3D-Analysis of a BLDC Motor

    • sandeepn20

      Hello everyone,

      I am facing a problem while doing a 3D analysis on a BLDC Motor. The back EMF reduces by 10 when converting 2D analysis to 3D. I use complete geometry, not a reduced one, for faster simulation. Is there any setting that I miss?

      Did you assign any mesh operations? By having a finer mesh, the simulation results will be more precise. Are the Losses equivalent in those two models? Core loss could affect significantly the back EMF. Could you please provide more information about the setup?
