Information

This information is part of the Modelica Standard Library maintained by the Modelica Association.

Quasi-static model of a DC Machine with permanent magnets.
This model is fully compatible with the transient machine model of a DC machine with permanent magnets; the only difference is that electrical transients are neglected.
