Need 3 Phase power but only have Single Phase use a Converter

Rotary Converter

You have been to the auction and you got this great deal on a commercial  mixer  for your pizza restaurant and have your electrician friend come by to hook it up but there's a very big problem .
The mixer is designed for 3 Phase electrical power and you only have Single Phase in the restaurant. Now what
 well you have a couple choices. Put in a 3 phase service if you can get it from local utility  for couple thousand dollars.  Change the motor if  its even possible which can run a thousand dollars or more , or you can purchase a Phase converter from a company like Phase- a -Matic

There are 3 basic types of converters available on the market  depending on the type of load required to be operated. Digital, Rotary and Static . Static converters where available as a kit form and you added capacitors to meet the load  ,however they where not UL listed I installed several of them and inspectors frowned on them but properly installed they worked fine  or you could take an old 3 phase  motor and build a rotary converter as well . These units where not very efficient but they got the job done I saw entire machine shops run off rotary converters built by electricians.  Finally about 25 years ago the first UL listed static converters started coming on the market and where  recognized in the NEC code along with there rotary cousins

Now you see them common place instead of  hand built which is a much safer way to go.  still not cheap its still cheaper than having to have a service put in or changing a bunch of motors and controls. With digital technology you can easily  control motors with them as well. A customer of mine recently got in a specialized piece of  portable dehydration equipment which  allowed a 2- 1/2 HP 230 volt  3 phase motor to run off  simple 120 volt outlet unheard of just a few years ago digital phase converters are allowing all kinds of equipment to be operated easily in the field which was never able to be done before with out dragging a big generator with you.  need 3 phase and have just single phase convert it .
