Steven Bronstein Posted May 17, 2022 Share Posted May 17, 2022 I have access to a Kuhn KB1 hammer. It is set up with a 3 phase motor. I want to swap out the motor for a single phase one. What other problems should I anticipate? I understand I may need need a new Mag Starter. Anything else for me to worry about? Thanks. Also, are parts still available for the KB1 Link to comment Share on other sites More sharing options...
jason0012 Posted May 19, 2022 Share Posted May 19, 2022 A three phase starter will work with a single phase motor. You just leave one leg open. Link to comment Share on other sites More sharing options...
WestCoastHunter Posted June 15, 2022 Share Posted June 15, 2022 They make VFDs that are single phase input and 3 phase output, you can buy them on ebay for 100 bucks, i use one on my drill press and belt grinder. Link to comment Share on other sites More sharing options...
Broad River Forge Posted August 29, 2022 Share Posted August 29, 2022 ive done it twice on the Kuhn clones, (Sahinler) once was a 60KG i swapped out to single phase 7,5hp motor no issues and just a couple months back a 50KG sahinler with a 5hp single phase motor. no problems. its pretty straightforward before she was powered up but its simple, just getting a pulley right size or adapting it to the new motor takes some figuring Link to comment Share on other sites More sharing options...
