting your equipment type and inputting its total HP rating to see which converter series and size would be best for you.

Made & Supported in the USA

Our Phase Converters are made in the USA, using only the highest quality parts. Our Wisconsin-based team includes in-house R&D, engineering, manufacturing, tech support and customer service. We are dedicated to delivering high quality products and great service to our customers.

American Rotary phase converters come with easy to use installation procedures. A step-by-step installation pictorial is available on our website and we have a You Tube video that outlines the ease of installation. In addition, you always have access to our 24/7 toll free technical support.

Built Tough to Last in the Toughest Conditions

Our exclusive integrated soft-start VIT (Variable Impedance Technology) is built directly into the idler/generator and drastically reduces inrush (starting) current. The result is reliable starts, every time, with no voltage drop that can dim your neighbors’ lights.

American Rotary phase converters are rated to run single or multiple motor loads. This capacity is only limited by the single phase current available. Our phase converters are precision balanced from a “no-load” condition so you don’t need to worry about running a small motor together with larger ones using the same phase converter. More importantly, our phase converters can operate with no load engaged for an indefinite period of time, so you don’t have to worry about damaging our units while your equipment loads are not operating. Our engineering department can help determine the right size phase converter for your needs.
