About us

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.
