When you wound the thing did you put a diode on the end of the windings. Your motor as described will only fire once per revolution also so you have to have a diode on the end to keep the power from flowing backwards.

With 18 your gonna need at least a 12 amp diode with surge of somewhere like 50 amp.

Maybe try smaller wire like 24 - 26 if you have it. If not get s big diode and add to the end.

Another one interested

After reading this when it was 10 pages I went out to the garage and found a 2 pole stator, 12 slot rotor 12 volt motor. It didn't state its rpms, but says 12 volt @ 9 amps draw. I have rewound it with two coils 90^ off, with 40 turns 22ga wire. I but it all together and tested with a cordless drill battery, it wants to spin the wrong way. But it seemed to take off fast and had some torque, only ran for a few seconds. I am going to flip the coil connections at the commutator to fix the direction issue. Here are some pics, looking forward to sharing my results.

Excellent

Robbush,

Thanks for the pics. This is the configuration I originally thought would work very well. You will get 4 power pulses per revolution, so be careful not to raise the voltage too high. It should really rip on 36 volts with excellent torque.

It looks like you still have some room in the rotor slots, which you may want to fill with more wire (later).

The work on the brush system looks very good.

I look forward to your test results.

Awesome write up Matt! Great pictures, don't know what kind of programs your using, but that is very impressive.

Had a bad morning. My plan didn't work. But lesson learned.

Great Plans!

Alright I wrote it all. The schematic, the details of the parts, the brush wiring, and the motor outline.
You can cut and paste from below or get link here. Motor Details



Any questions or improvements let me know.

It not going to rain tomorrow so I'll be building something to test the the torque. So most likely I won't be around during the day, I'll be in the shop.

Enjoy
Matt

Matt,

Thanks for putting this together so nicely. Just to help people understand a few more details: this motor operates with ONE PULSE PER REVOLUTION and uses what we have been calling the "zig-zag" winding on the rotor.

Here is a hot link to the motor being used:
24 Volt 250 Watt Motor with #25 Chain Sprocket for Razor E300, Mini Chopper, MX350 (Versions 9+), Pocket Mod, Pocket Rocket, and Sport Mod

Here is a hot link to the diodes:
MUR460-E3/54 Vishay Semiconductors Rectifiers

Capacitors with these ratings have gotten quite expensive, so you may want to look around in the surplus sites. I didn't find anything under $30 each.

A similar Battery can be purchased here:
12V 5Ah Sealed Rechargeable Battery
This is a pretty good price for brand new SLA batteries.

Hope this helps. Thanks again, Matt.

No problem.

A friend of mine handed me those caps and say "Have Fun, Be careful". Or I wouldn't own them either. LOL

I think you can use just about any cap you want as long as it is a under 10k uf.
The point is to split the incoming power up so you unload your coil at point that is at lower potential but still in the system.
I would dump it in the battery but looks like a pretty big load to the generator and it does not take the charge usefully.

try to minimise Mister Lenz as a gnome

Hi all

Hi Matt

thank's a lot for sharing your great work. and i am sorry that your big fly wheel does not bring you the power you expected.

But if i look at your shematic, i see that you fire 3 consecutives collector sections,
which greatly consume current and this ,on a long time and the longer the consuming time is leaving a longer place to Mister Lenz (counter generated voltage ) to oper, and this against you.

And secondly as your brushes are 90 degree of each other , as per your shematic ,they do not contact at the right place for the recuperation of the BACKSPIKE (radiant energy ) but they are recuperating the counter BEMF ( this is exactly what Mister Lenz expected you would do ) which slow your rotor down.

Sorry to insist on the point

but we need ONE SINGLE "GUN SHOT" PULSE per revolution, and nothing else.
Each time we try to gain some more pulse ,Mister Lenz is behind the corner, and will slam his baseball bat right in your face. So do not let any chance to Mister Lenz to be TALLER try to keep him at the gnome size.

My point of view

And if i am out of this thinking here ,please mention and i will stop my intervention.

Good luck at all

Hi all


Hi Peter

i reread a lot of pages ago to restructure ma mind on this project

And on post 957 ,

i would like that you further explain your mind, because i see a great possibility of improvement here

Thank's

Woopy,

Results of a real test model ALWAYS trump theories to the contrary. In this case, Matt's test motor is running extremely well, producing high speed and torque, and returning a reasonable amount of the input electricity.

I suggest that you build your own test model according to your own understandings and let us know how that works, and not waste too much time trying to convince us that Matt's motor is theoretically flawed, which does NOT seem to be the case, based on actual performance.

With all respect,
Peter

I think you probably have to build one to see. It works rather well. As far as torque now I am in the process of testing that.
I would have to say that you are probably wrong. I have never seen such speed at such a low amount of power. And of course the power draw will go up as the motor starts to do work, but that is not the concern here. The goal is to do 1 hp or a fraction of for less than 746 watts per hp and do it with a regular motor. Period.
And the lower the better.

OOuups

sorry Peter it was your post 959 and not 957


and for my other post , please see my aim

i am not trolling here (as my youtube video are showing my work and results.)

I am really trying to get result and be sure i am far from a theoriser.

Ok but it is your thread and i apologise to disturb really sorry

good luck at all

Laurent

Hi Matt

TOTALLY with you

And surely "bravo " for your fantastic work

YOU ARE A MAKER and i am sure you will find a good result


All the best to you and i will rejoin you on the "bouncer experiment "

Woopy,

I'm still confused. This thread is on POST #510. What thread are you talking about for POST #959?
