Is this a good motor for a grinder? I downloaded the manual but it does not say whether it is TEFC or not. The part number is 41376-0CGH.
 
I have one on my Coote and it works fine for me. I set it up using 220 with step pulleys I've only been able to bog it down at the highest speed if I'm really trying to hog somthing which isn't a big problem for me. Oh and by the way it's a TEFC.
 
I always keep an eye out here and there, surplus places, (sometimes on ebay) for nice Baldor motors. I usually stay away from 1 hp, opting for 2 and above. That is about the price range I will spend for one of these motors in single phase. If you're a little patient you should be able to score a nice top-quality American-made motor for that sum, which is what I'd do, but that's just my preference. I tend to sweat the details when building or setting up my equipment.

(For a grinder, 2 hp three phase with VFD is the way to go -- you'll never look back.)
 
I have that precise HF motor in me bandsaw. Swapped out the stock "3/4 HP - Sears rated" crap - the thing wuz so bad, it woudn't even spin up to the full speed, with blade installed !

The motor is top notch, I wired it for 220.

Buying motors on Ebay, you need to go for a new one I guess, ez to get one with bearings shut, and they all weight a lot, so you pay for shipping too.
 
I would love to have a VFD, but so far they are out of my price range. I have been looking on ebay, but haven't seen one I can afford.
 
I've bought several motors on ebay and they were all perfect. You can often tell how old/used a motor is just by looking at it. Buy them as new as you can (which is often very close to brand new). If it looks old (old style, greasy and scratched up, pass) Always buy from someone with lots of good feedback. Never buy from questionable sources, ebay or otherwise.

About 10 years ago, I had some Chinese motors. Some were good. Some insultingly bad. I know their quality is better these days, but personally, I'd rather have a good, used Baldor than a new Chinese motor.

When searching for VFDs, be sure to search under " VFD, Variable Frequency Drive, Motor drive, Variable Speed Drive" and any other title that might fit. There are several search terms that I usually use, but I can't think of them all right now. The key is to find the right drive listed somewhat obscurely so that not too many people ever see it. Then you can pounce.
