Have an old front-load clothes washer and some PVC pipe lying around? Make a vertical wind generator and go GREEN the DIY way.
Step 1: Remove motor from washing machine
This step was the most destructive using various implements to separate the motor assembly from the washing machine. I'll leave it to your imagination and whatever tools you have on hand. The output of this step should be the coil assembly and the magnet assembly. Keep the shaft and bearings if you can also. Mine were pressed into the washing drum and were difficult to remove without destroying them. Keep the bolts from the coil and magnet assembly also. You may want to use them for your new hub.
