Mostly Permanent Magnet Motor with minimal Input Power

[Jimboot]

Hi Jimboot,
well done.

What is the weight of your coil and the power input ( voltage x current)

Many thanks.

P.S. Maybe you can also try it on a charged capacitor ?

Do you still have more magnets that you can use to put on the stator side ?


@gotoluc:

Yes, I meat 12 mm = 1.2 cm
so you need to do at least 10 times better than now.

Hi Stefan I haven't weighed the coil yet but height is 9" 225mm. I've tried a couple of fishing sinkers on it as well. I'll weigh it all tonight.

I just told you in my previous post even showed it in two video's so which part did you not get?

When the magnets are placed NORTH-SOUTH NORTH SOUTH there is no induction because the core is exactly in the middle which is the DEAD ZONE.
This translates into NORTH-CORE-SOUTH where core is in the dead zone.

When the magnets are placed NORTH SOUTH SOUTH NORTH there is induction because there are many field lines cutting the coil and that's what it is all about here the number of field lines cutting the coil.

Yes, but you had a bucking coil, which normaly should not induce any current, cause it is canceling out the induction voltage due to the 180 degrees out of phase series circuit.
But it surely depends how big these bucking coils are and which part of the coil gets how many field lines to cut. so it depends on the location inside the core and where all the fieldlines
are located and what part of the bucking coil gets how many fieldlines to cut , so the difference voltage of each part can be different.

Just then please show the movement of your bucking coil inside the core being powered by a cap
when it generates no induction voltage due to the movement.
Many thanks.

@microcontroller

I thought you were working on it right now,
so I did not realize, that these tests were from 2005.....

The forum will soon be updated with the new PortaMX version
that will fix a few bugs and I also need to move to a new hoster,
but in this moment I have a lot of other work to do, so
I need to prepare this when I have again enough time
to work on this fully for a few days in a row as this is not an  easy
move with all the huge database and huge file archive.


Regards, Stefan.

Hi everyone,

I have internet access again.

I was thinking that maybe we are going in the wrong direction on trying to find the efficiency of this effect by short burst of energy to the coil to move a weight at a certain height.

How about instead we calculate Watts used to hold a weight continuously at a certain height.

Since Induction is present the coil may not be able to lift fast enough to reach its true potential, that maybe why it's staying around 8% efficiency. So lets explore how many Watts it takes to push a weight to a certain distance and hold it there.

If we look at Jimboot new idea and video demo we will realize that a weight could be potentially pushed up very high without adding any extra energy.

Can someone please post the formula so we can calculate its efficiency this way instead.

Thanks for all sharing and great job Jinboot

No worries mate here's the latest http://www.youtube.com/watch?v=f2yhfyjLqBs wondering if the way it sails past the middle mags is significant

Great idea mate.

Before seeing your new video I was going to post that I feel we are probably calculating the efficiency the wrong way but after seeing what you have now figured out I really feel we need to come up with a new efficiency calculation formula.

Thanks for sharing your improvements
