Is this the first selfrunning overunity motor w/o batteries ? Mike?s motor

Can we get back to the window motor now?

Have not seen this posted.

This is a better drawn circuit diagram version of the Mike motor modification
thanks to user EMdevices.

See the attached picture.

Many thanks to EMdevices.

Not exactly the way was posted: 1 has no connection to +12V, nor GND. In this picture is more a symbol.

However, this symbol (1) & 2 make together a good replacement for reed switch. Or the other way around...

However, I tried lately to play with SSG & apply Mike's principle with 3-rd coil. I found the hard way (by building) another mechanical fixture that HDD berings are much beter than regular ones (duh!). I couldn't believe my eyes the difference. the speed was roughly 1/3 and I could literaly hear the waste of energy.
So lesson 1 (at least for me), excelent mechanical setup is a must.

Hi Dave,
can?t you at least tell us,
if the spikes in your scopeshots are positive or negative,
if you don?t want to share them here ?

I really must know, if Mike inverted his scope shots accidently.

Many thanks.

Hi Barbosi,

yes, the 1 and 2 parts are not exactly the things Mike
used, as he used a Hall ICwith an open collector transistor to
switch the internal LED of the SolidState Relay.
This way the SS Relay was switched on and off.

But you are right.
Part 2 in EMdevices drawing could
probably substituted by just a reed switch positioned
at the right distance around the magnets and part 1 would
not be needed.
Then the reed switch would just close for a few miliseconds
and open up again, when the magnet has passed by.

Too bad, noboy yet has posted scopeshots.
It would be okay to post scopeshots also, if you
drive your motor from a power supply.
The most important scopeshot now needed is the
scopeshot of the voltage at coil 2 and directly at the capacitor
during operation, when then transistors are switching.

Also the charging current at the cap would be great
to have as the voltage on a shunt there.

By the way, by looking at the transistors one user told me,
that the transistors Mike used in his videos are probaby
not the types MSPxxxxx as these are much smaller...
so Mike probably used different transistors.

Stefan,

I dont know where Mike took the readings.  If they are across the cap then they must be right because the spikes must be positive to charge the cap and in any case would have come through the bridge so...

If he read it across the coil, then they must be negative because they come from back emf of the coil as the field collapses back upon the coil after the transistor turns off then in my opinion it was inverted.

Perhaps he was reading two channels at once and needed common ground and used one channel back to front and forgot to invert it.

Are you happy now?
