Reviewing Pulse Motor Circuit Ideas and Theory

[ltseung888]

ltseung888:
can't believe I missed your post. sorry about that.

I think most would agree that the waveform analysis with a scope would be ideal for perfecting the rotational moment for the correct timing of the firing of the pulse in those cases.

I regard the negative energy (negative voltage x positive current) as Lead-out energy...  The goal is to maximize it.

In the pulse motor competition, it may be a good idea to examine the waveform.

What I forgot to mention was: Assuming you managed to frequently interrupt the current flow (eg. the one induced by your Bedini wheel) and this results in a dense cummulation of voltage changes - then you still have no gain. What you need to do, is, you need to push this trough a low inductance 1:1 transformer and only then the frequent voltage changes are turned into frequent magnetic field strength changes, and only they have this feature by which energy increases with frequency. That may be a ferrite ring core with few turns.

Speaking of which, a joule thief could be used as a interruptor trigger. They normally run somewhere between 15 and 100 kHz. Instead of your LED you would then trigger a GTO, which is the solid state equivalent of a relay. The GTO would then interrupt the current, as described earlier. Using Mosfets and Transistors is always rather lossy  IMHO. However, as a low/cheap tech version you may use a simple bell-ringing interruptor: As the current flows trough an additional coil, it causes a magnetic field that pushes a contact that interrupts the cirquit, hence no more flow, hence no more magnet, the contact is reestablished and the current starts flowing again.... Really low tech.

Tesla coil is about high voltage. Not sure if it is what you need here.
But you're right, he used the term "Radiant Energy" in both, the magnifying transmitter and the collector for radiant energy patents, if I recall correctly.

hi dieter, and others

Assuming you managed to frequently interrupt the current flow (eg. the one induced by your Bedini wheel) and this results in a dense cummulation of voltage changes - then you still have no gain. What you need to do, is, you need to push this trough a low inductance 1:1 transformer and only then the frequent voltage changes are turned into frequent magnetic field strength changes, and only they have this feature by which energy increases with frequency. That may be a ferrite ring core with few turns.

The Bedini is interrupted by the magnets passing the trigger coil which then affects the TIP3055, or whatever transistor you're using, to fire the main coil winding.

Tesla coil is about high voltage. Not sure if it is what you need here.

Yes, this is where this is going.

Either the air coil type or a carbonyl iron core which does operate at high frequencies may be satisfactory with a PLL interrupted circuit like TinselKoala mentioned, and others use in their high frequency tesla coils, the SSTC PLL circuits. Definitely experimentation is in order here because most who have posted about Tesla coils of any type are only pointing out what their coil can do in relation to the discharges, not really measuring the energy from the high frequency pulsing of the coil itself at the field collapse interval,  and this what I am interested in.

TinselKoala on the other hand in this vid on Youtube does show some oscilloscope tracings:

I can't make heads or tails of these, except to note the frequencies which are visible. I couldn't tell how high the voltage spikes were. Can you elaborate on those tracings TinselKoala?

Of course, anyone here who has a Tesla coil and an oscilloscope with the right frequency capabilities can already possibly do this. I appeal to any of our other members to look into this for us and post it, either in Youtube format or maybe some still pictures for us here. According to the Tesla data I have read, high frequencies with low on times (less than 100 microseconds) of the energy pulse seem to be safest, according to Peter Lindemann in "The Free Energy Secrets of Cold Electricity." Also, the energy should first be stored in high capacitance capacitors that are discharged quickly.

Again, experimentation is important, but time and money intensive. I definitely do not want to reinvent the wheel. That is wasteful in more than one ways.

Also anyone working at a decent sized research university, especially in the Physics or Electrical Engineering department could be very contributory here. Plus you all should have some great experimental tools at your disposal which most of us could not afford directly.

thanks for everyone's input and help. for those I have not directly replied to at the moment, please be patient. Sometimes I can't get back too quickly, but I am also seeing and reviewing other peoples research and circuit designs to become more educated here. electronics is not my first love.

With further thought and not really trying to build the Tesla coil to generate sparks, but build the secondary coil itself and use it as my Mains coil ala the Bedini style circuit.

Can I merely add a 555 timer circuit (set up properly) to trigger the NPN transistor to the medium to high frequency range as delineated in the posted frequency bands so that my Tesla coil secondary can respond as the main coil in the Bedini type circuit?

Next question, can this be kept in the lower voltage dc range, like 12-24volts?

We can work on the correct programming for the timer circuit soon, or if anyone already knows, please share.

thanks a bunch from everyone who has participated so far.

Here is at least 1 circuit I saw posted that may be a start point with an explanation.

http://www.electroschematics.com/4843/1-hz-pulse-generator/

re is a 1Hz pulse/frequency generator using the popular timer IC 555 which is wired as an Astable Multivibrator. The output pulses can be indicated visually by the LED. An Astable Multivibrator, often called a free-running Multivibrator, is a rectangular-wave generating circuit. Unlike the Monostable Multivibrator, this circuit does not require any external trigger to change the state of the output, hence the name free-running. This circuit can be used in applications that require clock pulses.

555 1Hz pulse generator circuit

555 datasheet
An Astable Multivibrator can be produced by adding resistors and a capacitor to the basic timer IC 555.The timing during which the output is either high or low is determined by the externally connected two resistors and a capacitor.

Clock: A clock is simply a square wave i.e. alternate high & low states. Each alternate high-low forms a clock cycle with a specific frequency & duty cycle. Frequency is the number of cycles completed in 1 sec & duty cycle is the ratio of the time period of high state to the time period of the low state.



We can set the 555 to work at the desired frequency by selecting the right combination of resistances & capacitance.

Frequency = 1.44 / {(R1 + 2R2) * C1}

Also, 555 can produce waves with duty cycle else than the 50 % cycle.

Duty Cycle = (R1 + R2) * 100/ (R1 + 2R2)
where duty cycle = Ratio of time period when the output is 1 to the time period when the output is 0.



Circuit Working

Capacitor C1 begins charging toward VCC through resistances R1 and R2 (VR). Because of this, the charging time constant is (R1 + R2( VR)) C. Eventually, the threshold voltage exceeds +2/3 VCC, the comparator 1 has a high output and triggers the flip-flop so that its Q is high and the timer output is low. With Q high, the discharge transistor saturates and pin 7 grounds so that the capacitor C1 discharges through resistance R2 (VR) with a discharging time constant R2 C.

With the discharging of capacitor, trigger voltage at inverting input of comparator 2 decreases. When it drops below 1/3VCC, the output of comparator 2 goes high and this reset the flip-flop so that the timer output is high. This proves the auto-transition in output from low to high and then to low. Thus the cycle repeats.

feel free to mix and match for us all.
