Mostly Permanent Magnet Motor with minimal Input Power

[Khwartz]

Not sure to very inderstand the principle and the calculations for this kind of device; just be about giving true ideas onhow to demonstrate O.U. so that nobody could contest it.
Good luck for the rest of the quest

This an idea of a test set up for determining if any extra power can be achieved.
The leverage between input and output stages is 1:10.
Solenoid is in blue, and PM in red.
The stroke between the PM and solenoid ~1/4", which makes travel of the output ~2.5. This is where to attach the weight to lift.
If the magnet is not strong enough, to add another one, for a start 3" dia x 2" high.

Hi Luc,
was very excited looking at your videos - great work!
Just want to point out that in order to generate 1 w of energy you should be able to lift weight of 10 kg by 1 centimeter at 1 second,
or 1 kg by 1 cm 10 times per second, or 250 grams at 1 cm 40 times per second!
But generally speaking, in order to achieve this you need a) - much bigger magnets, b) - much smaller travel of the coil.
According to my calculations the magnet ( the source of the energy) should have the pull of about 400 kg, and the travel about
.5 cm. With your setup this doesn't appear to be practical since magnets will be fighting each other (IMHO).

Hi telcom,

thanks for your interest and test information.

I have a new (stronger magnet) model that I have tested. I noticed that as I drop the current the pull grams per watts is not linear.

Example:

My new model pulls 520g for 1.2 watts input.  However, if I drop the current it can pull 200g with .3 watts input.

Hello gotoluc, thanks for continuing your experiments 

Very interesting to know it is not linear

When you say: "pulls 520g for 1.2 watts input.  However, if I drop the current it can pull 200g with .3 watts input", it is just ratio of force against electrical power; could tel us in how many th of second it lifts them in each case?

Cheer.

Hi Luc,
this is a big step in the right direction.
If it takes 1 second, than the mechanical equivalent of .3 w X sec (.3 joyles) equals
3 kG x cm, and the efficiency is still below 10 %.
Perhaps you may add few more magnets, or increase number of strokes per second or both?
