Up and flying!
« on: February 23, 2009, 03:12:16 PM »
  2-23-2009 This is the second day the mill has been up. All day yesturday I only gained one hundreth of a volt. I went from 12.33 to 12.34v.

  This morning I checked voltage at 9:00am and it was 12.42v. So Ive made .09 hundreths gain in the night. We are supposed to have about five mph more winds today.

  The mill has a vibration right at cut in. I'm hoping that it can push through this and smooth on out after cut in. Yesturdays winds was just strong enough to reach cut in. Today it should get more above cut in today.

Is this the Alternator or the dc motor?

  Treadmill motor. One of the 260@5100. I have a six blade 60" set of blades and billet aluminum hub.

 You can charge a Six volt  run the the six volts in series with the Treadmill motor to cut in and chrage your 12volt load .

tecker, hi,


Can you explain in detail about 6 volt to 12, I cannot wrap my pea brain around this theory without help.


Thanks

  Shes charging fine at 12v. She ran along at 1.5a to 2.5a nearly all day long. It is seven o'clock and the winds died down for a little while. They blew about 15 to 20 all day. I may have had some spikes also that I'm now aware of. The batteries were at 12.56v. From 12.34v this morning. We are supposed to have twenty mph winds for the next two days so I'll get to see some more charging yet.

  What I've been worried about is a vibration shes had. But I think It is smoothing out some. Breaking in or sumpthing.

Hi


I think what Tecker is saying is to use two 6 volt batteries charge them as 6 volt, then series them to 12 volt for use.


I'm thinking you would do much better with a three blade prop with a high tsr. Your prop would reach a lot more RPM's. 6 blade props have lots of low wind power, But also have a lower top speed.


The sound you are hearing is when the generator starts working. If your blades  turn faster it should quite some-what.

You can do that also .But  a 6 volt will charge fine with your moderate winds  the treadmill motor will cut in at lower rpm and charge that battery . When that battery is at a good charge hook the neg of the 6 volt battery to the neg of the 12 volt battery and the positive of the 6 volt to the neg of the treadmill motor and the the postive of the 12 volt to the positive of the treadmill .After a while you can set up a dump load circuit that does this as the 6 volt get's fully charged . the neet part of this is with the added rpm the winds gusts and rises will carry the voltage past 18 volts and charge both as the 12 volt gets charged . When your ready for a dump circuit I 'll post a 1m317 circuit you can build with  few parts from the RAT shack . Remember your blocking diode . The bottom line is the if the tredmill can get above 8 volt the 6 volt won't really go flat ..

Sorry I forgot myself the treadmill pos lead the neg in a charge circuit

 My bad clockwise pos counter clockwise neg I think you know this but I am testing now for clarity and amp figures .I use this method to charge my 70 volt bank and my 6 volts batts are outside in the cold .I using a ragged out car batt on the bench now and that will that would be ok but it won't last long .

  Another day. Today is the 24th. Last night the volts was at 12.56. It was still running along at around 2.5a. Today they are calling for winds up to 15 MPH which is a little below cut in but the gusts might bump a little more juice to the batts.

  Mr.Tecker, I uploaded a pic of my control pannel to my user info. It shows my batts, isolator, dump-load, and switch box. No computer here, I have to manually switch from battery to dump-load. My dump-load is 4-55watt automotive hallogen spotlight bulbs mounted inside a computer power supply enclosure. The one in the picture with the big fan on the front. The isolator diod is in a heat-sink. It is the one up top. And of coarse my inverter. At the bottom you can see my T-105's. I'm going to go out and take a reading on the batteries as soon as I get a coupple cups of coffee in me. When I went to bed we had 23 MPH winds so the chances are good that I will see some more voltage.

Looks good take advantage of that good wind and post back I 've been thinking about this dump load to work with dc motors anyhow .I know of many amatek and treadmill related posts on this so I'll post a circuit that can be wired in series to plump up a 6 volt and then dump it  to charge a 12 volt as the treadmill and amatek only do well above 800 rpm car alts are in tha same range  but you can work with the star node to bring them into a lower rpm range .

  Cool, I am wondering how that works. This mornings volts was at 12.51. I guess the cold morning temps effected the levels. There hasnt been any battery usage since I stsrted charging. I want to see as full of a charge as possible before I start discharging any.

  For now I'm going to town. Yaaahee! I've got instructions from the wife to make one of my soups. Shes funded the venture gas and all. So take it easy and I'll post here again when I get to see some volts rising. I may not today, winds are just a tiny bit below cut in.

  Its noon and the temp has gone up 20 degrees. The NOAA weather service say 15MPH is the max we've seen from the wind and the amp meter says that power is moving. From 1a to 2.5a or so and battery volts read 12.61v as of noon. So I'm creating power at 15MPH. I think thats pretty OK. After all for a good solid charge ya need to charge slowly right?
