My 76,000 rpm pulsed dc motor

[mnsman]

Hi Jim,

There are several of us on this forum that use the Picaxe microcontrollers. I use the 18x version. They are reasonably cheap and the programming is not hard at all. You can down load the instruction manual for free first and see what you think about the programming. The 18x has an ADC (analogue to digital) input and PWM (pulse width modulation) output as well as regular switch input and on off output. Following the manual you can probably learn basic input output commands in one evening. RobotShop is where I got mine from. There is a project board that makes it easy do your first projects until you get to the point where you want to build your own boards. I am no expert at programming it but I can usually get it to do what I want and I have only been using it for about a year. There are some examples of programming and use of the board in the "Use for the Tesla Switch" thread. Most of those are way more complicated than what you need but they will give you an idea of what can be done with them. Hope this helps some.

Hi Carroll,

I was advised by a programmer who wrote the muller motor controller program for a well known youtuber. He said that the arduino wasn't fast enough for this motor. The mega2560, which I have, only runs at 16Mhz. Somewhere in an unknown location lurks my netduino which runs at 48Mhz. I asked him if that was fast enough and no reply. So my concern is how fast is fast enough for the micro controller. Don't want to buy yet another controller to find out it can't handle it.

I briefly looked at the PICAXE controllers and found they run at either 32Mhz or 64Mhz. Is 64Mhz fast enough? Do I need multitasking? The reason I question the multitasking is because I want the controller to also furnish the timing signal for the HV discharge circuit too.

The aforementioned programmer recommended "something like the Maple or the Fez Panda boards or something else". That narrows it down. lol In looking at those boards they are 72Mhz boards.

I appreciate your suggestion but I need someone to tell me with authority what controller would be best suited for this job. Don't want to buy another without this confidence. I'm looking to pass the buck. lol Rather than do a whole bunch of research myself. I know that sounds lazy and it is to some degree. I prefer to think of it as smart and resourceful if I can in fact find such an authority. Ideally the authority would volunteer a bit of programming too. What r the odds? Like you I can muddle my way through it but there's the learning curve again. Collaboration is where it's at.

Is one of the 64Mhz PICAXE controllers the correct choice? Fast enough?

Someone please let me know.
Thanks for your advice.
Jim

no no no

hehehe

just add relays on pos feed and neg feed ... leave your motor alone.. you apply this in curcit with motor run motor as you already are ..

then connect both relay coils togather and intrurtp supply to motor ..

if useing mosfets.. hehehehe yea they dont like it ...
take the right percautions .. or you will blow em ..
i blew 50 mosfets in 1 week end ... threw em out after that ..

W

i was finally able to get the mosfets to work but .. left em alone .. i lit a 40 watt 120vac lite blub from 12 volts or something .. might have been 60 watt this is so long ago i almost cant remember now ..

freqs of conversion are what you are interacting with ...


ps i would not waste my time with microcontrollers or mosfets ... just my 02 cents

i have worked with freq gennys and fets much and .. they in my opinion cost time and money
tesla did it with FREELY VIBRATING CIRCUITS .. KINDA LIKE TUNEING YOUR COILS AS I HAVE EXPLAINED ..

but freely vibrating and mechanical spin is a fine ballance act hence the resistors ...
take motion away .. it is a no brainer ...

W

[willy96]

never mind ...


you dont get it ?

do relays operate about 7.5 hz?


hummmm

see you dont get it

sorry to have wasted my time and effort perhaps some others clue in ...


W

i can see now how bearings hinder your device ... yet there not a majour concern in mine.. my stuff is all quite advanced altho verry simple to understand ...

have you ever built a jt? you need to do that to understand my work ... and in essance yours too ...
because that is aside the 1k resistor a freely vibarting tuned copper coil unit so remove the resistor you have a transistor driven freely viberating curcuit .. ok this is your motor ... but you use the hardest way to acheive the same effect ... ..

now on the supply that goes to this freely vibrating circuit goes the relay .... let your motor spin at the speed you set it at ... turn it off and on ... while running at the speed you set it at


o my my

if you cant understand this .. i will waste no more time here ... cuz this is a baby toy ... simple simple simple ...

ok

You make a valid point. Mine is a one wire pancake coil. 13 stacked and wired in series. I found it difficult enough to wind these. Bi-filar would complicate it that much more. So little time and so many things to try and that is one of them. For the time being I am testing what I have. Maybe in the future.

Thanks for that suggestion.

Sandwich the two spiral coils one over the other, then attach the END wire of one to the BEGINNING wire of the other. This will work as well as rewinding a bifilar.

That's precisely how they are connected now. Wired in series... output to input, output to input etc. Unfortunately that's how they will remain. They are entombed in a pvc cap with epoxy. Had a major problem with my second coil. I clamped it while it was drying and the next day discovered that one of the solder joints got broken because of the pressure. Fortunately the glue wasn't completely cured. Tore into it. What a mess but fixed it.

Still think testing the bi-filar would be a good idea as you suggested.

Thanks for the suggestion though.
Always looking for more. Keep em coming they're appreciated.

Sorry you think that you wasted your time. Perhaps it's my low IQ. or Perhaps it's your CRYPTIC delivery. And darn it I misplaced my decoder ring. For some reason I don't think you've said all that you have to say. Not here to squabble.

Any reasonable and understandable suggestion will be entertained.
Jim

Hi mnsman,

Do not expect too much of Willy (many aliases), since he is been flirting with FE forums (a few years), he says he will help but instead confuses, mixes in a few music videos, speaks of extraordinary experiences and results but in the end nothing comes out of it except sparks and smoke. If you don't understand his gibberish diatribes which are childish in nature, he then proceeds to insults. Ignore him and get on with your researches.

