Abstract

In some cases, laser fusion cutting of non-oriented electrical steel laminations for electrical machines has been investigated for some years but with unsatisfactory success. Certainly, recent laser beam technology seems to be a promising step forward, and opens up the manufacturer to new fields of application. In this paper, laser cutting of electrical sheet metal applying various beam sources with regard to the magnetic property deterioration is compared with conventionally manufactured samples. The obvious correlation of wavelength and affected magnetic parameters is characterized by using a commercialized measurement system. Moreover, an overview about the origin of the deterioration participating effects is given.
