DC, PMDC and Universal Motors

DC motors, PMDC motors and Universal motors have a field pattern that is approximately stationary. As eddy currents are unimportant Opera-2d/ST and Opera-3d/TOSCA are sufficient to calculate torque.

Opera-2d/ST and Opera-3d/TOSCA can be used to compute the torque at different current levels, including magnetic saturation, since eddy currents may be ignored in this instance. Cogging torque may also be computed using a snapshot approach using Opera-2d/ST and Opera-3d/TOSCA.

The rotating modules Opera-2d/RM and Opera-3d/CARMEN have options to include mechanical load and/or use variable speed operation and may be used to model eddy currents.
