nice idea but to generate like 200 watt on a bike still is A LOT of work. You'll be peddling like crazy

I think the point he was making is that this device takes the input power (peddling) and multiplies it (torque at rear wheel). So no matter how hard you peddle the motor is always putting out more energy then you are. I would agree that would be an great way to apply a device like this. It would make commuting by bike that much easier for the world and depending on the power ratio achieved by refinement of the technology, who knows... Maybe a AC alternator on the front wheel could generate enough power to run the real wheel, meaning, no peddling at all. That is what overunity means in the long run. If the a device is indeed overunity all things are possible with enough time and research...

Hi Jack,

I tried to model your valve in FEMM 4.0,  I also modeled it with the magnet replaced with iron of the same dimensions, There was hardly a difference in force with or without the magnet in the valve.

I get the feeling this would not be so in a real life situation. You could machine a block of iron the same size as your magnet, replace it in the valve and see how much force it has with the same amount of power applied.

Lovely motors by the way, You are a real craftsman.

Hi Jack,

Here are some images from FEMM of your valve, the first image is the valve with magnet
size 3 inches square, the iron side pieces are 3 inches by 1.5 inches. The rectangles either side of the iron side pieces represent the coil (10000 turns, 0.8 Amps, 35.6 Volts, 28.5 Watts). With magnet(NdFeB 40) the force on the side bar is 2985.5 Newtons with a 0.2 inch air gap.



The next pic is the valve with the magnet replaced with a piece of iron, same circuit properties, the force on the side bar is 2982.1 Newtons with 0.2 inch air gap.






here is the valve with the circuit off.



It could be that I've missed something in the modelling of your valve(highly likely). Or FEMM simply can't model this kind of problem, I don't know.

best regards

Great pictures.
I believe you should not have used 28.5 watts in your simulation.
It might "hide" the effect of the neomag when its released by 8 to 10 watts.
Try simulate it using lower wattage. Perhaps it will behave differently.

But most probably FEMM can't model this type of design, as you say.
A computer simulation is never better than the person who programed it.
Magnet Power equals Clean Power
