00:00:00.452 --> 00:00:01.869
Why can a large core test

2
00:00:01.884 --> 00:00:04.002
above its calculated
no-load loss?

3
00:00:04.842 --> 00:00:06.673
The steel grade
may be unchanged,

4
00:00:06.821 --> 00:00:08.278
but its stress
state can change

5
00:00:08.293 --> 00:00:09.212
during production.

6
00:00:10.077 --> 00:00:12.428
Uneven support
bends lower packets.

7
00:00:13.267 --> 00:00:15.358
Tilting redirects loads
through the frame,

8
00:00:15.493 --> 00:00:16.621
limbs and yokes.

9
00:00:17.472 --> 00:00:19.814
Uneven clamping can
concentrate pressure

10
00:00:19.829 --> 00:00:21.061
instead of spreading it.

11
00:00:21.926 --> 00:00:24.163
Grain-oriented steel
is sensitive to these

12
00:00:24.178 --> 00:00:25.475
mechanical stresses.

13
00:00:26.340 --> 00:00:27.884
Loss and noise can rise.

14
00:00:28.748 --> 00:00:30.387
Support the full
footprint on a

15
00:00:30.402 --> 00:00:31.725
rigid stacking table.

16
00:00:32.577 --> 00:00:34.515
Use a tilting
fixture that supports

17
00:00:34.530 --> 00:00:36.139
the core throughout
the movement.

18
00:00:36.991 --> 00:00:38.405
Check clamp-frame flatness,

19
00:00:38.540 --> 00:00:40.644
follow the specified
tightening sequence,

20
00:00:40.754 --> 00:00:41.582
and record it.

21
00:00:42.446 --> 00:00:44.007
Judge the finished
core with its

22
00:00:44.022 --> 00:00:46.286
agreed tests,
alongside the material

23
00:00:46.301 --> 00:00:47.090
certificate.
