36 slots. Does that give anyone any ideas?
The motor is back together now, and I think I'm going to proceed with the rest of the project (making an interface for this motor to drive a metal lathe) for now. When I get everything ready to use, I'm planning to wear ear plugs. We'll see if that...
$100 for a growler test. That's not so low that I definitely want to do it, but it's not so high that it's absolutely out of the question. He said it would be definitive; if it passed the growler test, it's a good rotor, otherwise something's wrong. I forgot to ask the guy, "What then?" If it...
I measured actual speed and it was right at 900, so even closer than the nameplate states.
A friend suggested either a loose, wiggly wire in the stator or a loose lamination in the rotor, then pointed me to Glyptal products. Another suggested looking into having the stator vacuum dipped. I'm...
Thanks for your input, waross. I suspect the 220 volt label has to do with the manufacture date of this motor and the changes to electrical standards and nomenclature over time. I realize the RPM is unusual, which is what makes this motor so useful to me and makes it difficult to affordably...
This motor has a terrible, high-pitched whine when energized, and I'm trying to figure out the cause and eliminate it, if possible.
Manufactured by Diehl
Rewound for only 220v previous to my acquisition
Nameplate info (220v): 2 HP, SF 1.15, RPM 860, FLA 7.8, 3 phase
It will be driven by a VFD...
