Brush

Model considering voltage drop of carbon brushes

Information

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

Model of voltage drop and losses of carbon brushes. For currents between -ILinear and ILinear the voltage drop shows a linear behavior as depicted in Fig. 1. For positive currents greater or equal than ILinear the voltage drop equals V. For negative currents less or equal than -ILinear the voltage drop equals -V.

Note

The voltage drop v is the total voltage drop of all series connected brushes.
