Update - the righthand unit is sold. The left one is still available.
Hi,
I have two Variac type variable transformers. These are used to reduce power to electrical motors/tools in order to run them at partial power or rpm. They will with motors that have brushes. If your motor does not have brushes I do not believe that this will work for you. These are used but fully functioning on 110v single phase current. They are $50 each.
Please drop me a note if you would like to take a look.
