Non-oriented silicon iron steels (NO FeSi) are produced and used in magnetic cores of the
electrical machines since several decades, because they are unexpensive materials and …

Due to worldwide regulations on electric motor manufacturing, the energy efficiency of these
devices has to be constantly improved. A solution may reside in the fact that high quality …

Nowadays it is very important to use non-oriented electrical alloys, which must have a very
good quality and must be cut through a proper method that leads to a minimum energy loss …

Punching and laser cutting of non-oriented silicon iron sheets (NO FeSi) determine changes
in the material at the cutting edge, which produce an important effect on the magnetic …

The magnetic cores of electrical machines are cut especially through mechanical methods
nowadays. In the zone near the cutting edge, a plastic deformation of the silicon iron steel …

In this paper the hysteresis energy losses in two non-oriented industrial steels (M400-65A
and M800-65A) were determined, by means of an efficient classical Preisach model, which …

Electrical motors are indispensable components in numerous large consumer goods, most
notably home appliances, besides electronic circuitry and mechanical parts. Their large …

The practical application of low energy loss steels and an optimal magnetic core design are
important, to minimize the energy losses in electrical machines. It is of great importance to …

The standard magnetic measurements, for grain oriented (GO) and non-oriented (NO)
electrical steels (FeSi), are made using the Epstein frame or the single strip tester. The …

The energy losses depend on the mechanical stresses, induced in the cutting process. It is
well known, that the electrical machine manufacturers want to minimize these effects and …
