Confirming the Delayed Lenz Effect

[DeepCut]

I'd imagine the centre hole isn't necessary but may be useful if you want to stop the magnet rotating by putting some threaded brass (non magnetic) rod through it and clamping it with nuts and washers.

@ syncro1,
I've tried it with solid mags, i got more power out but with more drag, maybe my configuration isn't right...


@Dc,
Thanks for the info.

Try speeding the rotor up! You're below threshold r.p.m.

Try speeding the rotor up! Your below threshold r.p.m.

My rotor is 12 inch dia. With 8 1"x1/2" mags, i think i need to add more magnets or cut the rotor to a smaller size? What do u think guys...


P.s. my rotor speed is about 1,500 rpm.

The important thing is the frequency the coils are being pulsed at by the magnets.

Your rotor has 8 magnets and is doing 1,500 RPM so the frequency is :

RPM/60 x number of magnets

= 1500/60 (25) x 8 = 200 Hertz.

Good results are to be had from about 400Hz up.

You need to double the frequency by either doubling the number of magnets or doubling the RPM.

I have done some spreadsheets and a couple of programs that you may find handy, let me get the links and i'll post it for you with explanations.


All the best,

DC.
