PURPOSE: A non-oriented electrical steel sheet with excellent magnetic properties and a method for manufacturing the same are provided to increase the distribution density of coarse inclusions by properly managing the component ratios of allow elements, Al, Si, and Mn and impurity elements, N and S. CONSTITUTION: A non-oriented electrical steel sheet with excellent magnetic properties comprises Al of 1.0-3.0wt%, Si of 2.3-3.5wt%, Mn of 0.5-2.0wt%, N of 0.001-0.004wt%, S of 0.0005-0.004wt%, and Fe and impurities of the remaining amount, where the contents of Al, Mn, N, and S satisfy the following equations, {[Al]+[Mn]}Δ3.5, 0.002Δ{[N]+[S]}Δ0.006, and 300Δ{([Al]+[Mn])/([N]+[S])}Δ1,400. |
