American Rotary 20 HP Phase Converter

Click here to download AR Series Manual

Now that you have determined that the 20 HP rotary phase converter is the correct size for your application, American Rotary has some exclusive choices for you - ones that you cannot find anywhere else. One of those choices is the controller. To help you choose, here are your options: Mechanical, Digital and ADX Controls:

Mechanical Controls (AR Series): Delivers the voltage balance required for CNC and other voltage-sensitive equipment, and is also advantageous to non-CNC three phase loads. Perfect for standard and heavy duty equipment including CNC, VFD and other voltage sensitive applications

Digital Controls (AD Series): The best performance and protection to the phase converter start circuit and idler/generator, and they allow for increased torque that can be required for extreme starting loads while maintaining precise voltage balancing. If the AR series is like a carbureted engine, the AD series is fuel injected more powerful, reliable, and precise. Runs w/fully programmable MicroSmart controller

ADX Series: In addition to the AD, the ADX series adds nitrous 250 percent more starting power, for compressors, pumps, flywheel loads, etc. w/fully programmable MicroSmart controller. ADX models have current control to provide consistent torque while starting high inertia, extremely hard starting loads, yet are precise enough for CNC applications.

Additional Informatin

This 20HP Rotary Phase Converter changes input single phase power into three phase power, allowing shop equipment to operate at maximum efficiency.  The proper size of a phase converter is determined by the largest load motor to start.  Please call toll free 1-800-458-3687 for sizing assistance and/or our recommendation for your specific application.  This 20HP unit will start and run:

  • Easy Loads up to 15HP: 
    Drills, Mills, Chop Saws, Wheel Balancers, etc.

  • Medium Loads up to 12HP: 
    Routers, Wide Belt Sanders, Radial Arm Saws, Air Compressors, Balers, Drills, etc.

  • Hard Loads up to 10HP: 
    Presses, Punches, Balers, Compressors, Shapers, Shears, Sheet Metal Breaks, Lathes, Sanders, Mixers, etc.

  • CNC and Resistive Loads up to 10HP (28)amps: 
    Milling Machines, Lathes, etc.
