Thanks Tinman for the suggestion on the pwm. I did read through the rotary transformer posts. Looks good as to what youre doing. We are all a part of the puzzle. All the effort put in to these M-gs will bring us victory.

There so many variables to go through and endless experimentation. At times it frustrating, But then i say to my self. Wlll that didnt work and figuire out why. Thats progress and then on to the next step. So we are eliminating what dont want to work.

Yes, we do need to get everything turning the right way inside that case for the motor to accelerate under load. We have acheived that. next is recirculating the energy. that is the common goal. So keep up the Good work and keep pushing forward. thanks again for your reply.

HI again Mbrownn. Nothing to update. Since the last post. I kind of put this on hold untill I either get enough money to have this armature rewound or tackle it my self.

So it just been sitting on the bench for the last month and a half. I have made 4 replicas of what we do have. So that i have enough to experiment with. When I get the armature done. Te replicas all work the same. So that part is pretty well worked out. Next big step is the armature. Then I think the rest will all fall into place.

You may have to give me some advice on this armature again. I have two of them that I stripped the wires off from. Begging me to do something with them.

Hows your housing project coming along. Got to go plow some more snow, got another 11 inches of the white stuff coming this weekend.

So that all for now. Hiwater

Newbie Posts: 246	I haven't anything to update other than some activity has taken place on the lockridge thread on the energetic forum. We can have two plans of attack for moving forward. 1) rewind the armature and start recovery via the second set of brushes. 2) wind a trifilar coil on the motor. A lot of trial and error work here.

If i rewind the armature. I believe it to be wound directly across (180) from each commutator section. Or would you think that it could be that the windings are 180 and the commutator sections at 90 degrees from the armature windings. Guess it could be done either way. What do you think. Never done this before .So I am looking to my mentor for (your) oppinion. Thanks.

Newbie Posts: 246	I think it is your preference, normally the windings are at 180 degrees with the commutator segments set at 90 degrees from the coils and this is how I did it.

Was there quite alot of sparking on your commutator, when you run yours. From some of the other experiments that i had done there was a lot of sparking that could be put to use. Im sure it was up in the hundreds of volts.

OK thanks. Im going to give it a try and see what develops out of this. This is a first for me. I have some smaller heater motors. Im going to try it on

one of those first to see to see how it reacts. They look like they would be easy to do. Have the right size wire for those. So hopefully i can get this done in the next few days.

I havent had much sucess in rewinding these armatures. I tried 3 of them all failures. One I had shorted, the other 2 wont turn. They have a

magnetic feild but wont rotate.

Question---- Do you think the armature wire is to be cut off after being connected to commutator segments or continue to the next set of coils
with the end of that wire connecting to the commutator winding where I started when all the windings are in place on the armature.

Question--- Windings? Do you think they are all wound the same direction. I was doing one cw and the other side ccw. It locks up then.

Going to leave it till hear back from you. Im burnt out on armatures.

Newbie Posts: 246	Each coil was separate so the wire is cut off. All my coils were clockwise on the armature. Remember you need to connect to the commutator segments at 90 degrees to the coil to get the timing. Winding clockwise and anticlockwise will cause the armature to oscillate instead of turn although it may set up an interesting bucking arrangement.

Ok, i can see why the armature was chattering,because of the 2 opposite wound coils. I did have the segments 90 degrees to the coils.

I had my wires one continous wire. So theres part of the problem. Another question that i just thought of is----after the first 2 initial coils.

the next 2 coil windings i would assume now that they are laid in the armature slot next to the first and second winding just one slot over going in a clock wise manner. I had mine set up in the middle of the first and second winding armature slots. STILL IN THE LEARNING PROCESS.

Something else came to mind after posting. What kind of speed did you get out of your rewound srmature, by cutting the wire off at the comm bars. Seem like that the armature would sacrifice quite a lot of rpms. By running one long continous wire to all the bar sections wouldnt we get more of a back spike or does that take away from the wave winding.

I might be able to go in on a lap wound an find the 2 wires that have continuity on the bars that are 90 degrees to the winding and cut them.
this may work for what we need. have you ever tried this. Dont know what kind of a winding that would be then.

On 3v i was getting 1500+ rpm, I didnt have recovery and the armature was arcing quite a lot even at 3 v

What i was trying to say was each coil arrangement, must be started the next slot over from the first and second winding set. Dont know if that helps any or not.

Those recovery brushes must be picking up hundreds of volts which have a negative sign going to a capacitor then coming out of the capacitor
with a positive sign for the motor run.

Going to try find some more info on the wave wound armaures. I did find out some of the Old Model t cars had a wave wound armature on the long shaft generators for more voltage. Been trying too locate one of these. But havent as of yet. I believe those were all in series with theend of the coil windings connected to the beginnig of the first winding on the same comm bar. so all of the windings would be in series with the armature.

I did some calling this am to a couple of rewind shops . Do you remember when we first started talking about the armature being STAR wound.

I cant recall what the reason was that the armature may have been star wound. If you can remember can you relate this again to me. I did find a place that can rewind the armature in a STAR winding.

He says they do it all the time on tractors and equipment using generators. So i need that info from you. Then any questions that you might have

that i should ask him. i can also Give you his e-mail address if you want so maybe finally get this worked out . He does know some about the wave winding also.

non interconnecting Star winding is the term I used at first before I was familiar with wave winding so don't let that mislead you. Ideally we want it to be non interconnecting, that is each set of segments on the commutator is connected only to one set of coils. Most wave windings have groups of coils connected together but each group is separated from the next, so i understand.

I still don't understand exactly what your trying to explain?

Im starting to uderstand a little about this armature winding some. what i see is that it would be a pulse motor. should have known that from a year ago when we were talking about it then.
After putting in the first 2 windings------ trying to figure out where the next 2 go is the problem that Im having. i think i have some of that figured out.
As time permits will continue to work on that.
i do have one of the extra brush holders in, but the second one is a problem, not much room to work with and the angle is pretty critical there to get to lay in where its supposed to for it too work properly. So another area that has to be worked on also. If there are questions or directions feel free to speak out.

Good to see your still around. In survival mode any way. Hope you find another job something that you enjoy doing. My self i havent done any thing on

the project since i last posted. I did talk to the rewinder I mentioned about. He has rewound armatures to make pulse motors. He said they are slower starting but once they get going they fly. He wants me to come down and see him. soon as work slows down some i am planning to do just that. He is more than willing to help. Right now its the time thing. Not enough hours in a day. So soon as i get time Im going to resume work on the project again.

If any thing develops Ill keep you informed. Have a GREAT day.
