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

Hi Darren
Yer im desperate for a scope, the mrs cant justify me buying a nice one
but i can

Peter,

At these kind of prices, maybe you can convince the Mrs.

This essentially the same as my Hitachi, but mine is only 20MHz. I paid $940 CA when it was new 

I'm very happy with my Hitachi.

Darren

PS. In fact here is mine....going for a lowly $13 so far

Hi Darren
Ive just put an offer in for a 5022 that MegarMan mentioned they were asking ?139 + ?89 postage and packing, i have put an offer in for ?99.99 as i see from their feedback they have previously acepted it.


PS By balancing the rotor i have got the min voltage to 14.5, and boy was the balance out, i used wooden circles for the rotor, that were cut using a circular hole saw.Still need washers on the end to butt up against the bearings.Not happy with the bearings still quiet stiff, might try a soak in light penertrating oil.

hi every one

i used plastic for center of rotor and a stainless steel sleve my shaft is stainless also this is metalic but not magnetic

main winding is 500 turns of 28 awg or .30mm

generator winding is 400 turns of 28 awg or .30mm

trigger winding is 250 turns of 30 awg  or .254mm

i will give out resistances soon

thanks

@Peter,

I re-wound the coils today and have been playing, but then I got a damn cluster headache which I get now and then and couldn't focus properly, so didn't get much done.  To answer your question, I have only tried with a 12v battery so far.  I do have a variable voltage/current power supply and will see the lowest operating voltage over next few days and post results.

@Darren,

Thanks for the advice regards the transistor, will make some changes over coming days.


Regards,

Dave.

Hi Dave
Thanks, I get headches sometimes which i just cant tolerate light's.

Warren sounds good, will be interesting to see performance.

Also using my circuit diagram, all wired apart from the hall side of the SSR, if i short the SSR out as if its on all the time, the Rotor speeds up and allows me to drop to a lower voltage of about 12 volts to maintain revs, i notice it seems to draw more current tho from the power unit.
If i swap the polarity of the Gen winding, it slows down the rotor and draws more current.
