32 volt DC fan
 

What are the chances of running a 32 volt DC 6 amp fan off a 6 volt system? It's a desk top style with variable speed and a 10" diameter fan.

I'd say slim to none...but it would look cool! :cool:

Re: 32 volt DC fan
 

Buy a step up converter from ebay. They are available in 5v to 24 volt which would probably work just fine. Get the 10a version. Pay attention to polarity!

And Slim left town.

Re: 32 volt DC fan
 

I wonder what it was originally designed to work with? If it has brushes, I'd think it should run, but at about 1/5 speed. Motors are typically rated by rpm/volt. (Kv is the motor velocity constant, measured in RPM per volt ). 6 volts just might not have enough "umph" to overcome the friction of all the mechanical parts.

Before REA came to the farms, a lot of the farms had their own 32 volt light plants, either wind chargers or gas engines. Remember Green Acres with the smoking vibrating light plant Oliver had running for Lisa. That was a 32 volt Delco Light Plant, but of course the smoking and vibrating was fake. The common size Delco has a 2 1/2" bore and 5 inch stroke, and are built to last forever, with a weight of probably about 200 to 300 pounds.

Re: 32 volt DC fan
 

I must'have learned from a different school,as for motors are rated by HP. Meaning 1 Hp.= 746 watts.(watts law = watts divided by volts will tell you how many amps the motor would draw). The higher the voltage the lower the amps .so if you run the motor with less volt the motor will draw more amps if it draws more amp than the wires or windings can handle they will heat up and will short out

Re: 32 volt DC fan
 

I need some schooling on ohms,volts, watts, and amps !! Never thought this Model A fetish of mine would be so complicated. So it looks like a converter or the Delco light plant in the back end. Thanks all !

Re: 32 volt DC fan
 

You got it!!!!

Re: 32 volt DC fan
 

No no no! :) The motor doesn't determine it's own load (amps), although there is a "no-load" rating.

Re: 32 volt DC fan
 

It's hp. Rating . The nec. Section 430 motor section will show you the facts .this is a section will show you all you need to know,that hp rating voltage will give you current draw.

Re: 32 volt DC fan
 

Uh? you figure if I put 1 volt through the fan it draws 750 amps?:eek:. I think Not. Well, not this side of the pond anyway;).

Re: 32 volt DC fan
 

Ahhh, the warm look back . . . .
Right now, and for the last twenty years, I have used 18 volt Solar Panels to charge my bank of 12 Volt batteries, which run the electrical system of my remote ranch.

However, in the twenty years before that, my bank of 12 volt batteries were charged by a Jacobs Wind Turbine, circa 1942 - one of the last of its kind, having begun production around 1924 or so. The Jacobs produced 32 Volts of Direct Current (DC) electricity. Prior to the expansion after WW11 of 'Grid' electricity (110-120 AC), rural America lived on either kerosene or 32 Volt D.C. electricity. In the 1920's, 1930's and 1940's, because so much of rural America lived with 32 Volt D.C. electricity, there were a great many products sold in every rural store and catalog in America - that ran on 32 V.DC.

With the widespread influence (driven by a U.S. Government program of 'Rural Electrification') of 'modern' (and MUCH more efficient) 110-120 AC electricity, slowly the 32 Volt DC products and the 32 V.DC generators that powered them, began to fade from the market place and the rural 'homesteads'. By the time I was using my Jacobs 32 V.DC there were only two products still being made the ran on 32 V.DC.

So I reconfigured my Battery Bank to continue taking in 32 V.DC from the Jacobs Generator, BUT reconfigured the Battery Bank Out Flow to the more common 12 V. DC. Because of the trucking industry and later the emerging RV markets, there were a great many 12 V.DC products that replaced the 32 V.DC products. And that is what I still use today.

Re: 32 volt DC fan
 

No, that won't happen because the resistance of the motor windings does not change. Amps = volts/resistance, so half the voltage will result in half the current if the resistance is the same.

Re: 32 volt DC fan
 

If you want a fan why not get a 6 volt one? There are plenty out there.

Re: 32 volt DC fan
 

I don't think he wants a fan. I think he wants to incorporate a vintage piece of history into his vintage automobile. It helps re-inforce the whole historical connection. And I salute him for that !

Re: 32 volt DC fan
 

I have an old small 6 volt fan, but this one is a larger blade fan by far and matches the period for quality. It is also a family heirloom that I want in my truck someday. Thought it might be an easy fix, but I guess nothing is easy !

