Quick 110/220 question

[Twiztid_66c10]

I have a older compressor I have been using right now it's running off 110 but was cleaning it up and it says can be wired to run 220. I do have 220 in my shop and wire to do it what's the benifits in 220 vs the 110 and where could I find wiring diagrams becouse this is a away older motor and huge lol

most motors have the diagrams on the motor it self

the wiring diagram could be on the inside of wiring termination cover the advantages that you can at a lower amperage over 120 volts but would need a double pole breaker over the single pole breaker with 120 volt

It won't save any electric changing it to 220. If it is already wired and working 110 no need to mess with it. Electric meters are billed using watts not amps. Only advantage 220 has is smaller wire for less initial costs.

Not really worried on cost shop is already wired 220 and have all plugs to do it just heard its easier on motor with 220 wasn't really for sure. This is a older motor/ home built compressor setup so didn't see a diagram on it so will have to look it over again

It will generate less heat in the motor at 220v

And run way better.

I figured there was no point in starting a new thread for a simple electric motor question.
I have this heavy duty motor that has this plate on it. I'm pretty positive it's 220v.
But why does it have 115v in addition to 208v-230v ?
I just can't see this big of a motor being able to run on 110.

Yes that is a little odd for a 3hp motor to have the option of running on 115/120V, but that motor does. If you look at the full load amps, you will see that you will need a 30 amp+ breaker to run that motor. It will be much more effecient to run it on 220/230V.

Thank you.
I have another question.
I think it's been 10 years since we used it.
One time I let a friend borrow it and it looks like they put on a different plug.
When I took it apart to see if I could figure out what went where so I could plug it in to my dryer outlet, I noticed there were two black wires that he must of cut to wire on some different plug.
I don't know now what goes to what as far as hooking it up for 220v.
Here is the dryer cord that fits my dryer outlet;

.
And here is a picture of the cord on the shot blaster.; There is a brown wire, a greenish blue wire, and a green&yellow striped wire.
The two black ones he cut and had going to nothing.


I guess I just need to know which color wire goes to which prong on my dryer plug.

[LostMy65]

I think I'm getting closer to figuring out how to wire this by using Google.
The Shot Blaster:
cord colours
brown = hot
bleu = netural
green with yellow stripes = ground

.
The Dryer outlet is two hots and one ground.
Red & Black wires are Hot, and Green is Ground.
.
So, I'm going to keep searching to reaffirmed the answers I'm finding, but it appears I just need to hook up the shot blaster's yellow&green striped wire to Ground, and the Brown & Blue wires can go to either of the hot prongs on the Dryer Cord.
.
And if someone was doing 110v, it would be;
Blue = White
Brown = Black
Green Yellow = Green

[LostMy65]

More I've found;
Blue and brown as your 2 hot legs
Yellow/green as your ground.
And;
brown is hot(US Black), blue(US
White) is neutral, and green is always
ground.
.
But for 220v blue and brown are both hot.
Green is Ground.

dryers i've seen use 120 for the drum rolling\the other 120 is for the heat coil
the plug has red/black/white/ground
I've run compressors 220 by not using the white/com,just the red/black
