New field for a Baldor 500 Tool Grinder

[Andybull]

I purchased a 1hp Baldor Grinder, along with a Model 500 Tool Grinder at auction a while back. After setting them up (they came installed on a back to back heavy duty base), I tried them out. It turns out that the tool grinder's field is fried, I don't know if the armature is also.
Is there a company that will rewind the fields? Baldor lists the part but not the price, if I can find a company that will discount the components, I'll just buy them new.

The grinder in question is behind the grinder in the foreground.

First of all, it's fairly uncommon for a stator winding to burn out. Most motor problems turn out to be something else like the starter circuit. (caps, centrifical switch, bearings, bad wiring connections, etc). Have you checked the run and start windings with an ohm meter?

(ie) measure run to common, start to common, run to start and then run and start to the iron frame of the stator.

Secondly, the rotor of one of these split phase induction motors has no windings to burn out. The entire rotor is laminated metal pole pieces. (ie no wire)

If it really is the stator, then you just need to search the phone book for a motor repair shop. If you find a shop then you'll probably find that the cost is too high or the shop will refuse to work on these small motors. (motor repair has become very specialized with focus on larger industrial motors)

The field's fried. I am sure it was either wiring, or maybe the capacitor. This grinder sells for over $1,200.00, so I would like to repair it.

Now you know why you were high bidder.

As Dave said, there are no more small motor rebuilders in most areas. The two here stopped doing anything other than large industrial stuff twenty years ago.

Any time I've tried to buy new major parts such as field/stator/housing for a small motor, it was less expensive to find another used but working machine.

Your results may vary, so let us know how it goes.

Don't know how close they are to you, but http://www.electricmotorandrepair.com/ should be able to do the job. By the way, nice looking shop you got there.

Andy? What ever became of your inoperative motor?

I kind of gave up on it, because the athorized factory dealer wanted to charge almost as much for the field as a new grinder.
I had not subscribed to this tread and just noticed the posting above yours, showing a place in Columbia, SC.

I have the exact same grinder with the exact same problem. Did the place suggested above able to help at a reasonable rate?

I e-mailed the company, they never replied.
