MG3 : Pulse Motor Generator

[demnlordd666]

these are an extension of the battery charger right? using *free energy* to charge batts at below normal energy costs? (thanks wikipedia) these are to be scaled up and used as generators? is this the same inventor who did the weird commercial w/ a bunch of dead batteries and a big silver thing on a rolling table? wiki mentioned a commercial and I remember one, same thing? whats the end goal? sorry I keep seeing these things pop up in my searches, figured I would ask a few Q's.

for a standard dc motor, a skewed desgn is strantard way to improve torque...

by a chedp chordless drill then by a expensive one look in side.... the expensive one have skewed motor

[introvertebrate]

@eloid777

Yes, it can improve torque by making it smoother, but it doesn't produce *more* torque. Things like drills need high torque at low frequencies and so eliminating cogging is desirable.

[eloid777]

@introvertebrate

stepper and severo motors also use this( skewing) and there torque profile is very demanding at a very "wide" range of high/ low rpms / loads/ start ups to excleration to ramps so your not sell me that it does not help.

[introvertebrate]

@eloid777

I didn't say it doesn't help. I just said it doesn't add to the torque. I'm not making this up. Try and find one source that says a skew design *increases* torque. I have already provided you with one that says it reduces it.

[eloid777]

@introvertebrate

you still not understanding the design idea,,,, your thinking of the skewing only and clogging. the coil would not circular but elongated lobed over 3,4,5 ,6 magnets... increased flux captured ....When the number of turns or the flux increase ( more surface of magnet face cut) thus torque increases.

[introvertebrate]

@eloid777

let me know how it works for you ;) we'll compare notes

[introvertebrate]

@eloid777

Look up "cogging torque" on wikipedia:

"Almost all the techniques used against cogging torque also reduce the motor counter-electromotive force and so reduce the resultant running torque."

[eloid777]

you note your using air core..... no... metal core?

[introvertebrate]

@eloid777

No metal core... just air ^_^

[eloid777]

do search for Movie Bedini Box Motor.wmv on youtube you see the skew magnet design.... i refering to.

[eloid777]

question ? why are the magnets on the rotor spaced this way, why not change your design the  magent on the roter two have 3-4 row skew in such a way there are 30 deg from each row and wind your coil to to rectangule lob to obtain the magnet

skew motor design give more torque that what u need!

[introvertebrate]

@eloid777

Won't that just reduce cogging? 

Cogging isn't a big problem with this motor since it uses air core and has an appropriate flywheel :)

[eloid777]

@introvertebrate this how improved torque isacheive in more expensive Dc motor designs,,, The improved cogging is a side effect from the design... which doesnt hurt...how many trigger coils do you have in this design?

[introvertebrate]

@eloid777

Eliminating the cogging doesn't increase the torque. It makes it smoother which is desirable in some applications but not necessary unless you want to run a load at very low speed.

There is only one trigger winding on the mg3 :)

[skycollection]

what is the IMPUT voltage...? are you using the bedini circuit, and bi-filar coil...?

[introvertebrate]

@skycollection

about 12.5v... 24 x transistor bedini circuit.... 5 x quadfilar coils, 1 x quinfilar coil.

[mcorrade]

very nice. Are you considering a self runner?

Alway like your work! It was your bedini schematic that got me started......

[stocktoncs]

Awsome work! Keep it up!

[tyrodogg]

Great to see another video from you. Good Job.

[deepcut71]

Very nice. What make and model is your tachometer please ?

[u2btchr]

Seph - Good job! It is obvious that you have put much thought and planning and time into your MG-3. Keep up the good work. You are a motivator to those of us that are still learning and trying to capture this knowledge so we can use it.

Look forward to you next video.

Anything you can add to 'the underground lab' site on how you have accomplished this would be most appreciated.

the ole tchr friend

[Rawbush]

very nice, looks like you are getting a bit of torque out of that motor. Keep up the great work. Peace rawbush

[introvertebrate]

@Rawbush

Yes :) Have you seen the "Bedini Motors have no torque" video?

This MG3 can turn that same fan at the same speed for 15% less power than the original brushless motor could.

[ajungulak]

nice work :)

[marthale7]

Nice work. I like the fan blade.

[pandamanman89]

u should start scalin up next, try and generate some real power. i'd buy. good to see a post btw.
