Fantastic product with great customer service. I wouldn’t hesitate to buy from them again.
My old rotary phase converter gave 30 years of faithful service before it went up in smoke. With customers asking when I’d be operational, I researched every manufacturer and the choice was clear on American Rotary.
First impression when it arrived: this is a quality piece of equipment.
When we fired up the mill, it ran noticeably better than our old converter. We’re back to running three machines with capacity for more.
Thank you for building a quality rotary converter that got us back in business.”
Very good company to do business with. The salesman Lenny treated me like I was a big company. I was shopping for a roto phase for my home machine shop. He had all the time in the world for me. From beginning to end. I would highly recommend this company to anyone. Big or small!
A quick google search pointed me toward American Rotary. It wasn’t their website or their pricing but the number of videos and testimonials about the quality of their product and the great service. I wasn’t disappointed.
I called on a late Friday evening hoping to reach someone for some info on their products but what I got was a gentleman who asked probing questions regarding my needs and it was only a matter of a few minutes before I was convinced that I found the right company to put my trust in. Lenny analyzed my needs and sized my converter. I also purchased a load center and breakers — A one stop shop!
I hung up the phone happy on Friday and received my converter about 36 hours later — on a Sunday! and I’m half way across the country! wow. I got to work installing — it was a breeze.
It started right up and runs great — smooth and very quiet. The equipment is very well made — I don’t think I’ll ever have an issue — but if I do, I won’t worry knowing guys like Lenny are out there to take care of me.
I purchased this unit for a tenant in a commercial property that needed 3 phase power and the cost for the utility company to bring it in was significantly higher with much longer times to complete the project.
The phase converter was up and running the day after delivery and works great. Excellent customer service and purchasing experience
I tried an inexpensive digital converter that made my machine motors very hot due to unbalanced power. A person I bought a milling machine from said he had an American Rotary and was very happy with the quality, so I gave them a try.
When the unit arrived, the control box had a shipping dent. I called American Rotary and they sent another one immediately.
The unit works flawlessly, is very quiet, and my equipment motors don’t even get warm.It has been very nice to deal with an honest company that looks out for the best interest of their customers.
When I started, the garage had a single 120 V receptacle behind a shelf. Now, there (4) duplex 120A receptacles, (1) NEMA 16,20 A 240/120V with a DPDT switch to select voltages. 30A 50A 1 phase receptacles. Two 20A, one 30A and one 15A 3phase receptacles with a disconnect from the converter to the 3phase box.
Your converter works perfectly, no issues at all. Thank you Jessica for your help.
I called in a talked to a representative told them I have a refrigeration unit I was looking to run 3 phase to, gave them the specs and was recommended the ADX 10. I ordered it super fast shipping got it home unboxed it.
Myself and my HVAC electrician installed the phase converter very easy and very clean setup. System runs flawless is very quiet.
I am very happy with everything from start to finish thank you American Rotary highly recommend any of your products
I had to move my workshop due to rent increases. The one I found didn’t have 3 phase. I found some cheap crappy digital shifter…didn’t work.
Then I found American Rotary, they are the real deal!
I am able to run my 3 phase radial arm saw and paint booth motor from the same unit.
It’s quiet and efficient.
para todos los hispanohablantes America Rotary 100% recomendado fácil de instalar fácil de manejar fácil de cablear todo perfectamente gracias por su ayuda para poner en funcionamiento mi máquina edgebanding 3 Phase
For all Spanish speakers, American Rotary 100% recommended. easy to install, easy to handle, easy to wire everything perfectly! Thank you for your help in getting my edge banding machine up and running on 3 Phase
Just got my ADX 5 up and running couldn’t be happier with my decision to purchase this excellent customer service and tech support. A++++++
Absolutely love what american rotary does. Had a wonderful experience with their support team the phase converter we purchased and the transformer were supper easy to install definitely recommend buying from them. Customer service is 10/10
American Rotary is an awesome company to work with, Mike was/is very helpful in answering my questions and getting me what I needed to get my shop ready for a new machine, giving me an option to either piggy back my existing American Rotary converter and or getting a new one. My old one has serviced me for several years now so I knew I could trust them with adding a second one to increase my capacity. Thanks American Rotary and Mike.
I have an AMP10 Tier 3 with the ADX upgrade and it is an incredible machine. Mike told me my unit would have to be built to order and would ship ‘tomorrow afternoon.’ That’s exactly when it shipped. Incredible.
The build quality and packaging were both impressive. This is the epitome of American manufacturing, quality products and amazing service.
I’d recommend American Rotary to anyone looking for 3 phase power where it’s not available. I’ll be a user of American Rotary equipment for life.
