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

Hi Lindsay, thanks.

Perhaps the TPU does take advantage of these bemf spikes and the output is perpetuated by a spike cascade back and forth from control to collector and back again in resonance?

Maybe a solid-state version of one of the Bedini motors is not too far off from or dissimilar to the TPU.

With good rotor balancing, flywheel effect, and bearing tweaking, it should be possible to approach 95% efficiency or so. I think perhaps one other area of investigation to improve the overall efficiency, would be to use much heavier gauge wire for the windings.

Production electric motors do this every day.  Most high efficiency production motors are at least 93% efficient.  Larger horsepowers are even higher.  There is nothing unusual about 95% efficiency in production electric motors.

I have several small motors at home and at my office that have run for 3 or 4 years on a single AA battery.  They have 3 concentric output shafts running at different speeds - one running at 1 rev/min, one at 1 rev/hour, 1 at 2 rev/day.  They will probably run for several more years on the same battery.  I call them "clocks".

Point is, there is nothing strange about motors that run on milliamps, or even microamps - when they aren't doing any real work.  A motor that is doing no work (other than spinning on its bearings) should draw zero current, other than the copper losses.

DB,

I agree that there is nothing unusual about production motors having 95% efficiencies, and I didn't state that this was unusual.

I would venture to guess that Mike's motor is/was far less efficient, so he is overcoming this low efficiency to power the motor, and still keep the capacitor charge rising.

How many clocks have you seen that run on a precharged capacitor?

AA batteries pack a surprising amount of energy compared to what can be imparted to a large cap from a light spin of the rotor.

No matter how little the load, a motor is doing real work if it is spinning. The less efficient the motor, the more power required to maintain rotation.

It sounds like you would not be satisfied to see a self-running motor such as Mike presented? What if Mike tweaked the efficiency of his motor then implemented a 4th generator coil to power a LED. Wouldn't that impress and or convince you if it was done strictly from capacitor power, and for an indefinate time period? It would impress me.

Hi (lot of positive terms) guys!

For those who might be interested in my
Non-Running-as-Expected-Mike-Modified-Bedini-Cole-Window-Motor :

This thing is slowly but continuously running while powered with 3 cheap 1.5 volts (non refillable batteries). These batts cost me - a couple of months ago - one Euro for a set of 16. Actually, I have to thrown away most of them. 

It drawns about 25 mili amp. The voltmeter is showing less than 4 volts under load.
It shows about 4.3 volts without load (the batts are almost dead).
BTW : this voltage is also slowly but continuously falling... 
The RPM is about 240 (=/=4 revolutions/sec). The Crouzet Relay LED is blinking at the same rate (of course).

-----------------------------------------------------------------------------

Else:  and this is an "half backed idea" (sorry for this half-off-topic-post):

I have just made some quick measurements with my tiny, faster (but no so efficient? (as it needs about 150 mili amp)) SSG3 Bedini motor. It runs with a set of 6 reffilable 1.2 volts batts.

I can charge a 22 000 micro Farad cap at 6 volt in about 2 seconds.
At 10 volts in about 5 seconds.
AT 15 volts in about 13 seconds.
Actually : the cap voltage is slightly increasing (about 2 volts) after I disconnect the wire.
BTW : I can charge a 4700 micro F. cap at more than 100 volts. This means that the output voltage of a SSG device is far more important than a window one.

I was just wondering  whether I could not mofify the circuit to have my SSG3 motor running  "almost" only on a cap (after having it filled by a batt and while hand- operating a switch). This would be the first "hand driven 'selfrunning' motor"! 
This could be dubbed the "oxymoron motor"... Could it not be?

ND,

Nice charging with your SSG3 motor.

Any idea what your SSG3 coil inductance and resistance is?

Of course the inductance of the coils used for the SSG motor are going to be magnitudes higher than that obtained with the air-cored window motor coils. As such, the bemf spikes and charging ability will be greatly enhanced in comparison.
