What's inside your homemade WTs Joe ?
treadmill or servo motors ?
The gray one is an amtek 30, the black one is a bodine dc motor from a mail sorting machine similar to a treadmill motor but a little better, have one with a fisher paykel motor as well but took that one apart to put in an aluminum housing. Those fisher paykel motors are awesome if you ever get one. There from Australia so maybe Peter can send you one. A lot of good info on thebackshed.com. What are you using?
I've a few commercial big bucks 6Kw machines running - but it's more entertaining trying to emulate their output for a fraction of the cost - I've been doing this on and off for a fair while - those tape drive amteks and F&Ps are good for a few hundred watts into a battery, but folks tend not to build the chassis's to survive all weathers, or misscalculate the furling, or the TSR - much of what gets built is just hobby fun stuff - the Olson bloke knows one end of a lathe from the other -I've also done the big axial flux thing (magnets rust and detact after a few years) - I've a few that have been running for an age now, using commercial PMGs in own built chassis's- some grid tie (mix of 2 and 3 blades) others for high amps 48v charging. Most of the commercial PMGs need bearing helpers (or annual bearing changes) so I've a chassis that gets over that issue - if it works I'll post a few images of the PMGs I'm currently working with - these are ex MiniWind grid tie 550v @400rpm 3000w - combined with Futurenergy blades - in a bearing helper chassis.
Multi quote hell - I'll try adding more images after another post has been made as it's not liking more than two per post - sorry folks, wind turbines are way more interesting than fuses
