Pulse motor build off time.

[MarkE]

It's looking good.

It's even more funny how some peeps react when they build a PM for a PMBO saying that the way they build their PM is the only way to build one and even write about it in that manner on many forums...lol
LOL...if you can't get your PM to run like mine do on that kinda input than you still have a long way to go...

That's your believe thinking that people need to show meters on both sides of the PM or show anything for that matter..no they don't...it's their desicion to do so or not...

Me doing magic tricks...lol...think i need to invite Stefan to see this one first hand...good thing you haven't seen my massive PM running at nano input some time ago...lol...

Have fun...

If someone knows what they are doing and keep the mechanical losses down, then sustaining the motor at speed can take very little input power.  Then it is just a matter of how fast they want to accelerate up to speed, or alternatively how much power they want to limit themselves to during the acceleration ramp.

About five years ago there was a scam artist by the name of Pete Sumaruck who got lots of attention for his "zero amp" motor "technology".  What he had done was modify an off the shelf AC motor controller's acceleration ramp to a very slow rate.  His demonstration was to hook up several sizeable AC motors using small gauge wires, and of course operate them without any loads.  I think Stephen Greer's group ended up giving money before the scam fell apart.

Hi all,

This is my understanding of how a real pulse motor should work

Very impressive looking Tommy.  I think the Las Vegas bookies have you marked as the winner.

So i do think that this one have some possibilities...meaning that if the core and the coils are say "tuned together" you can have more output and maybe have Lenz assist you instead of working against you...
With tuned i mean...have more eddy currents coming to the party and/or more capacitance in the coil...so many posibilities here and that's a good thing...

Hi Mister Caribbean Roots,

Thanks for your kind answers, I appreciate them.

Re on the several iron rods bent and taped tight for the ring core: Hopefully you used 'thin' rods and you isolated each rod from one other to minimize eddy current.   
IF you do not happen to have thin rods for your next build, try to use garden wire instead which are PVC or enamel insulated and made of iron and thin enough like OD 0.4 to 0.6 mm or so, and just form the ring diameter you need by looping the insulated iron wires.  I know it may take quite a long piece of garden wire to buy and form the ring core with a decent thickness to fill up the ID of the coils but it may not be so expensive at hardware florist shops, Chinese merchants bring over also such wires for florists.
Also another possibility is to use welding roads as are used in Bedini pulse motors for the coil core, these should also be isolated from each other by painting them first. There is a recommended type of rod they use, I cannot recall it at the moment but it can be searched easily. Though these are more rigid to bend than the PVC isolated iron wires having an OD < 1mm, they may be worth using too for the much less eddy loss what thicker iron rods with OD > 4mm or higher may manifest.  But you may know all this... 

Okay on the LED lamps, I agree with all what you wrote, including the DC-AC issues. Driving individual LEDs by AC can be especially misleading because current can flow in the forward direction to get light at peak voltages exceeding the forward voltage threshold of the diodes, rendering LEDs a deceptive nonlinear load which actually 'eats' output during ,say, 25-30% of an AC cycle only... 

Yes, I meant on 'tangential' as you actually placed the coils, a good representation for this is shown by Naudin on the left hand side part of this picture versus the normal coil position on the left, here:
http://jnaudin.free.fr/images/magconfig.gif   from his site: http://jnaudin.free.fr/html/mromexp.htm  probably you have seen these. (By the way, the Mini-Romag generator is an interesting setup in itself, it is a pity nobody turns more attention to it.     )

Also, John Bedini showed a pulse motor with a single big coil also placed 'tangentially' to the rotor magnets, he coined the 'zero force motor' name for that, see this video as he himself demonstrated it: https://www.youtube.com/watch?v=3kpDMMcNQxc
He claimed in the video the setup had no bemf, no Lenz effect and indeed at the input (small) current level involved, together with the huge coil size versus the relatively small inducing rotor magnets this sounds correct.  I am sure the input current would go up when the motor shaft were to be loaded mechanically, that would be a good test to show how Lenz-less the setup is.   

You mentioned 'tuning' in connection with eddy currents as a possible advantage if I undertood you correctly, this seems to be the only issue I have to ask how you mean.  Because I think that if there is any eddy current loss inherent in the ferromagnetic core of a motor or/and generator setup and when this loss becomes less when the generator is loaded (and as a consequnce the prime mover input power reduces and overall RPM increases),  THEN you simply 'tune out' the eddy current loss present in the core by the effect of the load.  I believe if there is such 'tuning out' benefit in setups with air core coils to get similar phenomena, that would be something really useful.     I think any eddy current loss in a ferromagnetic core is unwanted, no need to build-it-in in advance and then trying to 'tune it out' to simply bring back a certain part of the input power you are already paying when the setup runs unloaded.   

Thanks for your time again.

MCR,

One thing is clear to me is that you want it your way no, matter what.

Your comments on low power PM is like a the wind blowing smoke, it's only when you pull power from your so called efficient pm that really matters

You're right, you don't have to show any input or output of power, so why even think you can try to fool other with this clown act of showing super low input of power in the first place?

You're comment on RWG research asking others how to use hall effects just show me you know very little about electronics.

You're like a car salesmen, adding more pulse motors on RWG forum hoping to win a prize, when the last few ones did not work

I have better things to do then to add any more comments to you, good luck, and may the best integrity person wins!
