Well, I stopped by and got this on my way through Florida.  It was available on Craigslist from this thread: http://www.afcaforum.com/forum2/49071.html

It is pretty nice. May build a pedestal fan out of it! It was a transformer cooling fan for a substation transformer. Will do a proper cleanup and video when I get home with it!

I was looking at the Krenz & Company transformer fans website and they have some familiar-looking aluminum blades available as replacement parts. These might be good alternatives to replace a broken blade on an older circulator fan. I have a feeling they are not cheap, but nothing worth having is cheap these days.

Here is the link: http://www.krenzvent.com/transformer-cooling-fans-parts-accessories/transformer-replacement-fan-blades

The 16" and 24" both look very nice, in my opinion.

By the looks of the data tag on your motor, which says 208-230 Volts 60 Hz, its a 3 phase motor and you'll definitely need a phase inverter like the ILGs used in order to run these on standard 110v Household current or you'll need to get an outlet wired into your house for 3 phase 208-230 Volts AC (which is NOT as easy as it sounds).

Levi, the tag is partially covered in that photo. It's a single phase motor with permanent-split-capacitor system.

Here is a video of my work on it today!

OK. I would of figured it would of been a 3 phase motor being that it was used to cool a power transformer because those power substations that they use those cooling fans for their transformers normally wouldn't have access to single phase power, single phase power is usually what you have in your house, not at a substation.

Any time I see a blade with a sickle shape I safely assume it's for noise reduction.  It's cool how your 4 wing is really 2 sets of 2.  Like a modern ming-esque blade.  Congrats David!

Thanks!  I was in the right place at the right time for this one. Took a side-trip on a training trip and got it.

Really, it is not loud at all considering how much air it moves!

I was thinking how neat it would be to mill another keyway in the motor shaft and install a third blade set!

Wouldn't that be going a little overboard putting a thrid prop-style blade on that fan?

Yes of course it would be! Delightfully overboard! :clap:  Just like a 48" Ilg shop fan or restoring a cotton gin blower! LOL :cool:

OK, Just checking, the only problem is that the prop-style blades offered by the company that made your fan aren't the same style as the blades that are currently on your fan so it would completely throw your fan off balance, so you would need to replace the other two sets of blades as well so that they all match up so the fan isn't off balance, which depending on how much their blades are might be a costly proposition.

I think he'd be fine with a 3rd bladeset.  Go hard or go home, right?!  Since we're going 2 blades at a time, weight distribution is balanced.  My only concern would be motor load, which I'll highlight is only minimal at that.

True, I think the motor would be able to pull it; however there isn't enough shaft length for the third blade set. It might be possible with some additional machining on the blades, but hey.... too many projects already!!!

I know, he already corrected me about his fans actually being single phase father than triple phase.

If you haven't already, check out some of his videos. He does some awesome work. A wizz with electricity!

Not corrected you!  Just up till that point the motor nameplate hadn't been shown. :cool: I also was expecting the fan to be 3-phase before I saw it.

Yep - 3-phase motors don't use a capacitor. (Note: not talking about power factor caps).  In Levi's defense; we had been discussing the fan on another thread in the buy/sell/trade area; where the original pictures didn't show the whole motor nameplate and the fact it has a capacitor. I also was expecting it to be 3-phase.

If you leave the guard off, David, you can probably feature this fan in the next SAW film.

LOL good point! Would need some sound effects, though because it's too quiet as-is.

Maybe over-dub the sound of this fan starting up.... Sounds like a "wye-delta" soft-start but has still enough inrush current to cause the lights to go off in the plant for a few moments! https://www.youtube.com/watch?v=aMVzrMJ_P-U

In fact, the fact that it says "230" indicates that it is a single phase motor.

In a 3 phase, 208 volt system, you will see 208 volts between any two legs, and 120 volts between any leg and ground or neutral. Single phase machines can be run from this type of service by selecting the appropriate connection between hot legs and neutral. Motors designed for 230 volts will run with slightly reduced capacity on 208 volts.

It's all about the phase angle. ;)

I thought it was" all about the base, 'bout the base, no treble". Lol. Couldn't resist.
