Hello LGO46 and welcome to the forum. You will need to spin the motor with a lath, drill press, or maybe just a big drill to see what speed it will start makeing 24 volt. If it takes alot of rpm to reach this, then a VAWT mill will more than likely not work for you. What is you'r average wind speed? (another big determineing factor), because you will need some good clean wind to run one and still expect to get a satisfing output. I would encourage you to do lots of reading on this subject "before" starting the building process. If you are located in the country I would suggest that you build a HAWT, much simpler and a proven preformer. Many who build a VAWT are disappointed with the poor output. Mac46 PS; There are several authors and builds on this site of both types. I'm just a farmer |
