Mostly Permanent Magnet Motor with minimal Input Power

[hallo]

microcontroller,
your crankshaft design looks great !
Please post also any updates when you get it to run with all the electronics connected.

many thanks !

P.S: Please explain more your recent 2 videos with the coils.
As I am not at home and am currently in a public library I could only see it without audio.

But more explanations how the coil configurations are killing the induction would be great !

[hallo]

Here is the formular for the height to be 100 % efficient.

For overunity you must just have a higher height than this value.


height in meters = 0.5 x C in Farads x voltage^2   /   (mass in kg x 9.81 )

For our US based users they are probably more use to inches,
so we can convert this formular to height in inches and the capacity in uF :

height in inches = 0.5 x C in uF x voltage^2  x 39.06 x 0.000001 /  ( mass in kg x 9.81 )

[hallo]

Okay, here the formular for also the mass in Gramms, the capacitance in MikroFarads (uF) and the height in Millimeters or in inches:


height in inches = 0.5 x C in uF x voltage^2  x 39.06 x 0.000001 /  ( mass in Gramms x 9.81 x 0.001 )

height in Millimeters = 0.5 x C in uF x voltage^2  x 100 x 0.000001 /  ( mass in Gramms x 9.81 x 0.001 )

Stefan,


I have mounted my experiment vertically and added some weight to the coil.


Can you do the math on this please?


Steady state the coil is 12 volts at 1 amp


The weight of the coil and added weight is 358 grams


The height traveled is 47.5mm


The time is 98.75 mS


I have a N.O. micro switch which shuts the power off at the top of the travel


A couple of extra pulses here until the main switch is turned off


The time is in between the T1 and T2 markers


Thanks


Ron

According to my calculation you gained 0.17J in potential energy and used 1.185J electrically so 6.9% efficiency in that case. But this test alone is not really good on its own due to joule heating and wasted inductive energy.
