I’m looking to purchase an older powermatic 50 jointer that has a 3 phase motor. I do run 220v in my home workshop for my table saw but do I need to purchase a different motor for the jointer or can I use it as a 3ph?

You can use it as is. What is the FLA of the motor? Figure on $200 or less for a VFD. Less costly than a motor swap and lots of extra benefits (besides the fact that a three phase motor is more robust and more efficient).

if you go the route of using a VFD and the 3 phase motor, don’t hard wire the jointer to the VFD. Set up the VFD with a 3 phase female plug and a male plug from the jointer. If you happen to get another piece of equipment with a 3 phase motor, all you would need is to get another 3 phase male plug….......... Jerry (in Tucson)
