Non Oriented Electromagnetic Steel Sheet And Motor Core

Abstract: The present invention provides: a non-oriented electromagnetic steel sheet which has a chemical composition that contains, in mass%, 0.006% or less of C, 1.0% to 5.0% of Si, less than 2.5% of sol. Al, 3.0% or less of Mn, 0.30% or less of P, 0.010% or less of S, 0.010% or less of N, 0.10% or less of O and optionally another element, with the balance being made up of Fe and impurities, while having an average crystal grain size of 30 µm to 200 µm and a degree of integration of [111] <011> of 2.00 to 8.00 at a position corresponding to 1/4 the sheet thickness from the surface of the steel sheet in the sheet thickness direction; and a motor core which comprises this non-oriented electromagnetic steel sheet.
