    Default Wanted: Motor Starter for my lathe

    I am looking for a motor starter with reversing feature for a 5 hp single phase 220 vac electric motor. Does anyone have a used one laying around that they want to sell? Based upon what I can understand in the Granger catalog, it would have to be a 30 amp. I am replacing a 3 hp 3 phase motor and it appears that the old starter-contactor-relay will be too small. I would appreciate any suggestions as well. The only other option I can think of is to put two disconnect boxes on the front of my lathe. Uch! Thanks, unclelonnie

    Reversing a single phase is not as straight forward as you think and I really don't like doing that. If you have the motor up and running and flip things from forward to reverse, the motor keeps going forward. You have to wait for the centrifugal swith to engage before changing directions.

    Are you sure you really want to go to a single phase motor instead of going with a VFD or a RPC?
