About Three-Phase Power.

Reliable Three-Phase Power for Industrial Equipment

Whether you are powering one critical machine or expanding capacity across your facility, American Rotary provides a dependable path to three-phase power.

Industrial Equipment We Power

American Rotary phase converters allow industrial facilities to run three-phase machinery from single-phase service without costly utility upgrades or demand charges. Our phase converters are used across a wide range of industrial and mixed-use applications.

Filling machines, sealing machines, labeling systems, sorting and inspection equipment, industrial mixers and processors

PLC-controlled production lines, automated assembly systems, robotics and motion control systems, control panels and integrated systems

Rotary screw air compressors, piston air compressors, vacuum pumps, centralized air systems

Centrifugal pumps, submersible pumps, industrial fans, high-volume blowers

Overhead cranes, chain hoists, electric hoists, lifting systems and winches

Belt conveyors, roller conveyors, screw conveyors, automated material handling systems

Problems

The Power Challenges Industrial Facilities Face

Many industrial operations do not have access to utility-provided threephase power, or face high costs and delays to install it. Running industrial equipment on inadequate or unstable power introduces serious risk.

High cost and long timelines to bring in utility three-phase service

Utility upgrades can cost thousands, delay projects, and lock you into ongoing demand charges.

Voltage-sensitive equipment at risk from poor or unstable power

PLCs, CNC controls, and electronics can fault, reset, or fail when power is unbalanced or noisy.

Power surges and utility interruptions that damage equipment

Sudden spikes or outages can destroy rectifiers, drives, and control components.

Difficulty starting high-inertia motors and large industrial loads

Compressors, pumps, cranes, and heavy machinery may struggle to start or trip protection devices, leading to downtime.

Industrial FAQs

Get answers about running your machines on clean threephase power.
Can a rotary phase converter power industrial equipment safely?
Yes. American Rotary converters are engineered to deliver clean, balanced three-phase power suitable for industrial machines, PLC-controlled systems, and sensitive electronics.
In many cases, yes. Proper sizing depends on total horsepower, starting characteristics, and whether machines run simultaneously. Our engineers can help size a system correctly.
Yes. American Rotary offers series designed specifically for high-inertia and hard-starting loads, providing reliable starts without excessive voltage drop.
Our converters use digital controls, custom generators, and built-in protection features to help guard against voltage imbalance, surges, and utility interruptions.
Most converters ship the same day from our Wisconsin facility, helping minimize downtime when power is critical.
Many customers install their converters using our manuals and videos, but working with a licensed electrician is recommended for industrial environments.
