hub motor wind turbine
Submitted by bizybily on Sun, 04/05/2009 - 10:57
I am trying to use my wilderness energy 36 volt hub motor as a wind generator but I don't know if i'm hooking it up wright. I have 3 wires comming out and no matter what combination I use I get AC voltage. Does any one know how I have to hook this to a rectifier to get DC voltage?

bridge rectifier? http://en.wikipedia.org/wiki/Diode_bridge

Re: hub motor wind turbine
Thanks,
I knew I had to use a rectifier. About 2 months ago I used a rectifier out of a gm alternator and everything was o.k. but I'm not sure how I had everything hooked up. As I said, there are 3 wires comming out and they are all the same. No matter which of the 3 wires I use I have continuity and ac voltage. Where's my negative or common wire?
Am I missing somethig?
Re: hub motor wind turbine
the 3 wires are three phase wired in delta.
they are *all* actives/lives. there is no common/neutral.
you need a 3-phase bridge rectifier.
this will be composed of 6 rectifier diodes (as oppposed to 4 for a single phase rectifier)

Thanks,
Every thing is working fine. I was not spinning it fast enough.

Out put current can be charged to DC current?which is attached to electric scooter.
Re: hub motor wind turbine
though yes this is possible, theres no point.
its a perpetual motion machine attempt, and will fail like all before it.
useful energy out is *always* less than useful energy in.
