I recognize that I'm at risk of posting this in the wrong location, but to be frank posting questions in 'General' slightly terrifies me.
Here goes:
I have a dust collector with a 3hp 1ph motor manufactured by Leeson, it began making an odd noise while running, sort of like a surging. On advice I replaced the capacitors, I did so with identical units to ones being replaced. Problem resolved.
A month later now the problem has returned, replaced the capacitors but that magic pill approach has failed me, and the motor continues to make the same noise.
The motor seems to function but I can't quite understand what is causing it to produce such an odd sound.
- I've checked the simple things, all is well in the electrical panel and at every connection between that and the motor. I have checked the connections at the motor. It does not sound like a bearing noise to my ear and I dont believe anything to be rubbing or stuck in the impeller.
Help would be appreciated, I'm attempting to avoid simply being a feckless parts changer and actually diagnose this to find the problem rather than chuck it in the trash and install a new one.
Rather than try to mimic the noise I've taken a video which I have posted on youtube.
