gandalf -
Thank you very much for the description. That is pretty much how I was testing it. I use Pr0tel 99SE, so should be able to open your sch.
The cup that holds the magnet for the fan (ventilator ! aha !) has the secondary winding around it. If it is metal, the metal will short-circuit the field from the primary, and no power will go across.
This is what I've seen myself. Secondary around a metal cup - I see good voltage at the secondary, but not enough current to light LEDs.
Yet Henk does exactly that - secondary around a metal cup. His forum describes this, and he doesn't know why it *does* work for him. Strange.
What frequency did you find to work best ?
Cheers -
