00:00:00.452 --> 00:00:01.961
A round winding does not make

00:00:01.976 --> 00:00:03.338
the steel section round.

00:00:04.191 --> 00:00:06.650
Rectangular packets form steps inside the

00:00:06.665 --> 00:00:07.233
circle.

00:00:08.084 --> 00:00:09.238
With optimized widths,

00:00:09.360 --> 00:00:11.181
the article gives geometric fill of

00:00:11.196 --> 00:00:13.030
eighty-five point one percent for three

00:00:13.045 --> 00:00:14.967
steps, ninety point eight for five,

00:00:15.103 --> 00:00:16.946
and ninety-five point three for ten.

00:00:17.811 --> 00:00:19.970
These figures come before stacking factor

00:00:19.985 --> 00:00:21.048
and cooling ducts.

00:00:21.899 --> 00:00:23.213
More steps fill more of the

00:00:23.228 --> 00:00:25.283
circle, but each adds another strip

00:00:25.298 --> 00:00:26.986
width and another cutting setup.

00:00:27.850 --> 00:00:29.853
Narrow outer packets need good edges

00:00:29.868 --> 00:00:31.048
and secure clamping.

00:00:31.913 --> 00:00:33.603
Compare the steel section you need

00:00:33.618 --> 00:00:35.189
with the diameter available.

00:00:36.040 --> 00:00:37.588
Choose the step count together with

00:00:37.603 --> 00:00:40.075
cutting capability, cooling passages and

00:00:40.090 --> 00:00:41.322
assembly conditions.

00:00:42.173 --> 00:00:44.150
More steps alone do not establish

00:00:44.165 --> 00:00:45.058
a better core.
