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.

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.

Testimonial

Harold Rowlett, /
--Metalworking

Got the American Rotary AR7-UL 7.5 HP phase converter installed and it’s working like a charm. It was so easy to install and to wire. I have another American Rotary 3 HP converter that I purchased over 5 years ago and the improvements you have made to the new units have really simplified the installation and wiring of the units. I have used the 3 HP unit without the first problem and fully expect the new one to perform just as well. These are top notch units and I would recommend them to anyone. They both are being used on metalworking and woodworking machines and are running flawlessly. I have attached a couple of pictures to show how I installed the unit. As you can see in the pic we wall mounted the control box and we put the generator on the other side of the wall in an insulated compressor room. The only problem we had was not being able to hear the generator run which caused us to leave it running overnight a time or two. So I wired in a remote red light and mounted on wall above the control panel (you can see it “on” in the pic) so when we closed the shop we would see the red light on and remember to turn the unit off.

I want to thank you and the staff for being so pleasant to deal with and also the phone calls to follow up before and after the purchase to see if everything was working as it should. Not too many companies have that kind of service anymore. Rest assured if in the future I need more equipment it will be American Rotary.
