Electric generator

Hello
I'm not sure if you know this Swiss company,
but in doubt here is the link, it may interest some of you.

HS link

Is this a joke ???

If it is a scam they could at least have taken a graphic designer to do the photo montages:



More seriously, I am not good enough in German to understand ... One more "magnetic motor" or an advanced alternator ??

[Cuicui]

What ? If I understood correctly, it is a dynamo which consumes only 5 W for the cyclist. Not enough to whip a cat.

[delnoram]

no it's not a scam

for having an "old" model in hand, I can tell you that it turns almost alone.
An impulse between 2 fingers and it turns well around forty seconds

Nothing to do with our bike dynamo

[Christophe]

There they speak of generator up to 2 kw ... it's a bit big for a dynamo not

[delnoram]

you think

if you put the fridge on the luggage rack ........

Yes, but with what load? because empty, it's normal that it turns freely, it's the least things ...

Very good question.
the trouble is that i didn't have enough time for more complete testing.

So here is the only test I could do:
speed of rotation 6500 rpm obtained by friction of the "head" of the dynamo on the shaft (smooth) of a colone drill.
the generator hand-held for testing.
Result of lighting a halogen spot 12volt 35w (light obtained more than correct).

that's not much but that's all i could do in 10 minutes

The difference with a standard dynamo is the absence of metallic masses on the "support of the coils".

[Christophe]

This does not tell us anything about the performance of the system ... have you measured the power drawn by your drill?

[delnoram]

not of course (and considering the age of the beast I am not sure that are yield is extra).

The fact remains that the adhesion of the rubber of the head on a smooth metal axis and not degreased and held with one hand (the axis-head ratio being 3) gives a looking idea of ​​the couple.
