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

Before running a sim on Peter's new circuit, I'd like to take a closer look at D2 and its pulse.

First shot below you see the D2 shot, probably my best so far.

2nd shot, you see 4 plots together: the D2 again, the switch state of S1, the voltage acrss D2 to indicate when it can conduct, and the current through D2 to see if it's doing any real work.

The voltage pulse looks somewhat impressive, and even the ~800mA spike may seem impressive at first, but look at the 3rd shot below.

3rd shot, you see D2 current again, plot along with the D2 shot to give some perspective. The current spike is ~800mA, but its duration is too short to be of any real use.

Well, anyway that's what the model is producing at the moment.

Regards,
Darren

My scope shots are getting a bit closer to Mike's (without the apparent OU dip), but the spikes on mine always go downwards and Mike's went up.

Sam,

I'm not sure if you've inverted your scope shot, but Mike's in your superimposed shot is inverted as he posted it.

I would encourage you to not invert your channel, nor the scope leads when doing your measurements. Mike's scope shots are inverted, simple as that.

Mike's spikes go down too. Look at my scope shots. When the S1 timing is right, there will be a positive/negative spike, but it is still mostly negative. When S1 is not triggered, the spikes are only negative.

Could you please also post your L1, L2, and L3 shots? Thanks.

Hi Darren
looks good, have you considered the hall trigger switch time, the magnet in the film looks very wide between 5mm-8mm if you worked the diameter of the wheel out, then the rpm it should give and approximate on time.

Could you please also post your L1, L2, and L3 shots? Thanks.

These are my Coil shots. I have also added a D2 shot with R2 connected to Positive.

Hi Sam
nice to see another sim going.

Darren my Inductance meter arrived this morning.
Here are my windings

I wound quad-filiar
3 stands of 28AWG
1 strang of 30AWG

Trig strand = 40 Ohms at 13.14mH 30AWG
Main 2 * 28AWG in series = 50.2 Ohms at 49.6 mH
Gen = 25 Ohms 13.07 mH
These measurements were taken with the shaft in place but no rotor fitted.

Looks like winding the Main as 2 strands and putting in series has had quiet an effect on the inductance.
