  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.

  American Rotary has been a wonderful company to do business with and as their name states they are an American company! I am in the process of getting back into machining again but this time in my own shop. I had purchased some machine shop equipment that required 3-phase electrical power which I did not have living out in the country. I had tried an inexpensive digital converter that made my machine motors very hot due to unbalanced power in each of the three output electrical phases. A person I had purchased a milling machine from said that he had an American Rotary 3-phase converter and was very happy with the quality so, I thought I would give them a try. They were very helpful with steering me to the converter that would meet my needs. When I received the unit I noticed the control box had a dent due to the shipping company being too rough with it. I called American Rotary and they sent me another control box immediately. The unit works flawlessly and is very quiet plus my equipment motors do not even get warm. It has been very nice to deal with an honest company that looks out for the best interest of their customers.

  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. When working with one of the salesmen, Mike, I was informed that my machine would have to be built to order before shipping. Now in most cases, I've found that "built to order" means a lead time of several weeks at least. In this case, I was told that due to the unit needing to be built to order, it likely wouldn't ship until "tomorrow afternoon" - and that's exactly when it shipped. Incredible! After receiving the shipment and unpacking it, I was impressed with both the build quality of the converter and with the crating/packaging of it! This is the epitome of American manufacturing - quality products and amazing service. I've gotten the converter up and running some of my old machine tools and it is absolutely outstanding!! I would recommend American Rotary to absolutely anyone looking for 3 phase power where it's not available. The team makes selecting the right unit and options a breeze and turnaround time is quick. 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 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 what so ever. The unit is quiet and works flawlessly. Go with a USA American Rotary if you need 3phase power.

  As it was snowing this Sunday, for the first time in four years here in Georgia, I used the opportunity to install my new American Rotary AR 10 Phase converter. As advertised, it was professionally packaged and everything needed to install the Idler, converter panel and 3 phase load center was included. The directions were simple, clear and in several locations so it was easy to double check myself as I worked. When I was researching which converter to purchase, I spoke with two other companies about their product. In both cases, there wasn’t much information as to what I would need in my particular situation. I was offered a price for the converter only without much help as to choosing the correct one. When I spoke to Ally at American Rotary, she asked lots of questions concerning not only my equipment but of my shop as well. And when she sent the quote it included everything I would need to do a complete install. From speaking with Ally and from reading the information sent with the phase converter, I knew I needed to change my breaker and wiring that was running the VFD’s I used to power my 3 phase equipment. Once this was done the install went easily. I followed the instructions fully and the unit came up on the first try. I have a hobby/repair shop at my home. I have been running several pieces of 3 phase equipment and recently added a larger lathe. This is when I started having more problems with how I was powering this equipment. You only realize about two thirds the actual horsepower of the motor you are running. This was causing problems with my vertical mill and the larger lathe. Now that I have the AR 10, not only is my equipment running stronger, I can run two machines simultaneously. I am so pleased with my AR 10 and with the service I received at American Rotary.

  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 Phnix 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.

  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.

  I am EXTREMELY satisfied with American Rotary! I was hesitant to spend the extra money over the other phase converters that I was looking at, but often times you pay for what you get. This is most definitely the case with them. Their idler motors are so incredibly quiet that you can't even hear them run while your machine(my mill or lathe) is running. The installation is very straightforward. I purchased the 3 phase load center with the ADX10 to be able to use multiple machines off the same converter, which is definitely the way to go. Furthermore, the customer support is second to none(the best I have had in a long time). I wasn't exactly sure the breakers that I needed and questioned the way to wire the load center, but their quick email and call responses quickly answered my questions. I received an email shortly after I received the parts asking if I had any questions about installation, needed any help, etc. I AM A VERY HAPPY CUSTOMER and will recommend them whenever possible! Remember, you pay for what you get! Check out the pictures/videos of this on my Facebook/ Instagram Kuehl Enterprises.

  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! Hope you enjoy!

  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.

  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

  When we were looking to purchase a rotary phase converter for our shop we noticed a lot of price differences. Having bought cheaper items in the past, we knew all too well of quality and support issues down the road. Therefore we choose to purchase from American Rotary. American quality and American support. We are in our seven year of usage without a problem until we recently relocated the system to accommodate some new machinery. Due to our error, the converter wasn't working properly. A quick call to Chris at American Rotary and within a couple minutes, he directed us which lead to the discovery of our installation mistake. Within minutes, the entire system was up and running. No service calls, no fee's, just great help. A+ company.
