Windings vs. Diameter
Original poster: Vardan <vardan01@xxxxxxxxxxxxxxxxxxxxxxx>
Hi,
Just for the record...
The coil I just wound:
http://drsstc.com/~sisg/files/SISG-coil/P6290127.JPG
is 11.50 long with #30 wire. There are 985.00 turns on it via digital counter.
The wire is 0.0116 inches in diameter via a new Starrett 436 micrometer.
985 x 0.0116 = 11.426 inches. Pretty close ;-)) I pushed the wire
with a finger nail all the way during the wind so it is tight and the
wire torque was high. The wire is "cheap" and had a few rough spots
I could feel as it was going out my fingers.
There is a "wiring percentage" number of 91% for this wire that seems
all wrong...
If you can measure the wire diameter really well and wind it tight
and forced, the "wire diameter x turns" seems to work out just
fine... Thin wire like this forces more easily than thicker...
Cheers,
Terry