Our company recently moved into a building that did not have 3 phase power. We contacted our local utility for a quote to upgrade our service to 3 phase. Due to current supply chain issues, we discovered the meter box required for the upgrade had an anticipated delivery of 50 to 60 weeks!
We decided to purchase a rotary phase converter to bridge the gap until our upgrade could be completed. After extensive research, we chose American Rotary. We’re extremely pleased with our decision to purchase an AD60-PM digital phase converter.
We’ve been running 5 pieces of equipment with it including a lathe, surface grinder and three 5-axis mills. We’re able to run multiple items simultaneously, including 400 volt European machines with transformers. We’re seriously considering continuing with our current process and avoiding a very costly 3 phase upgrade. We may just run the entire shop using phase converters.
Our unit is very quiet. Setup was a simple, straight forward, intuitive process. American Rotary products are made in the US. Service is outstanding and the staff is knowledgeable, professional and friendly. We’ll definitely purchase any additional phase converters from American Rotary.
I had a need for 3-phase power for a PLC/CNC encapsulator. This machine is very sensitive to voltage and requires “clean” power. I tried another company’s rotary phase converter and it damaged the rectifiers. I rebuilt the rectifiers and went with American Rotary Phase Converters AMP-20.
Super simple set-up. 1) take it out of the crate. 2) plug it in and read the directions. 3) turn it on and go to work. The is an awesome piece of equipment and it is quiet. I highly recommend this company to you!
I purchased the AD30 from American Rotary about 2 months ago and so far have been extremely pleased. It is extremely quiet, very well built, and best of all, it just runs and works. As a business, I need equipment that I can rely on and trust and I am very happy that I trusted American Rotary. They had it to me within a week of ordering!
Had an electrician come out and wire it in, 100 amp single phase breaker, then 2 guage wire going to the phase converter, the phase converter then feeds a 3 phase sub panel where I have my Haas Super Mini Mill wired into. Voltage is well balanced to within 5% which is what I need to run my CNC Mill. The Mill powers up and runs without any hiccups at all, I can’t even tell it’s being powered off a phase converter. No delay or lag when the spindle starts/stops.
Overall, this phase converter is probably my best piece of equipment that I have as far as not having any hiccups. Extremely pleased and glad I didn’t waste my time with the other brands. Thank you!
I was in a situation of do I spend $45,000 for 3 phase power from the power company or do I buy the AD30.
Well when looking at the numbers it was an obvious choice. I bought the AD30 and could not be happier!
I followed the directions which were spelled out very clearly. I used #3 copper for all my power lines including the grounds. I used a 100amp breaker for my single phase feed. It’s important in my opinion to monitor the 3phases of power coming out of the RPC going to my 3 phase panel.
To do that I purchased the phase monitor contacter. I wanted the ease of pulling the wire easy so I used 1-1/4” metal clad flex tight. The AD30 powers my Fadal VMC15 XT with no problems whatsoever.
The unit is quiet and works flawlessly.
Go with a USA Made American Rotary Phase Converter if you need 3 phase power.
We had a power surge courtesy Energy Power that completely destroyed our 60 Hp American 3 Phase converter on Thursday at 4 PM CST I called the west Coast service line after 4:30 about a replacement and they referred me to the WI office for service with cell phone for a customer service person.
I called and we determined exactly what was needed to bring us back online and additional isolators to protect us in the future from similar problems.
They shipped everything on Friday second day to us and we were up and running by 4PM the following Monday. We have several convertors in our plants but all future replacements will only be American Rotary.
Fantastic service could not ask for more or better service from a company. The unit replaced was 15 years old and they had the replacement parts on the self. I wouldn’t buy any other brand and my electrician says the same.
I could not be happier with my phase convertor my 20hp AD unit is quite and runs my 1941 Monarch 16 x 30 cy as if it was plugged into line service. Great product and great people
When I researched phase converters, two other companies offered me a price without much help choosing the correct one. When I spoke to Ally at American Rotary, she asked lots of questions about my equipment and my shop. The quote she sent included everything I’d need for a complete install.
The directions were simple and clear. I followed the instructions fully and the unit came up on the first try.
Now my equipment is running stronger and I can run two machines simultaneously. I am so pleased with my AR 10 and with the service I received.
I picked up an AR-10 to run my 3phase lathe. Super easy installed and support from the staff when I had questions.
This was an outstanding company to do business with. I wish all companies would emulate their level of customer service.
Jacob Pawley was phenomenal in helping me with any and all questions. Product quality is fantastic and ease of set up was great!
