Bedini type pulse motor measured overunity !

Have a look at
user ktservicecop?s latest videos:

He needs only about 0.7 Watts input
and gets over 3 Watts out at light bulbs powered by charged up capacitors
from BackEMF and his alternator.

Looks very nice.
Hopefully the input amps are not measured wrongly with his
digital amp meter due to the pulsing.
But he surely can have the Newman effect on the relay points
making it need less input power due to the arcing at the relay contacts.

I am looking for a way to correctly measure what the input is for the pulse motor. This motor will run for a VERY long time on the 12v battery. I ran it for 4 days straight, until one of the magnets flew off  lol, and the voltage only dropped from 12.20 to 12.05v. I know someone on this sight can help me measure the input watts correctly. I DO NOT want to give misleading information. I am going to post a video today and show exactly how this is wired up. People have been asking for the schematics and I keep telling them to start with a pulse motor. You can see how one is built and can buy the glass reed switches from simplemotors.com. I look forward to a response.

P.S. I didn't know a thing about electronics 4 months ago. As a hobby I make classic furniture and can build anything I set my mind on. Please bear with my ignorance while we get through this.

Hello Todd,

Keep squeezing, you can get more Power out of your system. (Tunning, Tolerance, Precision, Qulity)

Here's an example of a 48 Volt Stator at 140 rpm - stator is wound with #15 AWG wire, 9 coils (105 turns); cast in a mixture of vinyl ester and ATH (Aluminum trihydroxide).  The stator is 1/2 inch thick and 15.5 inches in diameter.

Hi Todd,

I?m in a run. The issue is too complex for a short reply but basically you may, for a start, wish to filter (integrate would be the correct term) the current spikes as you already did for the output. Buy several resistors (5W should do it) of about 50-300ohm and also and a large capacitor rated 12V min. Place the ammeter in between battery and resistor. Output from resistor and from the other pole of the battery goes both on the capacitor, which is in parallel with the motor. You?ll need a second DMM to measure voltage on the capacitor (This is a must; can?t work with just one DMM. But a cheap DMM model will suffice for voltage measurement. An analog one /an old one with needle/ is even better). For best results, the capacitor is recommended to be as large as possible (the larger, the better; it?s only depending on the money you?re willing to spend; one of several hundreds thousands microfarads is not very expensive and it should do it; electrolytic is acceptable and quite cheap). For minimizing the errors, you have to try several combinations in identifying the largest resistor that keeps your motor running. Eventually a rheostat instead of fixed resistor(s) may be of great help. In the same time, the voltage on capacitor shall keep into reasonable fluctuations. (If the capacitor is large enough, you shall apparently see no fluctuations at all on DMM voltage readings). It is possible that you?ll find a need to increase the initial voltage (i.e. to use two series 12v batteries series connected). If you?ll find this is the case, do it. The only concerns are the heat dissipated on the resistor and the capacitor maximum rated voltage. Power in = current (through resistor) X voltage (on capacitor). Notice that the method is just an approximation but it is not bad and the alternative would require an oscilloscope and some knowledge that may take quite a long time to be grasped.

Hope it helps,
Tinu

Hi Todd,
many thanks for coming over here.

Yes, one can run such a pulse motor
on attraction or repellation.
Depends how you configure your magnet poles
and your coil polarity during the firing pulse.
With more coils surely you will have more torque
and thus more output power.

But if your input current reading is right,
and really so low
you should be able to selfrun the motor
already.

Just use the 10 Volts x about 200 mA output coil-cap combination to loop it back to the input and it should already selfrun !
Good luck !
Regards, Stefan.
