Mostly Permanent Magnet Motor with minimal Input Power

Thanks Tom,

I now see how your system works.

So you think all these bearings and gears are more efficient then a crankshaft!... I would not of think so but since you built it I'll take your word on it.

Very interesting and thanks for sharing

Hi Luc,


Here is another clever crankshaftless design

Hi Luc,
well done new video.

In your video 5 about it,
you would need to lift this coil up 1.2 cm to get to 100 % efficiency.
All over 1.2 cm lift would be overunity at this cap size and charged voltage.

But you only lifted it maybe 1 mm ? So you need to get it lifted 10 times better,
which could be probably done by just using many more and much stronger magnets...

Magnet motors and things have to be build at least 10 times more bigger than this to get into the
overunity mode. If you build it too small, you will never have the chance to get it to overunity !

Here always the truth it: Size matters and bigger is better !

Luc,


I had to do a quick test on your neat idea. 


The coil is 27mm wide with about 730 turns of #25 wire for 12 ohms. Running on 12 volts is about 12 watts.


The magnets are 1/2 x 1 1/2 inches (12 x 38mm) the rod is 3 inches of 1 1/2 inch CR steel (76 x 35mm)


For the pull test I am starting with the coil to the left and pulling to the right.


With single magnets the initial pull is .75 KG's finishing at 1.02 kG's


With two magnets each end the pull is 1.2 kG's and 1.4 kG's


This is quite a contrast with a solenoid where the pull is very slight at the start and ramps up to maximum only at the end of the pull in.


On the use of a crankshaft: I would suggest timing the pulse to only cover say 80% of the stroke and so when the crank pin is immediately in front of or 180 at the other end of the stroke there is no pulse input. A small flywheel would carry the machine through the dead band.

Hello Luc i did some experiments along these lines in the late 2005.
It can be as easy as sticking magnets to a modified transformer see below.
These are used is SMPS for noise suppression.

The coil form usually has 4 segments so i cut it into half leaving two segments only, and then it can move over the core due to the created free space.

The coil form you see in the picture is specifically wound the first segment is wound clockwise while the second segment is wound counter clockwise, and i think you can guess what the field looks like when it is energized on a DC current 

Hi microcontroller,
interesting coil modification, so you have the coil built like a bucking coil ?

So how are your permanent magnets then polarized outside of the core ?
Just north to south ?
Would be interesting to see your coil current on a scope, if it will kill
out all the induction from the movement as the 2 coil parts are 180 degrees out of phase
so the induction from the movement will cancel all out ?

@ gotoluc

I just recently got to watch a good chunk of your videos.  I'm incredibly late, having avoided research for a few years; but Great job with all the work and videos!
That's pretty much it ATM, lol.  Just wanted to say good work!

Thanks
