Low RPM High Voltage Generator For Wind Power?

[TommeyLReed]

Hi All,

This is a experiment using a secondary winding from a microwave transformer to create higher voltage at very low rpms

If you connect LEDs back to back then you will get conduction on both halves of each electrical cycle.  A FWB as you noted is another option.

I tried this some time ago
with a small DC motor to drive the pulley.
I learned in a practical way what is the Lorentz force and the  Lenz law that applies.

Leds work with few miliamps, and when  using a greater load (in this setup) there is toooooo much drag.
Its OK for learning.

Good to get learnt. Useful. But it is still not easy to get bulk commercial.

We are thinking the right way to raise voltage at low rpm, generally by adjusting the core. But it makes efficiency lower.

Our generators PM for wind/water energy use, see at:
