Problem Type: Plane problem of AC magnetics. Geometry: All dimensions are in millimeters. Given: Relative permeability of air μ = 1; Relative permeability of steel μ = 1000; Conductivity of copper g = 58·106 Sm/m; Current I = 500 A; Frequency f = 50 Hz. Problem: In this tutorial we will analyze the skin effect occurring at the industrial frequency 50 Hz. The resistance of the conductor, carrying 500 A sinusoidal current, in the slot of the electric machine will be calculated. Results: Current density in slot of electric machine: Watch on YouTube.
