So i picked up this realy nice baldor motor! 3/4 hp single phase, figured it is definelty worth the $17.50 i bid on it! It ran great, incredibly it came with a free drill press!

I really wanted just the motor incase i need to swap out a 3 phase at some point. But having a drill press will be decent, it is a champion brand. However the whole thing wobbles when the motor is running.

Where is it wobbling? The arbor or the motor itself?

Remove belt.

Run drill press motor. If it still vibrates, remove pulley from motor, run motor by it self.

If motor does not vibrate w/o pulley, get new pulley.

If motor does not vibrate with pulley, get new belt (think about a link belt, might be worth the cost).

If unit vibrates when new belt is installed, check quill pulley and bearings.

Good Luck!

Be Careful!

I will be uploading a video of it running. Its not a bad wobble, or vibration, just a slight one from the motion. You cant even tell from the video.

I have that exact same motor on my ancient drillpress! And it is a beast.

HerbC’s advise for diagnosis and treatment is spot on!

Edit: watched the vid and vibration didn’t seem bad from here. Maybe a bag of sand or other weight on the base. Also shims under the base if the floor isn’t perfectly level.
