thanks Tom, interested in hearing how yours works. BlueJay, I agree with you that there must be some loss due to power being shared within the bank. What I was wondering was, due to a larger bank with more amp hrs being stored, would or could that create more load for the turbine or is 12 V,, just 12 V. regardless of the size of the storage ? thanks, murray
Got some wind this morning. tried a car battery and a garden tractor battery. Got noise both times. So I would take it that battery bank size really does not matter.
Just got an e-mail from the USA company that I ordered the gauge from. May take longer than 30 days to arrive. This is an international delivery. :evil: Also unhooked all the wires and the turbine still makes noise. I will check amps with wind today but it will be coming down. At least for a bearing check. If no amps I will be sending back. :cry:
Tom I think it is good that you are zeroing in on the turbine itself. If there is a bearing or inner wiring issue at least Windy has already offered a replacement. For me, I just figured it was not the external wiring as so many of us were using 12 * 3 wire at long distances with no issues. To my question regarding bank load. you have a good size battery bank as well, so what I was wondering when Windy does a test and if they are using one 12 V battery the load is limited in amp hrs storage, some of our other forum members may also be using only one battery and can fill it with ease, while others are using a larger amp hour bank and of course it takes more power to fill it. So is there less load on the turbine that only has to feed a one battery bank rather than many ? Just wondering if the upcoming Windy test will be relevant to us who are using a larger bank. might be a dump question but will put my mind to rest just hearing a response. murray
darn, forgot to explain the question properly. :roll: If there is more load on the turbine when feeding a larger bank, could that require a higher wind speed to create the same Volts being produced to feed a small bank ? ( if the small bank is offering less load to the turbine ) murray
Let me rephrase it. At the same wind speed. I got no difference in amps if it was hooked to 530 amp hrs battery bank or car battery or garden tractor battery.
Yesterday did not go well. We were short on time so we went to a desserted road that is much closer to our shop. The problem was the road was too bumpy for the turbine to spin smoothly. Everytime we hit a bump, it would shake the pole/turbine and the amps we jump all over place. The shaking of the pole really slowed the turbine down. It was pretty much a big waste of time setting everything up, only to find out the road made it impossible to do any testing. I am going to try to do it tomorrow if there is time. This week is really busy. I am going out of town from Thursday to Sunday and there is so much to get done before I leave. I will keep you updated.
I finally got it down. These are the pictures of what I had to get it up and down at my location. Also I used the Ridgid cordless drill to turn it and got 0 amps. Heavy load right at start up. The gear reduction drill goes like 240 rpm and the amp gauge picture shows the amps. I think by the torque this thing needs it would need 8-10ft blades to turn it if I could get the speed out of them.

Sorry about rpms I just counted and it is closer to 150 not 240. 240 is what it is rated at but with the torque it is only 150 rpm.
Windy, I checked a picture on utube and I shows sealed bearings in the unit . Mine came with shielded bearings with no seals. Water got into the bearings and made them noisy. Also the magnets were not coved completely with epoxy and had heavy rust on them and there was rust dust built up all over the magnets. You guys need to get on the MFG about this or there is going to be more trouble with these units.

hmm no if those ends are alternating poles then the end doughnut would actually cancel out magnetic fields... I did some reading and if a N pole is over a coil and a S pole also is over the same coil it will actually reduce power output.I see building something in the future.. I wonder if the magnets in these motors are magnetized end to end or thru the thickness?
I just went to the shop. I was going to be absolutely shocked if we had shielded bearings. I opened up a couple of units (four to be exact) and they all had sealed bearings. The blue coating is longer used but it does work well. We now use a even better coating which you can see in the photos. Did you by any chance due anything to your PMA before you painted it? Also, do you have the newer PMA with the stainless steel caps? I am just trying to figure out how that much water even entered the PMA. My guess is that the factory accidentally sent us a generator that was designed for a different purpose and/or a different customer and did not have the necessary protection for outdoor use. Hence, the shielded bearings. We will send you a new PMA tomorrow. I am starting to wonder if a forum was a good idea.....

Windy, I already bought varnish and bearings for this unit. Was going to try and fix it rather than pay shipping to send it back. I also removed the plate and welded a 1/2 inch sleeve to it to make the connection water proof before I put it up. The magnets are good and it cleaned up well. But from what I read it will take a week for the varnish to cure. After curing I was thinking of wrapping it with tyvek paper to install the stator. Then pull it out and install the end cap. Did you want the old one back? If not will keep working on this one and report back. Will test side by side to see how much of a difference there is. Then I will report back. I posted on yahoo answers about the rust causing drag and have one response so far with a yes.
Windy, Also for the record. No water proofing on the windings. [attachment=2:31i8h099]Windings.JPG[/attachment:31i8h099] [attachment=1:31i8h099]PMABearings.JPG[/attachment:31i8h099] [attachment=0:31i8h099]RearCover.JPG[/attachment:31i8h099]
A forum is not a good idea what? :?: If you have a inferior product and people are actually wanting you to make it better via a forum. That is a blessing.. I heard no tongue lashing out towards you windy,The problem was brought to you in professional manner. this way you can handle it quickly and it shows that you are commited to what you offer. No one is trying to slander and bash the site..If all this testing of cord lenths and the other concerns is not addressed how will we have find the answers? I see a few people on here that could potentially have valuable knowledge that will drive AFFORDABLE wind technology for the home.
