Flat magneto wire


I read somewhere here that there was some flat magneto wire, and I found a company in Mexico that actually makes it, here is what I found:

Is this usable for CD rom motor rebuilt?

mmm luis


the battery is flat in my translation glasses but if its a winding wire with a high dialectric coating see if you can get some samples with the same cross sectional area as the 23agw .56mm and thicker.

Should give more copper for a given area.

Morel still uses hexagonal wire in their voice coils. I built a couple of systems using their components almost 20 years ago and they had it then too, so there might be something to it if they're still doing it. The hexagonal shape packs so there is no air space.

It would be easier to use flat or hex wire in a part like a speaker voice coil than it would be in a motor winding. They are by nature much neater.
We tried flat wire at work for voice coils, but multi layer windings proved to be too tricky.
The wire in that case was just regular round wire that was passed through a pair of pinch rollers to squish it a bit.
We didn't try hex, but perhaps Morel has patents on that?
The other thing we sometimes use is aluminum wire. Has anyone ever tried it in motors to lower the weight?

pmackenzie, now that you mention it, aluminum is what Morel is using now days, be interesting to hear from the experts if there's a serious technical drawback to using aluminum on a motor, bet it's going to be heat.

Back in 1948 JBL pioneered the use of edge wound voice coils and provided us with the famous ''voice of the theatre'' series ,and killed the opposition for years,later on Lansing went his seperate way and became ''Altec'',''JBL'' still today make the best expontental drivers and intrument speakers.the flat wire is still regarded as the best way of getting the most copper into a given space as the wind is more easier controlled with no gaps but is not recomended for high turn counts as hot spots can develop that cause premature failure but is quite ok for 2or 3 layers in our application, the use of alluminium fails because of expansion due to heat wich distorts and fouls the magnetic gap in speakers according to my contact in this field.

Ecologito,

That's a very interesting idea and worth trying but wouldn't magnet wire with non-round (i.e. sharp) be very likely to create shorts?

If you look at the links on the first post, the wire seems to have two insulations coats that might prevent what you are talking about.

I emailed them and we'll see if I can get a sample of it.

You might be onto something. Especially if you take a look at Ron's
latest thread about multiple strands and coverage.

I also found this; no idea of minimum order.

Microsquare 1
Microsquare Magnet Wire

I'd tend to favor 130C polyurethane/nylon single coating for shorts (abrasion) resistance.

Note that the gauge is based on the rectangular dimension approximately equal to the circular diameter for that gauge, so resistance is roughly equal to round copper one gauge larger. (Round 23= 20.3 Ohms nom. /1,000 ft) The Microsquare 23 = 17.4 Ohms nom./1000 ft.)

They also have half gauge sizes in the round wire.

We have had good luck using rectangular magnet wire from www.alphacore.com/Flat%20Wire%20Shop/enter.html where I work. They will do a fairly small minimum order (still alot for CD-ROM type motors, but they sell 10 pound spools), and make it to your ordered size very quickly.

Flat magnet wire.


According to "David Theunissen", found on "flyelectric", there is no discenable advantage in using flat magnet wire.

I qoute:

"Flat wire.

Part of the challenge we face is because wire is round. By squashing some wire between a disc and my lathe's face plate I have been able to make some 'flat' wire. I had high expectations but found that because it is wider than round wire, the 'spiral effect' is greater and it wastes space at each end of the tooth. It also tries to stand up on its narrow end on subsequent layers, and this together with its propensity to twist results in no discenable advantange over round wire."