I bought an AD 30 rotary phase converter to run my Milltronics RH30 CNC mill. The unit was easy to install and any troubleshooting questions I had was answered right on the first phone call from your knowledgeable staff. Thanks guys for a great product and the wonderful customer service that stands behind it.
I bought 2 phase converters to power up my waterjet, I love the units, I love the customer service, the units are over 5 years old and still running like day one. Please do yourself and dont try to cut corners like I did.
I initially purchased from Phoenix Phase converters and got ripped off, units did not start up on their own and kept causing my waterjet pump to fault out, to make matters worse that company whom I bought the phase converter kept blaming the electric company.
It was not the electric company it was the phase converter. I decided to call American and they fixed me up, no more problems. I start the phase converters with a big smile on on my face every morning when I start my work. Thank you guys and keep up the super awesome customer service.
Great follow up and engagement. Ally was of great assistance.
Man! I owe you guys big! Thanks to your help my mill finally runs!!!! So happy. Thank you Thank you!
American Rotary rocks!!!
Needed additional 3 phase power. I already had an ADX-20 phase converter but it wasn’t big enough to handle the additional load. I installed another ADX-20 rotary phase converter and it starts the new air compressor no problem. I hooked them in parallel and put phase monitors on the units. I also installed surge suppressors on each phase monitor.
Worked with Jacob at American Rotary and he was great at answering my questions and didn’t get annoyed with my layman’s understanding of electricity.
After a lot of research I decided on American Rotary and specifically the ADX20 to have some room to run everything in my hobby shop. An AR rep answered all my questions and the order process was smooth and pain free.
The freight company cosmetically damaged the panel. I called AR while the delivery driver was there, and they assured me they would help take care of the problem. I accepted the order as damaged and AR had me taken care of the following week.
It’s impressive to work with a company that wants happy customers!!!! Thanks AR for providing a great product and great customer service. The ADX20 is installed and happily powering my 3 phase toys. And yes the Baldor idler is quiet enough that any running tool drowns out the idler running.
Just like to thank Ally and the rest of the folks at American Rotary you make a very nice product with excellent instruction manuals and top of line customer service. I am extremely happy with your equipment it was a breeze to install and I’m amazed how quiet it runs.
It means a lot to me that it’s American made and the cherry on top is it’s here in Wisconsin. I will definitely recommend your company keep up the great work
I am KC Cromwell of Castleton, Virginia. In 2007 I returned from Iraq and opened my own Woos Working Business under my own name. After renting a few buildings, I purchased a home with a large horse stable. I converted the stables into my shop but did not have 3 phase power.
American Rotary, with the help of Mr. Feavel, set me up with a unit that would meet my needs. I have a lot of large equipment, so it took some time to figure out what I needed.
The electrician installed the unit is less than a day and I was up and running. I surprised at first at the size of the unit, not having any background in this profession. More importantly, the unit is surprising quite and runs very smoothly.
I know now that if I need anything related I can contact American Rotary and get good advice. good pricing and great service.
I was hesitant to spend the extra money over other phase converters I was looking at, but you pay for what you get. The idler motors are so quiet you can’t even hear them run while your machine is going.
I purchased the 3 phase load center with the ADX10 to run multiple machines off the same converter, which is definitely the way to go.
Customer support is second to none, the best I’ve had in a long time.
I AM A VERY HAPPY CUSTOMER and will recommend them whenever possible. Remember, you get what you pay for.
This is a great product from a great company. Between ordering info and tech support, I had no problems figuring out how to do the hookup and install of my AD05 for my home shop.
Ally helped out tremendously and always quickly emailed me back the answers to every one of my questions. I will surely be using American Rotary for any more of my future rotary phase converter purchases.
A+++
Just wanted to say thank you to Ally and the team at American Rotary. Such great customer service and such an easy process to get me up and running. It’s been so much easier then dealing with a VFD that I received with previous lathe….I knew I wanted an easier path with my new to me Bridgeport Mill. Ally walked me through pros and cons of certain models and how to best suit my needs.
When funds allow (just being a home hobbyist) I will replace my VFD with another American Rotary Phase Converter. Cant wait to see how shop grows and how our relationship will grow! Thanks all! Our new daughter Elizabeth love to be present in garage while doing non-machining work!
American Rotary makes it so easy to wire these things in, any monkey can do it, and I am the living proof.
Second American Rotary Phase Converter installed yesterday, the first served my company well for 13 years and was still operational, I had just heard the signs of bearing wear and decided I should replace it during our slow season instead of waiting for its demise risking down time during busy season.
Jacob Pawley was so helpful in determining the size and making the process smooth, even checking in after the delivery to see if I had any questions and offering support to my installer. Quality and service second to none!
