Keppe Motor simular to Newman-Bedini combination

Excellent craftsmanship and test report Greg

Do I understand this correctly!... the power consumed is 40ma from the 12.46vac side of the step down transformer and the motor turns at 960 RPM with load?

Could you do a no load test to see what the ma draw and RPM are.

Thanks for sharing

Hi Luc,

Just did that now.  It goes 1359 RPM and 12.93 VAC @ 19.83 mA input to the bridge and cap ! !

Peace,

Thanks Greg for doing this test.

That's a good RPM for the ma draw using a low voltage

Looking forward to the Torque tests.

On the previous test I just backed the braking magnet as far as it would go.  I did the test again but completely removed the braking magnet and the RPM peaked out at 1426 RPM.  The current didn't really budge ... down by only.05 mA.

Hey Luc,

Check this out.  I took a look at my cap voltage only to find that it's sitting at 13.89VDC while the motor is running under load. So I started cranking the time scale down and saw what I think is going on with these pulsed motors.  I have never thought to crank it down to the nanosecond scale before which is why I never saw this stuff.

I have included three scope shots of the capacitor terminals:

This first capture shows the motor running and top of cap at a 500usec/div scale ... nothing spectacular so far.

The next capture shows another somewhat familiar and expected picture of the coil's signature at 50usec/div

But at the 10nanosecond scale you really see something incredible.  If you look at the areas under the trace you can see an appreciable amount of charging ABOVE the 13.89VDC average voltage.  In fact the scope is says +29VDC (lower right).  This appears to be a self-charging affect.  This is happening near Gigaherts frequencies and might be evidence of ZPE's contribution, scalar?
