Almost ready to "Rock and Roll"...Baby!!

Hello to All,


I just finished the Secondary...prior, I did two Primaries.

[IMG][/IMG]

[IMG][/IMG]

[IMG][/IMG]

Primaries are wound with 16 awg, around 65 T per layer totaling Four(4) layers...Total Resistance 0.5 Ohms.

Secondaries are wound with 14 awg, around 55 T per layer at a Total of Eleven Layers (11)...Yeap...lot more than Primaries...did not have more room otherwise I would have kept going...

I used a special tape that cost me a lot of work to finally locate and order...:

POLYESTER 2MIL 425º F TAPE

These people are awesome, lot of goodies and good prices as different sizes and colors...

I used first a layer of Fiberglass Mylar Fiber Sheet used for High Temp Electrical App (I use it for Motor and Generators Hedges)...secure it with tape and start winding...this way I can slide off whole coil out for testing...plus by using tape at every layer, have no chance to mess up layers by forcing one wire from another one etc,etc...plus gives a fully strong coil after is finished, even out of core.

Now, while I was winding Secondary...and after exchanging some mails with MM...about secondaries Output...

And I came up with this idea, which I did not applied on the secondary winding shown on picture above...but I definitively will in the next!!

If we wind Secondary, and every layer we extend wires out, just in a loop...then later we cut it and mark it (Layer 1) and so on...then we could read our output per layer in order to be able to calculate later how many layers we need for System Supply...

Also, and very seriously...that way we do not go overboard...You know what I mean right?...Yeah, I meant going too far in Kilowatts at output which could be really dangerous by being close to Megawatts...


Tomorrow Land...I will be running some tests...Oh!, and forgot...My weak PSU will feed each Primary at 6V and 10 Amps...and so far magnetic field looks good...have to test with this Secondary what is the Output.

I believe the right Input (whenever I get the ordered 900 W Linear PSU)...should be in the range of 40V and like 5 Amps...I don't think it would need but maybe -/+ 10V and -/+ 1 Amp more.

See you all tomorrow...and maybe we will have some nice Christmas Presents then...

Thanks All, for your kind words.

@UFO, I will do as you suggest with the bulbs and scope might take a while, Christmas stuff. The motor is total overkill, funds are tight these days and it was on hand, just as the brush,s and holders from some cheap vacuum cleaner motors i had.

@ Mm, If you can mill a slot in brush carrier like i did you should have little trouble balancing it, having it on the outside will drive you nuts trying to get it to run smooth, that's why my switch was Take 2.

Best Regards and wishes to you all, Cornboy.

Good to Go

Thank you Glen, i like that the bobbins are very easy and cheap to make. the cloth i use is recycled plastic bottles. COOL !

I think i will stick with the motor i have found and posted earlier. at a light to light medium load i figure it will pull a 1 amp load and that is good enough for me especially at 16 bucks.
would like to know more about your 3 inch cores as i think that is a sweet spot for core size.
and i to have a heavy duty commutator coming and as i have stated before i will do both but will end up with electronic brush simulation in the end just so people have a choice.

we are advancing very well and will all be testing shortly.
sort of like a pie in your face kind of thing to the other thread.
oh, i'm sorry, did i say that...... OPS !


i forgot, we are on the same side, em, i think.

Below is drawing of commutator set up i envisioned.

Update

Greetings all;

@UFOP - I will build both mechanical and solid state switching. (I know, but I just can't help it.) Thank you for posting those pics, they will help greatly when building mine.

@Cornboy - Looks great. Man after my own heart - uses wood!!

@Shadow - I'm envious.... keep going man.

@MM - I love those coils and bobbins.

Take a look at the Razor motor: New Razor MX350 V9+ DIRT ROCKET BIKE SCOOTER Electric Motor | eBay

These can be found at wheel chair repair shops, too. Electric scooters, and so forth. The motors can be rewound and made pretty efficient.

My machinist is picking up the 3" diameter core material today while he's in Kentucky. Got enough to do 7 sets. He will 3D print bobbins for me. (That is just so neat, and I really appreciate it!!)

Metals Depot had pretty good pricing. Metals Depot® - Buy Metal Online! Steel, Aluminum, Stainless, Brass

The commutator sales lady emailed back, so I'll look through their listings and get the most robust available, along with brushes.

