What is it about?
The need to reduce electricity consumption by electrical devices, including electric motors, is the reason for the development of new designs. In this paper a new rapid engineering method for the width estimation of the damaged material zone was presented, and the obtained result was compared with the results of other researchers, obtaining a high convergence.

Why is it important?
Currently, in mass production, motor cores are made of punched laminations—punching causes damage of core parts. For motors of relatively large geometrical sizes, this effect is ignored during design. For motors having small dimensions, this negative effect results in a reduction in efficiency, which is mostly small for this type of motor.
Perspectives
Writing this article was a real challenge for me, but I managed to link a large amount of practical research with simulation models.
