• The three main materials used to build IMs are of magnetic, electric, and insulation type.
• As the IM is an a.c. machine, reducing eddy current losses in its magnetic core is paramount.
• It is shown that these losses increase with the soft magnetic sheet thickness parallel to the external a.c. field.
• Soft magnetic materials (silicon steel) used in thin laminations (0.5 mm thick up to 200Hz) have low hysteresis and eddy current losses (about or less 2 W/kg at 1 T and 60 Hz).
• Besides losses, the B-H (magnetization) curve characterizes a soft magnetic material.
