Slot of electric machine

This is an example of the slot of electric machine simulation, performed with QuickField software.

Problem Type:
Plane problem of AC magnetics.

Geometry:

slot of electric machine model

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.

Solution:

Results:
Current density in slot of electric machine:
