Hi all,
I picked up a very nice baldor motor (IDNM3587T) from my local scrapyard yesterday, and have a few questions about it. It's a 3phase, 2hp baldor industrial motor. I've attached a pic of the tag.
1) It looks to be in good condition, and the spindle spins freely and coasts to a stop. I was planning to wire it up to my VFD to check if it runs. Can I damage the VFD if something is goosed in the motor, or is there anything else I need to check before powering up? It's currently wired for 440v, but I'll be rewiring it for 230v.
2) The main arbor shaft is 7/8", but on the back of the motor there is a smaller 5/8" arbor sticking out. What's the purpose of that? It looks too short to be for a buffer/grinder, and that wouldn't make much sense given this motor's intended application..
3) The tag says the motor is 1740rpm/ max 6000rpm. Does that mean that the motor can be run at higher frequency (using a suitable VFD) for those high speeds? What's the downside of doing that, if any?
4) What does the "TE" stand for after the horsepower rating?
Thanks in advance for your advice,
Lee
