I am just wondering who out there has a Hardcore grinder and/or the Baldor motor that comes with it?

Are you running it on 110V or 220V? How does it run? How long have you had it? Any major repairs? Do you find not being able to adjust it a drawback? Anything that strikes you as particularly good or bad about the motor?

I am trying to decide on a VS motor and really do appreciate your feedback.

Thanks,

John
 
I have a Hard Core grinder with the 1 1/2 horsepower VS motor. I have had it since 1999 or 2000. You are not able to run this motor on 220V, it must be ran on 115. It is OK but just doesn't compare to the Wilton 6X48 upright grinder I have as compared to power. It has a 1 1/2 motor wired for 220 (fixed speed motor) and I can't slow that belt down no matter what.

In my opinion the Baldor VS motor setup is a smoother setup than the ones I have used on a Bader grinder. The diference in the grinders don't have anything to do with it. The speed control on the Baldor is top notch.

had mine for 2 1/2 years runs fine and smooth. i had the motor go out at under a year. it was replace with a new one from john mallet of tru-grit. there have been zero problems since. i grind six days a week some times and the smoothness of the grinder helps cut down on fatique from vibartion. the secret of not bogging down really any set up is sharp belts (good ones) and developing a touch for the right amout of pressure. so the belt is fracturing the steel off, noy gouging it off.
 
Are both of you running 110V? I ordered 220V and understand that running 1.5 HP VS motors on 110 may be a large part of the problem (as opposed to any internal problem with the motor itself.)

they may have a bit more power at 220v but i have not heard that running them 110v has a bad effect on the motor?
 
I work mostly with 3 phase motors but in my mind a motor that has the windings for 220 amd you run 110 through it the motor is going to need to draw more amps to get the work done. The motor is going to run hotter and less efficient than it should. The motor wont blow but you are shortening the life of it. Not to mention the waste of electricity. I'm sure there is somebody who can explain it better than me. When I get my shop set up I getting 3 phase if possible, its so much easier.
 
The 1 1/2 horsepower VS Baldor motor/controller installed on the Hardcore grinder cannot be wired for 220VAC.

I thought you could run all of those DC/Controller motors on 220V. I have four and all of them are switchable inside the controller box to either 110 or 220V. I have never seen one that isnt. Are you sure about that?? If it is so then you just need to get a different box, cause the motors are all the same.

That's interesting. If you can post the model number of the drive and motor I'll look it up. Been selling and servicing Baldor motors and drives for quite a few years and thats a new one on me, but it is possible. I'm running a 11/2 hp vs on my grinder and it seems to have good power. mw
 
The "spec no" on the motor equipment plate is 35P575Z26061. I cannot find it on the Baldor website. RPM is 2500, armature voltage is 90 volts. A model number is not listed. I have no idea what the controller would be. It is built into the base.

When I asked the question quite a while back the reply I got back from Tru Grit was that it couldn't be wired for 220VAC. I pursued it no further. I assume that it may be due to the motor/controller package.

If you come up with a way, it would be much appreciated if you shared the information.

c. Wilkin; News; the baldor unit is a motor and control built together as a unit special for Tru-Grit. The unit is 120 volt only. An odd duck. But the power should be pretty good even on 120 volts, cause watts equal power. If the controller is going on you it would be easy to put a add on controller on it that is switchable for 120/240 volts. If the motor is bad I would replace it with a standard frame motor and shim the base to match. Better, stronger, cheaper. You might downsize the drive pulley,from the one you have on it now, that always gives you more realized torque on the belt. hope this helps mike
 
For the record, the folks at Baldor tell me the 1 1/2 hp I have is variable torque as well as variable speed, less speed, less torque. CL, that number matches mine. If you call Baldor in Ft. Smith and ask for their grinder department manager (I keep forgetting his name, sorry) he'll be able to tell you more about this motor. He was the one "shining star" in helping me get mine repaired up here in the Northwest (see other thread on being picky).
 
Folks,
I haven't had the first problem with the Baldor motor or controller that is on my Hardcore grinder. I was just stating that it couldn't be wired for 220VAC. I am satisfied with it but would like just a little more "umph". On the other hand, if I had a 5 horsepower motor, I would want at least 6 or 7. :)
