1) The commutating reactor in the field circuit is dimensioned for the rated motor field current.
2) The commutating reactor in the armature circuit is dimensioned for the rated motor current in the
armature. The line current equals DC current x 0.82.
3) The RI suppression filter for the armature circuit is dimensioned for the rated motor current in the
armature. The line current equals DC current x 0.82.
4) The RI suppression filter for the field circuit and the electronics power supply is dimensioned for the rated
motor field current plus 1 A.
5) The RI suppression filter for the electronics power supply is dimensioned for 2 A.
Note:
When RI suppression filters are used, commutating reactors are always required at the converter input to
decouple the snubber circuitry.
Commutating reactors are selected according to information in Catalog DA93.1.
