Help wiring blower

Recommended Posts

Hello,

I just purchased a  used windjammer blower and an electronic signal generator to use for smelting, but I need help-  I know very little about wiring electronics. Link removed I understand  the signal  generator needs it own power supply, but  I'm confused about what is needs to work and how to hook up that power  supply to the device. Would something like this work? Likewise, I don't know  which of the blower wires should connect to what on the signal generator. Will the blower  get all of its power through the signal generator? Here is the diagram for the blower.  Any help would be greatly appreciated.

If you have to ask if a 24V DC transformer will run a 120V AC blower, when all the info is right in front of you,  I  suggest you hire it out, wont cost much, in fact the cost will be less than wiring it up wrong

Smelting?  You will be turning ore into metal?  Which ore do you plan to use?

Yes, I figured out immediately after asking that i do indeed need to hook up the AC-input for the blower separate from the generator.

SLowly answering all my own questions. Just found an old laptop charger and stripped the wires to give power to the generator: worked like c  charm. Found  out from the company which wires are what based on color. Now I just to give the blower power.

small one....Though I spent over a decade as one of the hand crank blower thralls on bloomeries at Pennsic.

oh, very cool. I didn't know Pennsic has bloomery smelts. What do you mean by "small one"? The  blower was smaller in size then I expected when I received it. However, I believe the specs are up to par for a bloomery smelt. We'll see soon I guess.

I don't know if they still do; but we did them onside for over a decade; in the early years we would dig the clay from the creek. Starting out we had very poor yields; but by the end we were getting 15 pound blooms from a short stack scandanavian bloomery.  Flaxy and Steve even presented on it at the academic IronMasters Conference!

Oh, very cool!  Awesome that you were able to get it to work with hand  dug clay. That's a future step for me. Right now I'm using clay of a known composition.

Our later mix was a 3:2:1 cobb: 3 shovels full of sandy silty soil (onsite); 2 headsized bundles of chopped straw, 1 shovelful of powdered clay (animal feed additive) mixed with so little water is was absolutely painful to work---looked like muddy straw but it worked the best of all the others we tried.  One year we even used bellows: fast turnover in bellows thralls and one person was dedicated to putting out sparks that rained down on the bellows thrall.

You've been reading the Rockbridge bloomery pages I hope.

I've also found that I know the clay is good when it hurts to work. I like the term bellows thrall, hah. 

I have read the rockbridge bloomery stuff- Lee is the person who taught me this stuff.

Often as not bouncing questions off of others solidifies the concepts in your mind and you end up answering your own questions. Most of us want to help but it’s more satisfying to see the light go on than give you all the answers.

I would rather figure it out on my own- but in this case I really know very little about this stuff and a push in the right direction can be really helpful for me to even know where  to  start looking.first configuration. However, it only runs at full blast and the sig-gen dial does nothing until I turn it way down and then the blower cuts out and wont go on again until the power plug is turned on and off again.  With the blue wire on  "OV"  andthered  on  "0-10v"  the motor just starts  to run and then cuts out.

Something doesn't seem right. Thoughts?

woops, the previous post is supposed to read"

I tried hooking up the blower and I'm having trouble. I'm wondering if the blower's electronics are shot. The only way I can get the blower to run is in the first configuration. However, it only runs at full blast and the sig-gen dial does nothing until I turn it way down and then the blower cuts out and wont go on again until the power plug is turned on and off again.  With the blue wire on  "OV"  and the red  on  "0-10v"  the motor just starts  to run and then cuts out.

Well, with the blue (low supposedly) connected to "OV" and red (high supposedly) connected to "0-10V" the blower actually does slow down from 10V down to about just under 7V. After that it just turns off... bad blower electronics? bad signal generator? I'm baffled.

why do you expect a 120 volt motor to run at 7 volts? I am confused

It's running on it's own 120V AC line- but it has a DC control panel that accepts 0-10vdc for speed control. This is the input that is acting up.

Steve, the motor does have a 120v ac input. And if read this right its a dc motor. So that 120v  would get rectified into dc inside the blower. From there an electronic speed controller (esc) in the blower controls the speed of the blower. The esc get its control signal from his signal generator. The lower the signal voltage the slower the blower. The higher the signal voltage the faster the blower. Looks like a treadmill configuration. You plug a treadmill into your outlet but its really just powering a big dc motor.      Edennis,  I see in the  blower diagram there is a mechanical wiring diagram that would eleminate your sig. gen. It says you can set the blower speed through a potentiometer in the blower.  Try that configuration and see if you can raise and lower the the speed with the potentiometer.. If that works, it might be your sig. gen is not compatable or your wiring it wrong.

I dont see where it shows what the range is for the control voltage?

Thanks for the reply. I believe a different blower model has the mechanical speed control, while mine is strictly electronic. If you scroll down on  the specs page for  the blower is shows different models having different types of speed control.  I'm pretty sure the sig-gen is compatible since someone over on the bladesmithforum has used these exact pieces together- but you never know. It feels like the wiring is incorrect to me, but  I can't think of any other configuration to put them in. I'm scared to try hooking the blue/red wires to the AC input as I don't want to fry the blower (hoping I already havn't!). Maybe the sig-gen  is busted... but I'm out of ideas at this point.
