  • We are using the AmericanRotary phase converter to power our 230 volt 3 phase truck tire changers. This allows us to stock 3 phase units and if single phase power is required we simply add the American rotary converter to the package. This system not only works flawlessly but is very simple to install and does not take away from our machine in a cosmetic sense. Their technical support team has been very helpful particularly in helping us choose the correct size unit for our application. I would recommend American Rotary's products and services to anyone.

  • My 3HP Phase Converter was wired in yesterday to my 1-1/2HP Bridgeport J head milling machine. Runs fantastic! I had a friend that is a qualified electrician complete the task. Your included directions were very easy for him to understand and follow. Everything from wiring a new breaker box with the appropriate fuse breakers to powering up the Bridgeport took just under 3 hours. He took a few measurements with his volt meter and stated the mill was running at 98% of peak output efficiency. I'm very pleased needless to say

  • I moved my shop and bought some inexpensive static phase converters for my equipment. Big mistake! One call to American Rotary and all of my problems were solved. The shop is 100% up and running thanks to you guys.

  • For what it's worth, I am pleased with the transaction. Prompt shipment, a follow up phone call, good packaging, and decent instructions. And when we pushed the start button......everything worked. Nice to see another company that has its act together.

  • Bought 10Hp ADX/ Runs 5hp lathe and Bridgeport same time no problem. Quieter than lathe or mill. Installing electrician said best equipment he's seen yet. Great purchase!

  • The phase converter is working perfectly.  It’s much quieter that the previous one, and so far the VSD unit has not skipped a beat so the voltage appears to be nice and clean.  Very happy with your product.

  • The American Rotary Phase Convertor was recommended by a friend. After I purchased it unit online, I received a call from American Rotary checking that I had order the correct size for my equipment. Thanks!

    The installation was simple and straight forward. The idler motor sets on the floor on the other side on the shop under my lathe. The mill runs smoothly with no noticeable power loss.

  • After 8 years of perfect performance from my American Rotary 20 hp converter I burned out the control unit and had to replace it. The fault wasn't the design...I was inadvertently abusing the start caps by "pulsing" my mixer. The box held on for about 4 months before letting go. I called American Rotary for advice and was surprised to get a person on the phone after hours. Despite being stuck at home with an illness, Chris Feavel helped me figure out the most expeditious way to deal with my problem which turned out to be a complete replacement of the control unit. Repair was an option but I didn't have time to wait. The new unit arrived on schedule and was very easy to install. The directions were clear, and it even came with a video. I got stuck at one point due to my lack of skills, but their tech support was superb and I had it running in short order. These folks really stand behind their product and I would enthusiastically buy from American Rotary again
