Brush

Model considering voltage drop of carbon brushes

 Description The Brush component models the voltage drop and losses of carbon brushes. Note: The voltage drop $v$ is the total voltage drop of all series connected brushes. See also BrushParameters. If it is desired to neglect brush losses, set $V=0$ (this is the default).
 Equations $v=\left\{\begin{array}{cc}0& V\le 0\\ V& {I}_{\mathrm{linear}} $v={v}_{p}-{v}_{n}$ $i={i}_{p}=-{i}_{n}$ $\mathrm{lossPower}=vi$

Variables
