Inputs

Brush input parameters

Two definition modes can be chosen for brushes
  • Auto: Brushes dimensions and angular position are automatically calculated by FluxMotor to get the best fit with the defined winding. No input needed.
  • User: Brushes dimensions and angular position are defined by the user.

The table below contains the brush input and their default values for “auto” mode.

Label Tooltip, note Default value (auto mode)
Nº of brushes Number of brushes. Only unblocked for wave winding Number of poles
Angular position Angular position of the reference brush (polarity +)

Center of a north pole (for lap winding)

Center of a south pole (for wave winding)

Pitch angle Pitch angle of a brush 0.85 times the segment commutator pitch for simplex winding (1.85 for duplex and 2.85 for triplex)




Commutator – Brush definition mode: None Commutator – Brush definition mode


Angles are illustrated in the visualization
1 Select a parameter highlights it.
2 Select a parameter label displays the corresponding angle on the picture.
3 Select a parameter displays the corresponding tooltip which provides additional information