The entire process was as easy as could be from sizing of the converter to sales advice and shipping it couldn’t have gone smoother.
Once the proper single phase power was installed the process of connecting the ADX-20 went really smooth. The enclosed instructions perfectly outlined the steps and in less than 30 minutes we were up and running.
This unit runs so quietly we only know it’s running because our CNC is operating, you don’t even hear it over ambient noise of the small shop.
Thanks for making a quality product that I am sure will last for years to come.
I recently acquired a Prototrak DPMSX5 Bed Mill and Prototrak TRL1440 Lathe and needed to install a Rotary Phase Converter.
After many internet searches and reading a lot of reviews I settled on the AD10 from American Rotary. I am so impressed with this company. Ally from American Rotary answered all of my questions and was so pleasant and so professional.
I have attached a photo of my installation. The bottom right side of the converter is my 220VAC single phase input (with disconnect), the top runs to the attic where my 10HP 3-Phase idler is installed, and the bottom left runs across the room to my 3-phase load center.
Got the ADX-10 up and running. Powers my Air compressor, Bridgeport, surface grinder, and manual lathes. Great product.
After being retired from a Rolls Royce restoration shop that my Dad started in the mid-sixties,it was time to get my Bridgeport wired and working.The American Rotary AR5 was my choice to get the 3 phase 220 power it needed.
Ally at AR was able to answer my questions and took my order. My order was delivered on time,in good condition. The installation instructions with a guide to wiring, made the unit a breeze to install and get running. Well I’d no longer work on Rolls or Bentleys I do however restore Stanley Steam Cars.
Installation was a breeze and the unit works as advertised
I had several dealings with other supposed manufacturers of Phase converters before finding American Rotary. All were very bad experiences and made me doubt the whole industry.
I finally found American Rotary and I can tell you there will be no other name at no other cost in future considerations for this product.
I am more than thrilled with my AI50 unit as well as everyone who comes and can see it running in my warehouse. Pure quality and pure support in setting it up.
My Electrician will now only suggest American Rotary.
I have a skid of past experiences of trying to find a company and this solution. Do yourself a favor and stop at this page and be thrilled and save yourself the grief and cash that it cost us till we found them.
I wasted a lot of time and money on cheaper static phase converters trying to run my woodworking stroke sander. Both made it work, but it sounded like a freight train and I knew I was tearing my 3-phase motor apart.
Then I found American Rotary. WOW, that’s what my sander is supposed to sound like. Full power, fast start-up, super quiet. It did exactly what you promised.
Now I’m off and running with my backlog of wood projects.
This is a picture of AR10 installation in my mobile machine shop to add to my earlier testimonial.
I purchased an AR10 phase converter to power a 1907 South Bend 16′ Turret lathe. This machine is in a mobile machine shop that I built in a 16′ enclosed trailer.I will soon be ready to start a business.
It was great to find knowledgeable sales staff that could quickly and accurately answer ALL of my questions on the first attempt! Ally was great to work with. Our phase inverter is working great!
I have two ADX series phase converters and both work great for my metalworking equipment. When I had trouble with a wire remote switch, I called American Rotary and Jacob walked me through it step by step.
Everything worked just like described.If you’re in the market for a phase converter, I highly recommend American Rotary. Not only for the high quality products, but the amazing customer support you’ll receive as well.
So far so good. I had a unit that had been pieced together, was a pain to start, and noisy when it was running. I replaced it with the 5HP unit and could not be happier. I mounted the control box, wired it all in, and turned it on.
I actually had to turn a fan off to hear the unit running because it was so quiet. I have only used it for about 45 minutes total run time but the ease of starting and quietness of operation are very much appreciated.
Got the AR7-UL 7.5 HP installed and it’s working like a charm. Easy to install and wire. I have another American Rotary 3 HP converter I bought over 5 years ago that’s run without the first problem, and I fully expect this one to perform just as well.
Both units are running metalworking and woodworking machines flawlessly. These are top notch and I’d recommend them to anyone.
Not too many companies follow up before and after the purchase to make sure everything’s working. Rest assured, if I need more equipment in the future, it will be American Rotary.”
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.
Installation of AD10 American Rotary Phase Converter and motor is complete, photo attached. Could not have been any more straightforward – I am not an electrician by any means, but was able to complete all of the wiring with no issues, and just had a licensed electrician in to validate my work and make the connection my home service panel.
The motor is exceptionally quiet, the overall product quality is top notch, and the customer service received in talking through my needs was impeccable. A couple of techs spent quite a bit of time talking me through the details, giving guidance on wire gauges, and tips on initial set up. Excellent service.
