copper loss

[′käp·ər ‚lȯs]
(electricity)
Power loss in a winding due to current flow through the resistance of the copper conductors. Also known as I 2 R loss.

4 shows that the fluctuation of winding copper loss is very large before the in-wheel motor operates at 26 ms, and the maximum amplitude is 110 W, but the fluctuations of the core loss and the eddy current loss of permanent magnet are low.
The major reasons are given: on the one hand, the copper loss of equivalent winding is located in the stator; on the other hand, stator iron core loss is more than rotor iron core loss and the eddy current loss of permanent magnet.
It achieves a high copper removal uniformity within and wafer to wafer with excellent end point detection resulting in total copper loss variation of less than +/- 150 angstroms.
The non-contact laser profiler performs quick, precise and direct measurements across the surface of the wafer to determine the amount of copper loss.
An expanded winding screen gives the user more per winding information such as current density, winding weight, IR drop and copper loss.
