My Motors got me to Tap into Radiant Energy

...Thanks for being such a "Gentleman" with Our Lady!!...

Yes, completely right...SHE does NOT likes Snubbers...Flywheelers nor Chokers...
...

AGREE!
My concern is to be a gentelemen to our electronic first in order to test the secure operation area. It does make no sense if we burn FETs after FETs in blind flight.
i.e.:
Start with snubbers and check what happens on every specific setup.
Start with bulbs in series to load (i.e. car bulbs H4, H7) in order to detect failures prior to burning FETs.

Once we have electronics secure and FETs fitting to the specific application we can get rid of bulbs and snubbers. Ready for takeoff!
Then the appartment is ready in order to invite HER for a private tête-à-tête

Glad you accept the way with micro - current technology. My goal is to negotiate between HW vs. SW effort. While SW is easy to replicate for ALL the HW will request effort, cost and more expertise at every desk.

And yes the user I/F will be added for sure fitting to the application. Nico used a grafic display and a simple pot. It will be suffitient for small frequency areas. For later sophistcation we could use digital knobs. Any CD drive motor can serve as digatal knob by adding a simple opamp.

There you have it folks! You gotta give the lady what she likes! Then she's gonna do wonderful things for you!

You're welcome UFO! My pleasure!

Hi ALL;
my circuit diagram is the first draft.
- I feel the exact type of optos is not essential because the 555 reconditions the signal. But the pullups at in and out (r1...R5) will be tuned for best performance.
- Same the resistor (R6) between 555 and bases of transistors along 555 bein CMOS or NMOS.
- Same the gate resistors (R7..R10).
Those parameters can be tuned at real circuit only.

I will supply the micro via a socket charger while using another one for 555s. So we are completely independent of the presence, value and spikes of load voltage.
Everybody owns some socket chargers laying around and this is a simple chance to reuse them. You might need to add an additional voltage regulator. The LM317 is a good choice but needs additional resistors and many of you have problems with it. I prefer 7805 or 7812 fixed regulators. But please note the heat dissipation is minor to the LM317 - but still far suffitient at this specific application. We require no extra heat sink.

Absolutely Agree with You John!

Hello My Dear Friend,

Yes, absolutely agree with you here...We have to protect the "Tronics"...
I love the Arduino Microprocessor as We are able to program it very accurate and seen it on our LCD Displays...awesome!
Your concept with the Opto's is also great, they create a Space Barrier between low voltage signals and the Monster Load we are Pulsing at the other side...
Using the 555 to enhance the Gate Drive Signals is a very smart and inexpensive way to achieve great results.

Yes, a PC Display Interface...plus a Manual Pot would be great and enough for our testings for now...

Let's wait for Nico...(I believe He should be busy having a great time...making excellent BBQ Meet and having some nice Argentinian Red Cabernet Sauvignon ...)...Just kidding Nico!!


Warm Regards John,

Got contact to Nico -> discussing going on!

Hello fellow builders

UFOPolitics, this is looking amazing. Much respect to your experience, ingenuity and patience ;+}

I am on page 9 of this thread, fantastic reading but i just had to stop in order to express my amazement and thanks

Amazing work !!!


All the best,

QV.

Hello builders

I think i know enough now to replicate the circuit in it's simplest version, i already have a good PWM.

I am having trouble getting hold of an NET576 or NET577, they only seem to be stocked in the USA and they say they cannot deliver to the UK due to export restrictions !!!

An alternative is an HFA16PB but it's £35 here in the UK !!!

It's only £8 from China but delivery is a few weeks

I am only on page 15 of the thread so i'll keep reading, anyone know of an alternative diode that is fast enough, any UK builders here ?


All the best,

QV.

[qvision]

This is my PWM :

Power Pulse Modulator - OCX


Cheers.

@ qvision
Just for (starting) on the small motors or neon experiments, any fet out of an old power supply or the like, or just one of the relative rating will work. I have used the IRF840 to the IRF540 for small setups to get my feet wet. Good luck and keep doing what you are doing. As you go, show us what you are up to and if any problems, let us know. All the answers are in the text but in pieces.

Thanks prochiro

Thanks very much prochiro, i can tsop being so anal about it now ;+}


All the best,

Check the UF505...

Hello QVision,

Please check the UF505...That is exactly same thing as NTE576...

@UFO
The bearings that came with motor are rated for 12000 RPM and good static and dynamic levels. If we just set in a screw tightener as you suggested, with (no) wear in our bearing ports, do you think that is enough???

Hello Prochiro,

Yes, but they are Chinese...basically the rear one...I got the rear housing messed up...because of that, as also the play they come from factory...
I got a Japanese that would go 18,900...

That the locking bolt would be the final and best solution?...
Absolutely NOT!...It is just a Patch...

Now, those Housings have space to drill four holes/thread them for four locking bolts...I mean...what else could we do?...that would not become a big time project beyond the possibilities of many here making this replications?
If you have a better/easier/simple and cheaper idea in mind...please shut me with it, am ready... ...

By the way...do you have one or two Imperial Kits?
You should be waiting for epoxy to dry to run your motor right?

@UFO thanks for the advice

I have ordered IRFP460 FETs.
I have this PWM :

Power Pulse Modulator - OCX

I cannot get UF505 or NTE576/577 in the UK and cannot find anything similar on ebay or amazon.

Any UK builders here and what diodes are you using ?


All the best,

[qvision]

Can someone in the US post me a couple of these diodes please ?

I will pay you via PayPal before you send.

Having a real hard time finding anything comparable, apart from this :

DIODE, ULTRAFAST, 16A, 1200V, Part # VS-HFA16PB120PBF | eBay

But it's £35 !


Cheers,

DC.

[qvision]

I've ordered these :

HFA16PB120 Ultrafast Soft Recovery Diode, 16A IC | eBay

I will just have to be patient

All the best,
