Thread: Most affordable electric motor supplier?

I've been making knives and a few razors off my 4x36belt/6" disc combo sander and have had a no weld grinder justsitting...the electric motor that I had purchased new ended up being nogood. I am in search of a 3 phase, 2hp motor with 7/8" shaft (I alreadyhave the drive wheel) with a 56c mount. I would prefer a 1725 rpm motor,but 3450 would be ok as I will be running it thru my vfd drive.

I have the OK from the wife to buy another and would liketo ask you guys who you use that is most affordable. I would prefer aDayton or other well known motor that can be rebuilt if at all possible.

am building a phase convertor for an oliver saw,just snagged a 4 HP Baldor off C.L for 60 bux.
You can also have electric motors re-built cheap.

C.L.? Where/who is that?

Supposedly this motor can't be rebuilt, don't understand that one.

craigslist,any electric motor can be rebuilt,are pretty simple things unless it is totally burned up.
I just re-built my golf cart motor because I will not pay 400 bux for a new one,turn the armiture on the lathe,two new brushes,two bearings, 21 bux out the door.
My question to you is,why in the hell do you need a three phase motor on a grinder?

That's the part that I didn't understand, I thought any motor could be rebuilt. I bought it literally brand new from a motor shop in a Durant, OK near the railroad tracks. I stopped the train and went over there, he had just bought out a electric motor shop and had that one on the shelf & I bought it. Two years later, I get the rest of the stuff for completion of the grinder in a box like Brad/Undream built years ago. I want three phase for the vfd & I want vfd (variable frequency drive) for infinite speed control. So far, this is the best price I can find, but need to find out how much on the shipping as it can range from a fair $30-40 to outrageous: (VM3558) 2 Hp, 230/460 Vac, 3 Phase, 56C Frame, C-Face, 1800 Rpm - Baldordirect, your home for Baldor Motors & Drives

Is it an offshore made motor?? if so,cannot get parts for them,any brand name american made motor can be re-built,have done no less than 5 in the past 30 yrs.

Because variable speed using a frequency convertor is a lot easier using 3 phases. 3 phase is industry standard.
My grinder has a 3 phase drive. The frequency convertor is 1 phase, but outputs 3 phases specifically for this purpose. Having 3 phase motor also allows for controling the direction via the frequency convertor.

If you have time, look around for estate auctions at farms.
Around here you can get a used three phase motor for about $5.
