Building a Wind Turbine VAWT (19 of 46) drill mounting holes for optional 12V DC Motor

This turbine was designed to get the most out of direct drive PMA set-up (converted car alternator). However, there is no limit to the options that might be considered. There are very inexpensive DC motors that can be used as generators. I picked this one up for about $10 at a very popular auction site and it works. This turbine could be used to pump water and a small water pump could be mounted. Belt or gear drive systems to run a small generator at high speed could conceivable to mounted to this turbine.

With all these considerations in mind there is no way I can demonstrate how to mount every option out there. I will show how I mounted my PMA. With an alternator you can have your batteries much further away than you could with a DC motor generator. The problem with DC is the resistance in the wire will quickly consume all your energy over long distances. That can be offset, somewhat, with heavy gage wire at medium distances. The advantage of alternating current is it can travel further when minimal loss due to resistance. Then just a simple rectifier at the batteries coverts the AC to DC for charging purposes.
