Power Your Shop the Right Way
When you've got serious tools that need three-phase power but you're stuck with single-phase service, American Rotary has your back. We engineer rotary phase converters from compact 5HP units to heavy-duty 300HP industrial converters.
Smart Tech That Works
Our SMART-Series converters feature MicroSmart™ Controllers that monitor voltage every millisecond, delivering rock-solid output even when firing up hard-starting equipment like compressors and pumps. No more voltage drops killing productivity.
The AI-Series units are built tough with rugged Type 3R enclosures, premium Baldor idler generators, and practical features like forklift bases.
Beyond Just Hardware
We help you get it right with expert sizing, real application guidance, and warranties that mean something. Our Wisconsin team understands that when your equipment's down, you're losing money.
American Rotary – Powering the American Dream.
I recently purchase a paint booth for my personal shop and needed three phase for the fans. Lots of talking and research led me to American Rotary. Made the call, Lenny was super helpful with sizing requirements. Made the purchase and received the converter sooner than expected. Installed it that weekend and now my new to me paint booth is up and running. Couldn't be happier with it!

Great experience working with David! He helped me choose the right phase converter and transformer for the job! Shipping was fast and packaged very well. Highly recommend!

The good news is- the 3-phase converter works and it was reasonably priced. I would buy it again. The less good news is the flimsiness of the housing. I have mine mounted on top of the motor and you would expect it to be a lot stiffer and stronger than it is. Also, the assembly instructions have hiccups and I came up short of four nuts.

My ADX 20 has been up and running for 2 weeks now, I love it.
My 15 year old 15hp (not an American Rotary) failed and put me down for several days so you’ll be seeing another order from me for another ADX 20 for redundancy.
I own an industrial laundry renting restaurant linens and can’t afford to be down, not even for several hours let alone several days. My washers are all 10hp VFD motors and I’m upgrading a couple to 15hp VFDs and the soft start only draws 2-3 amps. It’s a beautiful thing watching the amp meter as these giant machines start and stop their motors every 30 seconds and my ADX 20 handles the load effortlessly.