My FETs have yet to arrive. Must be on the slow boat from China. (Oh, well.)

Keep trucking guys. You are all doing great work here!!

Switching

Nice job on your coils Mm and Shadow, and your switching UFO.
@ Shadow, what kind of switching are you going to use?
from: CORNBOY 555

I plan to use MM's electronic device.

I have some time so I am going to attempt to
build a rotary device like yours, UFO's or Doug1's.
Working on it now.

Awesome!!

Hello Cornboy!!


That looks really awesome friend!!!

Very smooth and neat!!

What I recommend is to add some power to circuit (like 12V) with just a couple of automotive incandescent bulbs instead of primaries to then scope signal from both bulbs positives and common negative ground to source and probes.

This way you would be able to check your Part G wave amplitude and depth, plus check if brush still holds good contact at higher speeds...if it don't it will go flat line.

But I believe because of brush positioning being vertical it will not be affected by centrifugal forces...

That Motor is a killer monster!!!...You wanted to make sure there will never be Power Outages by "small" motor failures Uh?...

Great job...now you are ready for the electromagnets!!


Regards and All the best!!

Nice

Man, that was almost better than a porno flick.
very, very nice Cornboy. at 3000 rpm and dead smooth, i think you are good to go.

Nice work also

Thanks, nice work your self Cornboy.
maybe try some bobbin construction, sure makes winding a whole lot easier. slipping on bobbins is easier than winding direct on cores.

oh and when your cores are finished and pumping out some serious va. all the pain in the arse work will seam trivial and most likely forgotten.

MM

[Cornboy 555]

Hi all, have test drove my switch, and was surprised just how smooth it was first go.

Took it up to about 3000 RPM, no trouble.

Ahh well, no excuse now, will have to chop up my tranny,s to make primaries and secondaries, winding will be a *****, being rectangular.

All the Best, Cornboy.

[Cornboy 555]

Nice job on your coils Mm and Shadow, and your switching UFO.

@ Shadow, what kind of switching are you going to use?.

Finally got some free time to work on my switching today, hopefully will be able to post some pics soon.

Regards Cornboy.

shadow119g STUFF

Here are three completed components.

brass screws

I was concerned about traces of magnetic materials in the brass. The picture shows a brass screw hanging in front of my huge magnet not being pulled toward it like the two steel measuring squares being magnetically attached to the magnet.
So far, I am happy with my bobbin less winding's, but?
The bobbins were machined for a pressed fit on the iron round bars. I had two break because they were a little to small. The worst part of it is I have to use my metal lathe to wind my cores because there is no way to attach the round iron bars to my $45.00 winder.
All and all I think your bobbin idea is better all around.
Thanks,
Shadow

Pic

Shadow;
I looked at pic twice....what is it????
and what is wrong with your bobbins Shadow ????

yes that motor does look great for many projects. the first one is absolutely beautiful but second one is less amperage.

that is great your brass is non magnetic as heating would be an issue.

UFOP;
thanks.... and yes, i like the top one also and if it comes down to it ill build a robust controller my self as i have many parts on hand.
i see they are going bonkers over core.
one man's failures are another man's gain.
well no eddies/hysteresis is all i can say.

Mm

[Ufopolitics]

Found what looks like a very good candidate for motor drive to test part G.

also they carry the controller plus a heck of a lot of other things one might want or need.
pic below is motor, as you can see very good size and robust.
just about the size of my cores after i cut them.....nice !



or this one.

3-PHASE BRUSHLESS MOTOR, USED | All Electronics Corp.



UFOP;

what do you think of these motors ??????

MM

MM,

You know the ones I have used so far are brushed motors...no controllers required but my other 18V 3A PSU...where I can regulate separately V & A.

I have no experience adding such load as brush with springs plus counterweights on a 3 phase BLDC.

However, by the Body size I like the upper one...lower seems too small body.

And "cheap" small controllers when loaded, FET's will start heating up...rather use good ones which have better heat sinks, and FET quality...more money though.

So, IMHO, I highly recommend to go simple by using brushed ones...no controllers.

EDIT...BUT...in the RC World you will not find a Brushed Motor that would fit this job...since all are wound with heavy wire...and so, are amps hogs...plus heat galore...

Mine I got them from 12V Power Fans...battery operated...
