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

Dingus,

Was the core the same material in both models?

Can you do the first one again with a ferrous core?  If you are really feeling ambitious, maybe both of them with a ferrous core?

Sam,
What circuit are you working with?  (I'm losing track of what everyone is doing!)
Are you using Mike's original modification of the Bedini, or some other circuit?

Hi DB

I am definitely using Mike's modified Bedini-Cole circuit except that I still don't have all the exact components. These are my current substitutions:-

Diodes : 1N4004 (Also tried 1N4148)
Transistors : 2N3055(NPN), MJ2955(PNP) also tried MPSA069( NPN) and MPSA56(PNP).
Relay: RSR2ND-A24003
Hall Sensor: 6340 bipolar (also tried 3503 unipolar)
Capacitor: 6 x 10,000uF 50v
Bridge Rect: RBV-602

I have ordered the Crouzet relay from the UK but have been unable to locate the 1N910 diodes anywhere.

I would appreciate any assistance with recommended substitutions or suppliers that will ship to Australia.

Cheers

6x12x150 mm Ceramic #8 magnets
53 mm rotor core

Wow - many thanks Dingus - definite gaps in the flux between the magnets.

Cheers

Sam,

That 1N910 diode is supposed to be a 1N914B diode, but a 1N4148 will work the same.

Out of curiosity, you tried a couple different transistor types. Did it make any difference to either the waveforms or motor performance?

I'll put the 1N4148 diodes back on, as I didn't have the scope when I tried these previously.

I could not detect any change whatsoever with the different transistors. The ones I tried (MPSA06 & MPSA56) were supposed to be alternatives for the MPS8099 & MPS8599 specified in the Bedini-Cole Circuit.
