American Rotary manufacturers premium rotary phase converters right in Wisconsin!

Search All American Rotary Phase Converters

American Rotary phase converters include a lifetime warranty on parts and labor! Phase converters purchased through us are UL Listed and include premium feet for no additional charge.

Rotary phase converters are most commonly used to power three phase equipment when utility 3-phase power is either too costly or not available. They create true three phase power, often more precise than utility-supplied three phase power! Learn more from our blog 'Phase Converters vs. Variable Frequency Drives'.

American Rotary partnered with Baldor Electric to supply their custom-engineered idler/generators. This partnership led to the design of their custom induction generator for phase conversion which reduced inrush current on start-up so drastically that the induction generator was granted a Soft Start rating! 

Our American Rotary product offering includes three main types of rotary phase converters: 

 

AD Series

ADX Series

AI-PAD Series

This series is precise, reliable and powerful. The AD is great for CNC, VFD, rectified and any other voltage sensitive equipment.

    • Provides strong, utility grade 3-phase power
    • Wall mount standard (floor mount kit available)
    • 208-250V standard (480V available as option)
    • Fully programmable MicroSmart controller*
    • Capable of phase synchronization - can be daisy chained together to double, triple, quadruple your power!
    • Indoor
    • Made in the USA
    • Free shipping for 10hp and under models
    • Unbelievably quiet - industry leading for low operating noise

The American Rotary MicroSmart™ Controller is a patent technology which provides precise control of the phase converter. The controller monitors the voltage every 50 milliseconds providing better voltage control, prolonging the life of the converter, handles significantly more load capacity (ADX and AI), and enabling several failsafe features that are only available on American Rotary’s SMART Series™ phase converters. (AD, ADX, and AI units only)

** High inertia and high friction loads including air-compressors, blowers, fans, flywheel & lifting loads can draw up to 6 times FLA (full load amps) for several seconds during start up. The CTR acts as a stabilizer, ensuring consistent voltage and current. CTR allows our ADX and AI phase converters to start your high inertia machinery with ease in about 1/3 the time of a standard phase converter.  (ADX and AI units only)

When sizing your motor load, please look at both the amp and horsepower and go with the larger of the two. There is no harm in oversizing a converter but an undersized one can cause many issues.

Common Conversions:

hp x 2.8 = 3 phase amps

3 phase amps x 1.6 x 1.2 = Single phase amp feed

kw x 1.342 = hp
