Hi Vineet_kiran,

Just from doing some simple tests the thinner the magnets, the less friction and actuation distant the shield has to move.

Attached is a picture of an alternative idea of using a sliding switch with shields that are lifted by the ramps when the magnet hits it. The goal is to temporarily lock the open state so it isn't coupled with the driving magnet.

A hair trigger snap action toggle switch may also be tried but adds complications with increased complexity and wear.

This design may still stick on the end cycle between the switch but may inspire some new ideas.

My 3D printer isn't so big, so I must use smaller magnets. A coulpe of those small round ones in my "magnet picture".
The fall is not more than 50mm.
I also think the cam will result in great friction and inaccurate lifting process. I will make a try. If I cant continue due to many obstacles I have to think new. I wont spend weeks to complete this experiment.

I already know the outcome if the mechanical is a success (It will never be over unity - even without friction), but I build it for educational purpose only.

Mr.Vidar,


Please don't spoil your 3D printer.  Here is a simple method to verify it. Please see the attachment.

I am attaching two drawings or interpretations of your device.
Please let me know if I have understood your set up correctly.

It is exactly right.  You have to move the shield completely inbetween the magnets to get maximum repulsion.   But it (part of the shield )has to be on the surface of fixed, strong, lengthy magnet.  If you try to take the shield out of strong magnet it experiences dragging force.

Your equations are wrong.  The energy loss for the shield is the (W1 + the shield weight) * H1.  The energy gain for the pendulum depends on the dimensions of W3, W2 and the pendulum arm and the weight of each.  It is not H2 * (W2 +  3*W3).

Very nice imagination.  But how will you hold the shield?  Shield will be experiencing attractive force from the magnet (left or right) and if you try to contain the shield within a box or channel, it experiences tremendous frictional force while moving up.  That is the reason why I thought of moving the shield on the surface of magnet itself,  using a ball so that friction will be less due to  point contact even under tremendous attraction between shield and magnet.
