Lenz 2 with new larger 12 inch alternator installed running

This is the Lenz 2 on the dock with the new 12 inch alternator. The alternator is a little to much for the wings and it won't counter rotate right now. It is still charging because one section is going faster than the other. I am going to tie off the bottom section for now after this video. I will have to either open up the air gap on the rotors or flip the bottom wings so they go the same as the top and tie both together for more wing area. I'll have to make the Rotor stationary again then and not have counter rotation if I do that. Will try the air gap first though. Opening the air gap helped. I have both wings going the same direction now and tied together. I'm getting 3 to 5 amps in around 17 to 19 mph winds right now. I'm not sure how accurate the amp gauge is. Looks like I'm getting around 120 RPM's. Still going to do more experimenting. Maybe extend wings out more. I'll have to build a wider frame.

extending the wings would slow down the RPM's. This is the first good wind I've had to see how it would act. I don't think it will be hard to get it tuned in for a decent charge. Opening the space between the magnet plates will make it turn easier so the wind should be able to spin it. I can make that change fairly easy. or make it just one directional rotation by tying the 2 wings together. I just have to flip them end for end and fasten to the bottom shaft. More wing area, more power.

@wiboater4 I will have to make the stator stationary again if I connect the two wings as one. That's fairly easy to do also.

I was wondering. If you extended the arms out that hold the bottom rotor, would that not give the bottom wings a little more leverage and then be able to over come the resistance a little more. I would imagine that since it's on the bottom there is a little less air flow as well as a little more load on the bearings so that's why it's a little slower. ?? Does that make sense?

@Keveeee2000 The wings need to be exactly the same for it to counter rotate. I just opened up the air gap on the rotors a little. Now just need to get some wind again to see if it's enough. Seems better but really light wind right now.

Ah I see. Well that sounds like an easy way to tinker with the tuning.

Thanks again for posting this kind of thing. I'm learning a lot!

It looks like you have another great project going on. nice Lenz
