Confirming the Delayed Lenz Effect

[synchro1]

The pictures are out of order, but the descriptions identify them. The key element to this unit is the precision ceramic bearing from Bocas. I only use one in the center.

The coil pole of the bifilar is determined by the magnet pole facing it.

I'm in Costa Rica now away from the shop. Try reading from this thread:

@Gotoluc,

The C.D.'s just hold the coil in position over the magnet spinner. The r.p.m.'s are way over the switching speed for the Radio Shack reed switch. You have to manipulate the coil by moving it up, down and around to stay on the sweet spot!

Okay synchro1 thanks. Costa Rica is a beautiful place!

I'll read up on the topic.

Thanks for sharing

Thanks for adding that. I was also wondering how the reed switch can handle that kind of speed.

Hi DC,

good experiments you have going.
One thing I noticed is, the lower the resistance (load) on the shorted coil the less effect it has on the prime mover. You mentioned you have a bulb as load. That may go up to 10 ohms or more when lit. Try a 30 watt 1 ohm resistor instead. The coil may now have zero effect on the prime mover.
Let us know how that worked or if I have misunderstood your test.

Thanks for sharing

Hi Luc,

looking forward to when you have a lab up and running again

Your suggestion is good and would probably work, but i am working toward a coil that can cope with a wide range of loads, not just getting it to overspeed the rotor.


Cheers,

DC.

Thanks for the reply DC

Keep us updated of your findings.  My research shows that as resistance increases the positive effect decreases. Would love to see the opposite

Yes exactly, it's all in the time-constant of the coil, so the higher the resistance, the less retarded the TC is.

That's why i am aiming for a high TC of around 100ms.

Aside from the TC, as you know it's also the frequency you drive the coils at.

I've driven them from 200 to 500 Hertz and the effect just gets better, the stronger the CEMF, the stronger the effect.

One important point to note is that there is no cycle from acceleration-under-load to deceleration-under-load as the frequency is driven higher.

This is a very important point as it implies the effect is not solely due to CEMF peaking at just the right time, when the magnet is just at the right position.

The effect is happening regardless of magnet position at rise-time.

I've made a spreadsheet with it all there, the properties of the rotor and magnets as well as the mechanical maths to see how far a magnet would have travelled in x amount of TC units, anyone can use it for any rotor :

Some of my perspex has arrived, i can't begin testing until my coil plates arrive tho. Hopefully this weekend.


All the best,

DC.
