The problem is persisting Please can you do something about this as it really wastes time hours in fact trying to use these forum Threads

I do not have the same problem with other forums I am registered with

PS
even trying tosend this post I am having problems and some times it double posts because I have to send again

I suffer from the same problem but at late European evening only. I guess it is either data path overload or some database maintenance.

Here is a site you may find interesting. A 160A , 13 to50V DC motor HDrive controller with all the math done.

Robot Power Products - Open Source Motor Control (OSMC)

Nice hints - thanks! I will extract some details out of the schematic.
Unfortunately they provide H bridges. Their protection circuits might kill radiant effects.
Same facts for their decent Arduino shield (MegaMoto) with motror driver.

@ALL: There are a pluraity of chances to build or buy a driver and/or modify it and unfortnately we can not discuss all variants here.
I suggest to disclose a modular schematic everybody can build (based on Lester's suggestion (555 with transistors added). Other solutions may be discussed but unfortunately not in deepest extent (practical reasons).

Coil question...

Greeting all:

I have built and tested an 8 FET motor runner based on JS's modular design. It did smoke a NTE576 .... too much current, so there will be some higher amperage fast switching diodes ordered soon. Also, there are some tweaks that need to be made on my oscillator circuit. (Better precision resistors controlling the frequency and pulsewidth.)

So, the question is: How big a coil - ampacity wise- needs to be built to run the motor running the generator?

For instance (with made up numbers): A coil to carry 20 amps would need 1000 feet of #12 AWG magnet wire.

See what I'm getting at? Any ideas?

Keep chipping away folks,

glen

That seems a bit to much to me. considering we are only firing two coil sets at one time. Factors to consider are on coils weight of wire matched, Ohms matched or somewhat higher. Gage of wire will fall into the formula when the other two factors are calculated and is a variable. JohnStone and UFO may help clarify this issue but for now that is what I can gather.

Four phase oscillator / driver

Ufo requested for his current setup a four phase oscillator.

I threw some components into the circuit and ask for discussion. It is what I intend to build.

The reason for using a microprocessor is because the circuit with logic ICs is lots of wires to draw and one use only. A micro is much more precise and versatile to use.
@Lester: Some suggestions for i.e. snubber circuit? Suggestions for additional protection?
@Nico: Arduino connected correct? What about modified program? Where did you connect your POT / LCD exactly?

TBD:

• 555 NMOS (slow but 200mA source sink at output) or CMOS (fast but 8mA only) - needs to be tested
• Control for dead time and frequency: Pot, digital pot or by simple terminal program from PC (USB)
• Display required?
• Option for current measurements required?
• Use of reset at pin at 555 in order to prevent unintended firing of FETs while program downloed and aother actions.

With some additions (voltge feedback) this circuit can peform as SMPSU - not high end precision PSU but suffitient in order to control the voltage for our loads from battery stack or welder. It depens on your requirements and your setup.

Hello John,

Yes snubbers seem to be a "necessary evil" at these switching speeds.

The faster we turn off the FET the higher the flyback voltage will be (V=L x di/dt) and that's great for the radiant provided that the FET can handle the voltage. Unfortunately there is no hard and fast rule for snubbers: Sometimes the coil's inter-winding capacitance is enough to slow down the di/dt and in such a case a sunbber is no longer needed. For this application, it seems counter-productive to put a snubber because intuitively, it will snuff out the radiant lady. I'm sure you know that ladies don't like being "snobbed".

Alternatively, several high-voltage zener diodes in series with a high-speed diode (reverse connected to the zeners) will work in place of the snubber and this is preferred since it does not waste energy as a snubber does.

I would put the snubber and/or zeners across the coil, right at the source of the spike.


A reminder for everyone:
As we move towards high-energy coils (lots of amperes & lots of inductance) we need to keep the load connected AT ALL TIMES while we are pulsing the coil. Without a load the energy stored in the coil will have no where to go and it will seek the nearest discharge path and that's the FET. It might not survive the high-energy spikes.

Hello MR. John Stone!!


Nice, very nice, excellent!

We could always have the option to be able to control Frequency and Dead Times through our PC/Software programming...However, a Manual Pot should be there also to do Lab Practice without PC...As it will allow for other Applications like a Vehicle where Pot will be the Throttle/Accelerator...
Now the Current measurements Arduino Microprocessor would do...would be the one handled at Gates...but not at Drains right?

Display will be great, whenever not having PC nearby...

Dealing with this kind of Technology, so flexible, and Open Source... will takes Us all very FAR...to Horizons We have never dreamed off before...seriously...

So... We are waiting on Nico...to give the last final brushing......Then We will make a complete Diagram with Parts spec's and mounting Circuit Lay out ...sounds great.

I see it has several other PWM Programmable Ports (D2 through D13)...like when we get to Mag Three......So Cornboy555...read this and get ready!!


Thanks John Stone, Lester and Nico!

Circuit

JohnStone & UFO
This circuit looks good for the the new four poster and with just a few changes also for the prime mover. The manual pot is just a three wire plug in at Positive/negative/A0. Amps/temp/rpm can be added just as easily. It can be configures for auto start and stop procedures also. The secret in keeping frequency accurate is by making the frequency loop small and updating analog data maybe every second. This is exciting.

Yes Dana, exactly

Hello Dana,

Yes, exactly...it needs to be "expanded"...but we could go as far as our Grey Cells will allow Us...

Related to running Heavy Duty Motors like this Imperial and the Mag Three...it would be awesome...speed will get reduced from within "The Core" of the Spiral turning in the Machine...as also the Acceleration could be as smooth as we want...or as faster responsive as we select to go...

The Fact of being controlling the Input by their Quadrants...will also let Us Play with the Output at Generators anytime we want...or as we program them to do...For Example:

Phase One and Phase Three...are the "Typical Input Gates" that we have set at Motor original drawings...and Motor will run on just those two phase inputs..while we get energy out through Phase Two and Four...when we open from Input with another simple switching circuit that would activate a path for the incoming/generated flow ...say to charge batteries/capacitors,etc...

But it will also run with Ph 2-3 On...or Ph 1-4...and keep going...

Full Phase Run would be under heavy load conditions (since we get heavier torque and faster speed)...or whenever powering, say an AC that have a cycle when compressor goes on...then Full Four Phase activate...till it reaches the thermostat point...then goes off...

Many, many different options could be played with here...and basically for primary Lab Testing...we could check best outputs from Generators Ph 2-4 when Ph 1-3 are On(Motoring)...or Ph 2-3 On and 1-4 Generating...and so on and on...besides, it is also a great way to cool off coils-commutators, while performance continuing and we switch the energized coils positioning order...and it DOES make a difference...believe me...

I mean, look at the Spiral/Quadrant Partition I have displayed...We will be feeding ONLY at the accurate and exact points in TIME of the Spiral Cycle...and the more precise...the less our energy spent would be...once that we brake the inertia forces and have the flywheel effect on our side...and you know...that this motors brake the inertia very easy...

The point here is not stopping adding those drops of energy where it is required within the Spiral Cycle...so we maintain an equilibrium of rotational forces...at all times...


Regards and yes get excited...the Fun is about to begin!!

Hello Lester,


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

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