Information
This information is part of the Modelica Standard Library maintained by the Modelica Association.
Lets the user choose the layout, and determines the necessary DC current for DC current braking of an induction machine.
The icon shows the four layout variants. Phases with half the current are depicted with half the line thickness, phases with zero current are depicted with dashed line.
Parameters (6)
| INominal |
Value: 100 Type: Current (A) Description: Nominal RMS current per phase |
