DC motor simulation

DC motor simulation, electric motor simulation, magnetic field inside electric motor

This example is prepared by Bozena Boreta and Jacek Sosnowski

Problem Type:
Plane-parallel problem of DC magnetics

Geometry of the DC motor:

Given:
The model of DC electric motor with permanent magnets you can analyze for:

• seven values of the steel yoke thickness s: 1 - 8 mm,
• three values of the current density j.

Solution:
The calculations are performed to investigate the mechanical torque (per 1 m depth) in the function of the yoke thickness and the current density (also other characteristics of materials). You can observe the saturation effect of the mechanical torque with the steel yoke growth and a deformation of the field lines with the current density growth. This information can be useful in a design process.

Results:
