Begginer advice needed
« on: April 05, 2015, 04:16:09 PM »
Hi

I am using the following circuit for a drive coil on a bendini sg wheel. When the drive coil runs the neon comes on to, unless I adjust the variable resister down close to zero. Can anyone explain this to me please?? The rpm of the wheel is much higher when the variable resister is adjusted with the neon lighting.

Thanks

Nathan

Oh! Yes, I spelt it wrong once and the flipping auto correct now changes the right spelling into the wrong one! Lol

When you have the resistor adjusted properly the transistor is switched on and off cleanly and abruptly by the approaching rotor magnet inducing a voltage in the pickup portion of the coil set to turn it on, and this voltage being "quenched" by the opposing field of the second coil as it turns on which then turns the transistor off. This interrupts the current flowing in the larger "secondary" portion of the coil set which is driving the magnet rotor. . When the current in the coil is interrupted its magnetic field tries to collapse. The collapsing field tries to keep the current flowing, but there's nowhere for it to go since the transistor is off. So the voltage builds up until it reaches the threshold voltage of the neon. The neon then fires and becomes essentially a short. This allows the coil's field to collapse more completely because the circuit back to the battery is complete. When the neon turns off the cycle repeats. When you have the base variable resistor turned to too high a resistance the transistor will not turn completely on, so the coil doesn't charge properly and the motor doesn't run as well. When the motor is running well it is flashing the neon so fast that you don't see the individual flashes and it looks like it's continuously lit. If the neon wasn't there, the transistor could fail because the voltage from the collapsing magnetic field could exceed its max C-E voltage rating. This "inductive collapse spike" can easily reach many hundreds of volts so the neon is kind of a safety valve that protects the transistor. The NE-2 neons typically fire at around 90 volts and shut off at around 50-60 volts or so. When they are off they have a very high resistance, essentially open-circuit. When they are on their resistance is very low, essentially a short-circuit. This is why neon pilot lights for AC equipment have to include a current-limiting resistor, so that no more than a few milliamps will flow when the neon is on. Another interesting thing about neons is that only the negative polarity electrode actually glows. If you see both glowing, you know that you are seeing AC, which is alternately making each electrode negative, at the frequency of the AC current.

TinselKoala.  That is probably the best explanation of that circuit I have ever read.

Good work.

Thank you Tinselkoala. That's very informative. So, I could do with catching that extra energy and feed it back?

You're welcome, and thank you!

To capture or "siphon off" the inductive collapse spike you can connect a fast diode, like UF4007 or BYV26E or similar, with its anode at the Collector of the transistor (junction of coil, transistor and neon) and its cathode to the Positive terminal of an electrolytic capacitor of, say, 22 uF 400V. The negative terminal of the capacitor connects back to the battery negative.  The capacitor will then charge up to the peak voltage value of the inductive collapse spike. You can monitor this voltage with a DMM set to the right voltage range, across the terminals of the capacitor.  Be careful doing this, don't exceed the voltage rating of the capacitor, and also beware because the capacitor can store a lot of energy and release it all at once if you let it. The more capacitance, the slower it will charge but the more energy it will build up. The neon probably won't flash until the voltage on the capacitor starts exceeding the threshold value of the neon.

You could also put another battery in place of the capacitor, and "spike charge" this second battery directly this way.

The only problem with this whole scheme is that all the energy comes from the main "run" battery in the first place. It's not really "extra" energy at all. But normally it is just wasted in heating components or flashing neons, and it may be put to better uses than that by using some kind of "siphon" circuit like I've described above.

You may find this short video of interest. It's part of a longer series of videos developing, testing and describing the "MHOP" better-than-Bedini pulse motor.

@tk

I like your neon circuit pulse idea. Bedini's older motor that had a secondary wheel that would fire a mechanical switch after a
capacitor had taken several hits from "bmef". This is because the back emf pulse may not be what voltage the battery is looking
for in terms of recharge.

Thanks Tinselkoala! Great advice. Great video. What battery's do you recommend? Flooded cell car batteries? Are the small batteries in alarm systems any good, I guess as they are sealed they are gell.

Oh, here's a big one. What about coil shorting. How could that be applied to a vertical bicycle wheel? From the circuits I have seen you need a coil to power the mosets and then a couple of hall sensors, which would need mounting maybe to pick up small magnets on the side of the wheel.

The batteries I'm using are SLA, Sealed Lead Acid, 12 volts 5 A-H capacity. I have six of them, they are originally made for UPS computer power supplies. I imagine that the alarm system batteries are about the same type. I use them for various purposes and frequently discharge them down to 11 volts open circuit. I guess they are three years old, maybe older, and all six are still working quite well.

Most people who work with Bedini charger systems seem to use flooded Lead Acid car battery types, I think.  I don't have the room, and I don't want the evolved hydrogen gas and spillage problems that unsealed batteries cause. Plus those things are dangerous. Your mileage may vary of course. I charge mine with an automatic automotive battery charger, Penske #7061261, which takes them up to about 13.5 v open-circuit and floats them there. It works far better and faster than any Bedini charging system I've tried.

As far as your question about "coil shorting" goes... I'll need more information. Often you will see a diode connected with anode to the negative side of a coil like for example a relay coil, running back to the positive side of the coil with the cathode of the diode. This "shorts" the inductive collapse spike or some would say "recirculates" it in the coil itself. This may be advantageous for some types of pulse motors. I don't  know enough about the particular scheme you are talking about to comment further. If you can show a schematic and give details of the rotor I'll see if I can understand what's going on, or supposed to be going on.

I've got some Hall-effect triggered pulse motor demonstrations in my video collection. Here's a photo of one of them, and a schematic of another one. These use "latching unipolar" HE sensors. Ratiometric sensors could also be used, with an op-amp comparator stage to adjust response.

Cool. At the end of the day, I'm not interested in battery charging. I am after an output which could be more useful, such as powering lights etc etc . I will take a look at your videos in a bit. :)

I have the fast diode and capacitor as stated by tinselkoala. Tge neon goes out for a few seconds whilst the capacator charges but once it reaches 90v it does not seem to discharge. I read a steady 90v across it and the neon starts flashing again. Is this right?

Thanks