Take care,

i didnt waste my time .. but i thought you were with me here bro .. this is so simple ... but i see you miss the simplcity in this .. im trying

i dont have a lot of patience but im trying

please use a battery as source ..

we can start there..

W

odds are we will not blow up the battery .. next after running on a battery ... and your motor is up to speed disconnect a supply wire .. and observe the result AT BATTERY POST ...

ill try agin ok here i will use my videos ok to explain to you what i mean ... i have over 200 videos on youtube .. all the same .. thing

IST TPU ROTATING MAGNETIC FEILDS - YouTube
now this is a single frequency hand pulsed pancake coil and torrous pancake wound atop it .. no big deal .. but look at the sparks .. if i were to make that video device a freely vibrating spinner ps its an ETHER SPINNER...... UMMM as it is ... it would be then a 2 freq device if i were to tune it to sing .. then you have what 1 of my motor coils do in the video showen ... of my model A

now tuneing the freely vibrating circuit .. in your case for 1 its not freely vibrateing but truely it doesnt matter .. as long as you tune the speed to the right speed now intrupt it !!!!!

at the source ...

like the video showen ..

W

im not sure if any of this will help you as truely i personally think your motor design should be upgraded first ..

by better design ... i mean 2 pancake coils 1 on bottom 1 on top .. magnet as you have it in the middle of the 2 pancakes thease pancakes should be bifillar and hooked up as TESLA says .... out of the first one into the second one .. he states in that pattent that this is 250 000 times as great as current coils for electromagnetics ... in that time frame ...

so 2 of em they both should be set up to repell the magnet ... ok how ever you do it ..... there more than one way to do this .. 1 is polarity other is windeing dirrection .. or you can use it as a trigger coil ... but better results will bee seen if you power both .. higher speed .. now you can use a 3055 npn ..

there cheep and take a beating ...
if you dont use a resistor its freely vibrateing .. that means it will run at its natural running frequency so your motor will run at highest speed but tune to the coils ... now if you stop the flow from the source with this motor running .. spectular results are seen ..

To all,

Load test performed 12-12-11

Load: 82 ohms 5W rated; 83.2 ohms measured

Driver: Fairchild FQA5N90 900V N-Channel MOSFET 5.8A, 900V, RDS(on) = 2.3 Ω @ VGS = 10 V

P-Motor load test 12-12-11 - YouTube

Planning on running same test using a different power mosfet to compare results. However the load will have to be different because I fried the resistor used in the 12-12-11 test. Too much juice put through it.

Hey,

15.5V across 83 Ohms gives about 2.9 Watts in power. Can you try double or triple the Ohms with the same setting and see if power increase? I think higher Ohm value cause motor speed to be faster, therefore, would gives higher watts.

I have to see what resistors I have "in stock". lol I know I have some 2.2K 5W. Could put 2 or 3 or more in parallel. I presume you watched the last video. If so I made some errors in my readings. I annotated some corrections. I stated Volts per division on scope wrong a couple of times. It was getting late and I wanted to get it uploaded. Whoops. Will try your suggestion tonight. Going to put a bigger cap on tonight too and charge it up higher. (edit: Using different powerfet next test -it doesn't charge cap as high so probably will stick with the same cap for performance comparison of the two different mosfets.) Hopefully the different resistors will hold with a bigger charge. Need better heat sink on the fairchild mosfet. Overheating may have caused problems too. Maybe we get to see some smoke. lol

Load test last night a failure

To all,

I tried running another load test last night 12-13-11. First off I had a failure of my trusty stw50nb20 power mosfet. Then I had two hall sensor failures. Rewired to have the hall run off of only 12V vs. 24V. Need to add switch and fuse for that part of the circuit now. Added banana clip pig tails for battery to get rid of test leads as connection.

After all of the mods and parts replacements... I used a 270 ohm 5W risistor as the load. It was going well until I took off load and charged the cap up to about 300-350Vdc. Put it back on load and poof there went the resistor. That was the end of the night.

However, yesterday I finally got my el-cheapo db meter in the mail. So this morning I fired up and recorded a small clip of the test. The meter needs a new bat but you get the picture of how loud it is even with a dim display. Approximately 120db max was recorded. Loud.

According to this site Dangerous Decibels » How Loud is Too Loud? the permissible exposure to 115db is 30 sec. Glad I have ear protection.

Work needs to be done on circuitry to stop the blowing of fets and halls. Need to isolate hall with opto-isolator and add a RC circuit to slow down the applied voltage to the driver circuit at initial turn on. In other words, make circuit input voltage ramp up from 0V to full power over several seconds. The silicon doesn't like the immediate application of 12 and 24Vdc.

Tested different power mosfet STW11NK100Z. The cap charges in a big hurry to ~450Vdc approx. 48 sec. No other data analyzed such as current input, rpm etc.

Link to latest video on youtube of decibel test and update. P-Motor update and decibel test 120db 12-14-11 - YouTube

Tonight I want to add bigger recovery cap, add RC circuit and use the stw11nk100z with three 12V bats. Then I will try another load test with just 2 bats.

Suggestions?

Jim

2 much juice lol

I guess it's bad to charge up capacitor and suddenly discharge it. That's a lot of energy going through the resistor for a short period of time not allowing heat to dissipate. I think it's safer to have a separate pick up coil for load testing. Fly back EMF energy comes from the supply itself and it's a good chunk.
