Motor electromagnetic excitation force comparison in Maxwell 2D
Glad to join the community. I would be very grateful if someone can help me with this time.
I want to compare two motors' electromagnetic excitation (to evaluate motor's noise and vibration). I know we can compare the torque ripple and radial electromagnetic force(Please correct me if I am wrong).
But I don't know how to obtain the radial force in Maxwell 2D.
After some research in google, there may be three ways :
First one, force parameter way:select the stator and assign force in parameters before calculation. Then there will be a force_x and force_y in results. (But what's the meaning of this force? Can I use this force to obtain radial electromagnetic force? And how?)
Second one, maxwell stress tensor way: Define the formula in field calculator, then calculate the stator's radial force by integration along the stator's sideline.
Third one, edge force density way: select stator's sideline then assign edge force in field results. (What's the meaning of edge force density? How to use edge force density to compare two motor's electromagnetic excitation? What's the relationship of edge force density and parameter force?
