Loss comparison of non-oriented electrical steel materials to be used in PMSM under explosion protection aspects

The use and demand of the permanent magnetic synchronous machine (PMSM) is increasing in hazardous areas due to many advantages in the field of energy efficiency and easy controllability. The safe operation of the PMSM in potentially explosive atmospheric environments requires better understanding of non-oriented electrical steel sheet used for manufacturing in the rotor and stator yoke of the machine. This paper presents the comparison of non-oriented electrical steel of the same thickness but from a different manufacturing company.