Re: 32 volt DC fan
 

OK, since you have a truck, that solves the problem. You put the Delco 32 volt light plant in the back of the truck and run it to power the fan. You'll be the hit of the show wherever you go.:D

Re: 32 volt DC fan
 

Doug Vieyra and Tom Wesenberg know this history of 32-volt systems. Jacobs initially made 32-volt wind generators before REA, and later 110-volt wind generators, but the standard in rural America in the 30s was 32 volts.

As for the look you want, I'm guessing its mostly fan blades and the wire cage. You might take it in to an auto parts store and see what they might have in a 6-volt or 12-volt heater motor that you could swap out, retaining the blade and cage.

Re: 32 volt DC fan
 

Definitely on my list of things to do now Tom !! Guess i'll have to look for more 32 volt appliances now :eek:

Re: 32 volt DC fan
 

Thanks for the delco light plant lesson, can't believe I've never heard of it before. Some good youtube stuff about them... would love to have one to play with.

BTW, where would you put such a large fan in the small cab of a Model A pickup?

Re: 32 volt DC fan
 

Passenger floor blowing up at me !! Wife could ride in the back and keep the Delcolight running:D !!

Re: 32 volt DC fan
 

Art, I was hoping to mount it between the E brake and seat, but like you said small cab. Checked where you live (Bellingham). I've never been north of Seattle and that area looks beautiful !! This summer I went out to Centralia, Wa. and picked up a load of stuff. In the spring/summer I need to go out for more. How far are you from Seattle? I would love to drive through that area. Thanks, Pat P.S. Dick lives there too !! Has to be a great place to live !

32 volt Delco Light Plant info

Here is one on Ebay; http://www.ebay.com/itm/391651609107

Re: 32 volt DC fan
 

Looks like I would need the express box and a few extra leafs to accommodate 16- 2 volt batteries ? :confused:

Re: 32 volt DC fan
 

A good 'Deep Cycle' battery (6 volts) weighs 115 lbs. When I was using 32 V.DC power for my electricity needs, I used 6 each 6 V.DC batteries in series. The 6x115 lbs. did indeed weigh quiet a bit - 690 pounds.


I usually had my wife move them when they had to be moved.

Pretty sad for a guy that works out with QUOTE. bar-bells, dumb-bells, pull-ups, push-ups, arm wrestling, and pulling the starter rope on my lawn mower. .QUOTE:D:Dlolol

Re: 32 volt DC fan
 

I've had to resist making the trip to Centralia, Looks like you got some good stuff! We're still a 100 miles north of Seattle, only about 20 minutes south of the boarder. We are planning a drive to Mt. Baker in August. I've been building a simple web page for our club, watch there for the details. www.moonona.org

Re: 32 volt DC fan
 

Will keep in touch and have a great trip. I'm planning on joining a Model A club in Minnesota this spring. Art, talking to A guys is like hanging out at the old hardware store !! Checked out the pictures of Mt. Baker, stunning and I need to see that !

Re: 32 volt DC fan
 

This is an accessory for the light plant. I believe it is a motor to run various things in and out of the house. Churn, washing machine, or grinding wheel. Delco light in the fore ground and I believe it is a model 752. Temp. here today is unknown even though the Humidity looks good :)

Re: 32 volt DC fan
 

Unknown... but looks very cold!

Re: 32 volt DC fan
 

Art, was just reading your post on your engine check by completely pulling everything apart !! Don't tell me how it ends, I'll read the rest later :) Getting ready to start pulling one apart today to learn some of what you learned. 21 degrees here right now. Great day to you !!

Re: 32 volt DC fan
 

Thanks, for the info 1930 coupe ! I have a small 6 volt Chief fan now, but I thought it might like it's mom close by:eek: I will start only posting Model A stuff on this site though. I had a fantastic day in the shop. I learned my junk motor was rebuilt at some point and is possibly the original motor to the frame:eek: Frame is solid motor mount which ended Dec 28, engine # is Nov 28 and has front cover to match mount. Love you guys !!!!!

Re: 32 volt DC fan
 

I hope to have it running on a stand soon. I plan on videoing the start up. Gotta find a fuel tank of some kind.

Re: 32 volt DC fan
 

I have a few tanks over here, if you want to pick it up on your way through:eek:
Will be checking in for help on my venture if you don't mind ? How many have you built ?

Re: 32 volt DC fan
 

I just need a tank for the engine stand. I'd help anyway I could, but I'm a Model A noobie!:D

Re: 32 volt DC fan
 

Solder a copper nipple to an empty 1 gallon metal paint thinner can, which many body shops throw away. This makes a good fuel tank, or you can usually find a tank at a small engine shop.

Re: 32 volt DC fan
 

This only applies if the motor is stalled or just starting. Back EMF is your friend. Saves lots of amps.;)
