10" Sioux bench grinder

[scrapdaddy]

Hello Everyone,

I just added the 10" Sioux grinder to my collection. It's a 1 HP motor that can run on 220 or 110. I have three other Sioux grinders, but smaller Hp., that run on 110. What are the advantages and negatives to run this one on 220?

Thanks,

Ron

Less wear and tear to the motor (less heat generated)(and I think we're splitting hairs at this point)...even though a good Sioux would last forever on 110 when cared for.

I'm curious to see what the experts have to say....

BTW, I just redid my Duralast 10" 2hp 110/220v 18.5amp this weekend. I'm running it on 110...just b/c I move it around.

If both circuits are properly set up (sized) for the application there will be no running difference in the grinder. The problems start to arise and differences become noticeable when someone changes a 110v saw on a 15amp breaker in a 50' extension cord, to a more equipped (read proper) , 8' run 220v outlet.

If you have a spare 220 outlet just sitting wide open in the exact spot you want to put the grinder then run 220. If you have to do any wiring at all, it is not worth the work and run it 110.

So, you guys are saying it wouldn't run any better on 220, more rpms, won't bog down, etc. I've got 220 in the shop, but would have to special wire to a spot for the grinder. No reason for it, if not worth the trouble.

Any of you guys collect the Sioux grinders. I've got four different models, so far.

Thanks for the responses.

It will run better on 220VAC!! Since less current is required, the resistive power loss that occurs in the motor and the circuit will be less. (simple ohms law: P=I squared X R). Less power loss = less voltage drop.

The difference is not usually dramatic, but given a choice always opt for the higher voltage option.

For a 1hp motor it won't make enough difference to matter either way. However, it will need a 20 amp circuit, so if you only have 15 amp 120vac circuits in your garage you'll want to go with a 240vac connection.

Thanks guys, good information. I have 20 amp circuit breakers in the shop and 50 amp & 30 amp for the welders and air compressor. So, leave it at 110.

Here's some pictures. Not sure how I started collecting them, but have four so far.

I'd be so jealous if I didn't already have more grinders then I need.
