Sac & Story county IA | A rotary phase converter is basically an induction motor operating on single phase power that acts as a rotary transformer and produces power on the third winding that can be used to operate a load motor. The phase converter output is tuned with oil filled capacitors to achieve the best voltage balance.
I have built and used them for more than 20 years. The problems are about the same as with any other motor setups. Mice getting in and eating insulation, water getting in a motor, bearing drying out, contactor points getting dirty and corroded, ad infinitum.
The other benefit from a phase converter is the ability to use 5, 7 1/2, 10 hp motors on loadout motors. Used motors are usually really cheap on the scrounger market. Plenty of contactors on ebay.
I do think vfd's are wonderful. I use several. But the workhorse of a grain drying and handling facility is a large idler motor making 3 phase power. | |

tell me about three phase converters
