American-Made Rotary Phase Converters — Built to Last a Lifetime

Phoenix Phase Converters was founded by Daniel Floreancig, who has spent over five decades engineering, building, and sizing phase converters for every application imaginable. When you call us, you're talking to people who actually understand power conversion — not order-takers reading a script.

Every rotary phase converter we sell is backed by a lifetime warranty. Not 1 year. Not 5 years. Lifetime. We build these units to outlast your equipment, and we stand behind that with the strongest guarantee in the industry.

Our phase converters are designed and manufactured right here in America using domestic components. No overseas sourcing, no corner-cutting, no mystery parts. You get a unit built to American industrial standards.

If our converter doesn't meet your needs, send it back within 90 days for a full refund. We've been doing this long enough to know that almost never happens — but the guarantee is there because we believe in what we build.

Not sure what size you need? Running unusual equipment? Call us at 800-417-6568. We'll walk you through the sizing process and make sure you get the right converter for your application. Free. No pressure.

Phase converters are heavy. We keep shipping simple with flat rate pricing so you know exactly what you're paying before you order. No surprises at checkout.

CNC mills, lathes, and machining centers demand clean, stable three-phase power. Voltage fluctuations and harmonic distortion can ruin finishes, crash tools, and damage VFDs. Our converters deliver balanced power that keeps your spindles running true and your control boards safe.

Wide-belt sanders, shapers, planers, and industrial table saws pull serious amperage on startup. A properly sized rotary phase converter handles these hard-starting loads without voltage drop — so your equipment performs the way it was designed to.

Three-phase welders — MIG, TIG, and stick — deliver smoother arcs and more consistent output than their single-phase counterparts. A rotary phase converter lets you run professional-grade welding equipment anywhere you have single-phase service.

Grain dryers, irrigation pumps, feed mixers, augers, and barn ventilation — farms run on three-phase motors. Rural properties almost never have three-phase utility service. Our converters are the practical, affordable solution that keeps your operation running.

Commercial HVAC compressors, chillers, and rooftop units require three-phase power. Whether you're retrofitting an older building or setting up a new location with only single-phase service, our converters get your climate systems operational.

Hydraulic presses, air compressors, conveyor systems, packaging equipment — if your shop or plant runs three-phase equipment on a single-phase site, we have the converter to handle it. We've sized units for everything from one-man shops to full production facilities.

Give us a call at 800-417-6568 or browse our online store. Tell us what equipment you need to run — motor horsepower, nameplate data, and your application.

We'll recommend the right converter for your specific load. Proper sizing is critical — an undersized converter causes problems, and an oversized one wastes money. We get it right the first time.

Your converter ships quickly with flat rate shipping. Units arrive ready to install. Connect your single-phase input, wire your three-phase equipment, and you're running.

"Converter has been running my Haas VF-2 for three years now without a single issue. Called Phoenix before I bought it — they sized it perfectly and it showed up in four days. Best money I've spent on my shop."

— Jacob T., Machine Shop Owner

"I looked at three different phase converter companies. Phoenix was the only one where I talked to someone who actually understood my setup. The converter runs my entire woodshop — 15HP planer, 10HP wide-belt sander, dust collector — all at the same time. Rock solid."

— Tim W., Custom Woodworker

"Running a 30HP irrigation pump on a farm with single-phase power. The Phoenix converter starts it up without any hesitation, every single time. Five years in and zero problems. The lifetime warranty sealed the deal for me."

— Tad B., Farmer

What size phase converter do I need?

The general rule is to match the converter to your largest motor's horsepower rating. If you're running multiple motors simultaneously, you may need a larger unit. The best approach: call us at 800-417-6568 with your equipment specs and we'll size it correctly — no charge.

Can a rotary phase converter run a CNC machine?

Yes. Rotary phase converters are the preferred solution for CNC mills, lathes, and machining centers. They produce clean, balanced three-phase power that won't damage sensitive electronics or VFDs. We've powered thousands of CNC setups across the country.

What's the difference between a rotary and static phase converter?

A static converter only provides three-phase power for starting a motor — it can't run the motor at full rated horsepower, and it can't power CNC controls or other sensitive electronics. A rotary phase converter generates true three-phase power continuously, handles full loads, and works with any three-phase equipment.

Do you ship nationwide?

Yes. We ship to all 50 states with flat rate shipping. Most orders ship within a few business days.
