This is an example of the slot of electric machine simulation, performed with QuickField software.
Plane problem of AC magnetics.
All dimensions are in millimeters.
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.
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.
Current density in slot of electric machine:
