Information

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.

If it is desired to neglect brush losses, set brushParameters.V = 0 (this is the default).
