re-purpose a 220 fan

[akpolaris]

I have a fan that I pulled out of an old 3 phase welder a while back. the plate on it indicates that it is 220 and there are 2 wires to power it up. They look like 16 gauge. My thought was to use it as a vent fan in the wall or temporarily in a window hole. Is this possible? Can it be run on a 110 circuit of do I need to dedicate 2 breaker spaces in the box? Or just bag the whole idea?

Depending on the motor, and if is on a residential occupancy, it may not be permitted to use a 240 volt item.

Yeah my guess would be that its a 1ph 240v motor. Do you have a picture of it?
It might be easier to scrounge up an old squirrel cage blower from a furnace to rig up,it would move a lot more air Im pretty sure.

Need more information/too little info to go on.

Post a pic of the nameplate or brand and model number.

 

[Norcal]

See NEC article 210.6(A)(2), which what I alluded to in the other post, if it is a cord & plug connected load of 1440 volt-amperes or less then 1/4 HP the voltage cannot exceed 120 volts. This is a residential requirement.

Hopefully this upload of the motor works

Too blurry. Cant read it

Thats a lot bigger motor than I was expecting,how big was the welder?

Looks like one of our motors. If you can get me the model number on the nameplate, I may be able to get you a wiring diagram. The model should be something like K55HXPMH-7511

It is an Emerson Mod #F48DZP-2106, volt 230, RPM 1550, HZ 60/50,, amp 1.5, HP 1/12. Hopefully this picture is readable

Thanks, that is shaded pole motor made for Miller Electric. Appears to be built in 1989 based on the date code.

This is a non-reversible motor is designed for 230V only. Should be pretty easy to wire, just connect L1 and L2 to a 230V circuit. Note that this motor is grounded via the housing, so you'd need to make sure the fan assembly is grounded properly.

As an FYI if you wired it for 115V, it would run slowly for a short time, then the magic smoke would escape....

Unfortunately As Norcal pointed out in #5, since its 1/12 HP it cant be used in a residence.

Where do u want to use it?

 

[akpolaris]

My idea was to use it to ventilate a shop building. Get the welding smoke out. I wanted to make a frame and mount it in a window (about 10' up) and switch it to use when desired. Back to original question... the window is on opposite side of bld from breaker box. If it needs to use 2 spaces on the panel and run wire heaver than 12 guage I can hang on and look for something else.

Well then since its not in a residence youre fine.

How long is the run?

Yes u will need a DP breaker. The motor is 240v.

Is the breaker panel full?

 

[akpolaris]

Plenty of room on the panel. I need a dedicated circuit? It is about 50' going up and across the ceiling or around the wall. what size dp breaker? can it run on 12 guage, I have plenty due to that is what I am wiring the shop with.

 

[wyliesdiesels]

Does the motor have an overload?

Yes #12 is fine.

 

[Freejack]

That motor does have an automatic thermal overload.

While the letter of the law allows it this is a poor idea for a little bitty fan, why not find something that is 120V that will plug to the nearest circuit. A simple little box fan does the same thing vs designing and all the associated work for so little net in the end.
This would be different if it was 12 A over 100 ft but is an exercise in mental ************ for the most compulsive of junk collectors.
I really got to wonder sometimes about masters giving a big atta boy to brain farts like this and that's not intended to insult the OP but a frickin reality check here.

Or just bag the whole idea?

This is the only good advice for this.

 

[akpolaris]

sberry, noted. It appears that while it can be done going with properly designed materials is a lot easier. And I acknowledge that i do collect junk and try to cobble it together.

 

[sberry]

Yes, that wasn't jabbed at you but to some guys that should know better. The question was good.
I don't know what the demand is but that might be something to list for sale. Especially if you had the model of the machine it came from.

I agree however even when people are told something like this is a waste of time, the junk collector inside of them will do it anyway just to save a penny on the cost of the motor all while wasting a penny on the time it takes to design and rig it up.

 

[sberry]

If they are going to cobble it then its likely this whole thing wouldn't be code compliant anyway. Its not a bad idea to consider all the possible ways of doing it but as a practical idea its not only a waste of time but potentially dangerous.
This ranks up there with converting a dryer outlet to 120 to save running a cord for a few Halloween lights. The response to the idea should not be a how to,,, it could or should be be first and foremost not a fundamentally good idea followed by why.
I see a lot of masters very concerned about circuit requirements but once its poast that often seem to endorse a lot of un needed tampering that is no0t needed and introduces as many issues as it resolves.
