Hey, and merry new year!
I recently, at a flea market, bought a small really hq looking drill press, and I got it for very cheap because the motor didn't work, since it 'blew the fuses'.
It's a 3-phase motor, and I assumed it was used as one-phase, and there was no start/run capacitors on it, so I suspect that's what's tripping the breaker rather than an actual winding short. I don't have much experience with mains voltage motor stuff, but I'd like to get it running, before considering getting a 1 phase replacement motor.
Here's what I can see:
- three phased
- one side of each of three coils shorted into star config
- no start/run capacitors added
The coils all measure the same resistance, so I guess there aren't any direct shorts. I don't have a megger, so I can't check the insulation..
Now, there's a lot of diagrams out there for motor wiring, but I still seem to find some conflicting info.
What would be needed to get this running on a single phase?
I know it'd be running at less power, but the chuck only takes like, 4mm drills, and I mainly work in soft metals and plastics, so that's not an issue.
It's not a big motor, a tad larger than a can of soda, but it seems to be very high quality, made in Germany, and looks almost new.
Thanks in advance,
