New electrical steel with high permeability

This article describes the magnetic properites of a low-silicon-bearing nonoriented electrical steel, recently developed by UGINE S.A. as a core material for rotating machines. The new product is characterized by a high level of permeability related to a partial ideal texture {100} < 0vw > . Typical properties are core losses of less than 5 W/kg at 1.5 T and 50 Hz and a magnetic polarization level > 1.78 T at 5000 A/m for a sheet thickness of 0.50 mm. The effects of sheet thickness and working induction on core loss at different frequencies are examined.
