Standards for electrical steel sheets

Most of the time the electrical steel sheets are appointed as this way : M800-50A (E.U standard, BS EN 10106)

  • M : Magnetic
  • 800 : 8.00 W / kg (iron losses per kilogram) for B = 1.5T at the frequency of 50Hz
  • 50 : 0.50 mm (thickness of the iron sheet)
  • A : fully processed
