MAGNETIC CHARACTERISTICS OF NON-ORIENTED SILICON IRON STRIPS OBTAINED THROUGH MECHANICAL, LASER, ELECTRICAL DISCHARGE AND WATER JET CUTTING TECHNOLOGIES
Horia GAVRILĂ, Veronica MĂNESCU (PĂLTÂNEA), Gheorghe PĂLTÂNEA, Gheorghe SCUTARU, Ioan PETER
The increase of the asynchronous motors efficiency may be usually made by decreasing the total energy losses in the magnetic circuits. Non-oriented silicon iron (NO Fe-Si) sheets are soft magnetic materials with a nearly isotropic grain texture. They are used…
