Lenz2 wind turbine

Step 11 Mount the turbine to the generator

Somehow you will have to mount the turbine to a generator or possibly some sort of support framework that will let it spin freely. In this project I mounted it to a 24 volt DC motor that I had saved from a battery-operated lawnmower. The motor was used to spin the blade of the lawn mower.

The motor has plus and minus spade connectors at one end and a shaft protruding from the other end. Unfortunately the shaft was half inch in diameter with fine thread. This makes it very difficult to mate with something like an allthread bar with is half inch coarse thread.

The way I solved the problem is to bolt an L-shaped bracket to the shaft of the motor. Then I used a piece of metal that I had saved from an old tiller. It is U-shaped and has holes on the side and a threaded hole on the top. The threading is half inch coarse thread, just perfect for mounting the allthread bar. Finally, bolted the U-shaped connector to the L-bracket.

I cut a hole in a piece of plywood large enough to insert the motor. After inserting the motor to the plywood, I bolted it down. To try out the turbine, I placed the whole affair on top of a heavy wooden box.

Nice project. I just love how people do totally inappropriate stuff in their pristine carpeted living rooms :) When lifting the generator up after taking pictures I would probably have a huge grease ring on the carpet :) Good Luck!
