That it gives you a scope shot without being connected?

It is connected

Is the motor running?

Yes,it is running-thought the frequency and trace on the scope would tell you that.

and why is there that non used piece between the battery and motor bearing stand?

That is the relay timer circuit for the cap dump system-yet to be installed. There is a generating coil to go on top of the rotor,and this will fill caps,and then dump that stored energy back into the run battery.Remember-a well built pulse motor will not draw more power when a load is placed on it,and so any energy generated by the rotor ,comes at no extra cost.

I also assume that you are running with a center tapped drive coil with the center tap connected to the center connection of the series batteries,, and maybe your magnet pole orientation is rotated 90 degrees.

No,the HV MOT coil is split into two coil's,where one half is the trigger coil,and the other half is the drive coil.

And while I'm at it,, maybe your truck needs an oil change?  Tires rotated,, man that would be a lot of wheel nuts if ALL of them heeded it.

No-dont drive trucks anymore 

I like the way it looks like a house with a chimney

The !famous! H wave lol.

Only running at 1440 RPM, need to rework the pulleys, but anyway, first run

Hi Carroll

I'll throw my guesses in here also.  I believe you are running your motor in attraction mode.

The motor is being run in attraction and repulsion mode,as the magnetic field is alternating.
I have two large crescent shaped magnets from a DC motor glued to the rotor. This means that while the coil is pushing one away,it is also pulling the other toward it.

You are firing the coil as the magnet approaches for a pretty short pulse.  That is the narrow pulse.

The scope trace gives us quite a bit of information. The scope probe is across the collector/emitter junction. The narrow pulse you see is the inductive kickback pulse,and the large hump after that,is generated current from the drive coil,that is also charging the charge battery.
The scope trace tells us that
1-the battery being charged has a very low impedance (or internal resistance),and is quite healthy,as the inductive kickback spike is being clamped quite well at near the series voltage of the run and charge batteries. If the charge battery was badly sulphated,then both the inductive kickback spike,and hump after that,would show a much higher voltage value--remember,the V/max on the scope is showing the series voltage of both batteries,as they are connected in series.
2-Most of the energy being sent to the charge battery(in this case),is not from the inductive kickback,but from the generated power of the passing magnet over the coil-->the large hump after the small spike
3-the trace also tells us we are running very close to a 50% duty cycle.

I also think you have the magnet set on edge so that as one pole approaches the coil when the magnet passes the middle of the coil the other pole will be leaving the coil.

This is mostly correct,but where as i have two  magnets set in an alternating pattern,but the results are the same.

Very nice build!

Thank you,but she is not finished yet.
Still have a generator coil to go on top,and the cap dump system to finish

So,some quick power calculations show that i am sending 81% of the P/in to the charge battery.
This means that i only have to be able to generate 19% of the input power,and send it back to the run battery,with my (to come) cap dump system.
Once we do that,we have a self runner-right  . Well as small as that 19% sounds,having tried this before,i know it is a very big ask. There is also the fact that lead acid and AGM batteries,only have about an 80% charge efficiency,where you would need to send 100 amp hours to the battery,to get only 80 amp hours out of it,as there is about a 20% loss in charging these batteries. So we are actually looking for around another 39% of the input power-just to gain unity -but who knows how that will change,having the small inductive spike in there as well.

Hi Ron
Seems to run quite smooth--nice build.
What are the two meters showing?

Beautiful build Brad. I would say coil placement to answer your question


Ron

Thanks Ron.
I still have the cap dump system to finish,and the gen coil to be placed on top of the rotor.

magnet answer in reply to Carroll.
