Dont have three phase power in your shop?  Not a problem.  There are three options:

1.  Talk to your electrical supplier to have them quote on running 3 phase power to your shop.  In our shop, the cost was going to be over $40,000 so that was not a good option.

2.  Install VFD's on the various 3 phase machines that are in your shop.  We have used VFD's in our shop but in discussions with WEG engineers, they recommended rotary phase converters as a better option.  Their main concern was they typical dust and heat in a blacksmith or knife making shop.  WEG only makes VFD's.  They do not manufacture rotary phase converters.  

3.  Install a rotary phase converter.  That was what I did in my shop over 12 years ago.  A rotary phase converter should be considered an overall shop upgrade.  If you size it properly, you can run multiple three phase motors at the same time.  You can wire your shop with multiple 3 phase outlets just like you would do if the power company supplied 3 phase equipment.  


Sizing the rotary converter is critical.  Not all rotary converters are the same.  Typically, for a "hard start" application like an "air compressor" (or power hammer), rotary phase converter manufacturers recommend a converter that is 3 times the single phase motor you will be starting.  In other words, if you have a 10 hp 3 phase motor, they would recommend a 30 hp rotary converter.  


ADX rotary converters have unique electronics that provide extra capacity for the instant startup loads.  We know that the ADX20 has enough power to start the 10 hp 3 phase WEG motor on the 130 and 168 lb. power hammers and also the 10.4 hp motor on the 50T press.  


I am not an electrician so I will not recommend a specific size for your application.  I will refer you to the America Rotary website or their technical support group.  I do recommend that if you are ever planning on running more 3 phase equipment in the future, that you include that in your sizing decision.  Here is a link to the American Rotary website:www.americanrotary.com  Their phone number is: 1-888-7436832
