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 as well as very large or heavily...all with just one phase converter.

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.

Innovation

American Rotary has a 20+ year history of providing innovative technology and design, making our three phase converters more durable, reliable and precise than competitors. We are committed to continuing to introduce features and advances to improve our product to meet your needs.

Testimonial

Keith Hansen, Owner / Jefferson State Machining
--Machining

When we were looking to purchase a rotary phase converter for our shop we noticed a lot of price differences. Having bought cheaper items in the past, we knew all too well of quality and support issues down the road. Therefore we choose to purchase from American Rotary. American quality and American support. We are in our seven year of usage without a problem until we recently relocated the system to accommodate some new machinery. Due to our error, the converter wasn't working properly. A quick call to Chris at American Rotary and within a couple minutes, he directed us which lead to the discovery of our installation mistake. Within minutes, the entire system was up and running. No service calls, no fee's, just great help. A+ company.
