Non Oriented Electrical Steel Sheet, Motor Core And Motor

Abstract: This non-oriented electrical steel sheet has a composition that may undergo an a-? transformation. The composition contains 0.3% to 0.7% of sol. Al and 0.0005% to 0.0020% of Ti, with the contents of Si, Mn and sol. Al satisfying a specific relationship. When the surface of the steel sheet is measured using a scanning electronic microscope with electron backscattered diffraction (SEM-EBSD), if the area ratio of crystal grains in a \{hkl\} orientation (with a tolerance within 10°) with respect to the entire field of view is represented by Ahkl-uvw, A411-011 is 15% or more, and the number density of precipitates is 0.0001 per µm2 to 0.3000 per µm2.
