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

For those looking for the Crouzet 84131100 10A relay Mike ended up using, but are having troubles finding it due to its obsolescence, it looks like the replacement is the 84134100.

It doesn't look like anyone stocks this part though, so I checked the 25A version, the 84134110, and there seems to be plenty of stock.

See http://www.mectronic.com/scripts/mfgpartlist.asp?partno=84134110&mfgid=5804&mfgname=Crouzet&mfg=Crouzet

Aside from being a 25A instead of a 10A, the 84134110 looks to be the same part, and should work well.

It looks like Mike received the "touch safe" version of the SSR, so conceiveably, there could be watch batteries hidden under this "touch safe" cover. See the photos of his new white Crouzet relay.

Not saying there are, just a possibility.

Just a note that may already have been done.

The induction of the main coil  when the feild colapses back into the coil is feed through the NPN transistor as a diode and the bias resistor. This is the main diferance in the original design. The induction timing due to this is were coil three and the switch come into play.
It is also the reason the NPN burnt out.

Hope this helps folks.

Actually, I thought Mike said that the Hall and the PNP died, but it doesn't much matter. I have looked, and there are up to 600V spikes across both the NPN, and PNP transistors, so it is no wonder they may blow.

btw, I have tried the MJL1302A, and MJL3281A transistors as mentioned by John in one of his posts. These are generally used as audio outputs, and they are overkill here, but they seem to work the best so far in my model.

The scope shots:

Trigger, Drive, D2, Generator.

They aren't a perfect match, but close.

All except D2 are differential measurements, with V+ on high side, and V- on low side. D2 is referenced to GND, and is taken off the top of "Rscope".

S1 is not being triggered in these shots as V2 = 0V.

Great work Darren.  It is incredible how well the scope shots simulate what is being observed in reality.  Your model must be pretty good.

I would like to see what happens when you trigger s1.  I'll be interested to see what it does to the D2 scope simulation. (specifically if the "spike" becomes more distinct)


I would also like to see what happens if the trigger winding is set 180 degrees out of phase with the main winding. (because this would be an easy mistake to make)

Maybe this is the actual relay shown in Mikes video...
