Hi everyone. I fried the motor on my 10" saw. IThe blade bound up and I was on the other side of the house. I smelled burning wiring, when I got to the saw the blade was frozen and white smoke was pouring out of the motor (there were some small flames inside too).
My question is, can I replace it with a 3450 rpm motor? The saw is a stardiamond/barranca 10". I don't have any room to put a larger pulley on the arbor and I assume a larger one on the motor will just speed things up. I have the correct replacement motor but it's a 6 hour round trip to go get it.
Can I make the motor I have now work or do I need another 1750 rpm one?
Thanks, Geoff

if you change rpms you will have to change pullys or you will burn up blades in half the time you will heatup the diamonds more and they will just come off instead of wearing out-- you can go up in horse power i did that and it had no effect on my blade the saw just ran smoother never binding -- i went to 3/4 from a 1/2 horse and it never ran better
im convinced they sell saws with the min horse power they can run with both my lortones where under powered i went up with both and they ran so much better--- no more binding on small hard stones that should have been no problem

Geoff, Looks like you are in for a trip unless you can find a motor closer to you. You really don't want to replace the burned out motor with one rated at 3450 rpm, you will have doubled your blade speed and that is no good for the blade. Probably will burn it up post haste. When you get a replacement try for one with "thermal protection", if this sort of situation ever happens with it the motor protection circuit will function and cut the power off inside the motor saving it from burning up. Check the motor data plate. Good luck Jim

you could run a lower quality construction blade for a short time. They are rated for faster speed, and if the life is shorter, well did I mention low-cost constuction blade?

jims right about the protection circuit i have a button on mine if it binds up it will pop the circut and stop the motor mine has never poped since i got the new motor but who knows when a rock will move in the vice and bind it happens to us all and the bigger the saw the bigger the price on the blades when they get bent haha
fishman have it shipped to ya hell prob half the cost of the gas you will use not counting the time

Thanks your help guys. I won't use the higher speed motor, I'll have to take a drive. It's at my place in the Lost Sierra near lake Oroville, nobody there to ship it. At least I can do some brown trout fishing, now is the best time of the year ;D

I forgot about my wet belt sander. I took the motor off of that but I guess the wires were loose (always worked before). My question is, where does the ground wire go? I assume it goes to the body, maybe on the access cover screw? The black and ground came loose. I figured the black belongs on the post oppsite the white wire. Pic:

Mr Fishenman: You are correct about wiring the green wire to the cover plate. A quick suggestion about marking wires and which post. I take a magic marker and put A "B" over the black wire connection and a "W" over the white connection. Helps me keep things straight most of the time. Hope this helps!

Thank you Frank. One oops, the shaft is larger than any of my pulleys except for a 3" and I need a 1.5"(Do'h). Great tip on labeling the wires! Geoff

Notice how the connector posts are 2 different colors? The copper colored one is (usually) for the black lead and the silver colored one is (usually) the white lead. They will be different if someone has changed stuff around inside the motor or if someone has the wiring backwards in the house, I have seen both.

Yes, I do remember that now. Thanks Tony!

The green screwis technically the ground but the cover screw will work also. If the motor clamps into a cradle (resilient mount) there may be a ground from there to the cradle also.
