Magnic Light: contactless bicycle dynamo light
I am into it. Someone commented he tested with 2 and 3 cells, 2S 8V 450mA 3S 12,2V 670mA. That ofcourse is input, estimating an efficiency of 80% overall the motor would output ~6.5 W at that speed. Sounds good. We'll see what comes out of it when used as generator. I expect it to be close to...- manokaiser

Magnic Light: contactless bicycle dynamo light
So, after some initial thinking here is my idea of a really powerful light based on the principle. First take a look at this pretty little motor here : It has some very interesting features which I believe make it an ideal candidate for a generator. The plan is to attach it next to the braking...- manokaiser

Magnic Light: contactless bicycle dynamo light
Hi! Wikipedia has a very interesting picture here , in the article about eddy current. ( http://en.wikipedia.org/wiki/Eddy_current ) "A cross section through a linear motor placed above a thick aluminium slab. As thelinear induction motor's field pattern sweeps to the left, eddy currents are...- manokaiser
