Overview

Arrangement of the components for converter units
Arrangement of reactors and radio interference suppression filters
(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 armature current.
The line current is 0.82 times the DC current.
(3)
The radio interference suppression filter for the armature
circuit is dimensioned for the rated motor armature current.
The line current is 0.82 times the DC current.
(4)
The radio interference suppression filter for the field circuit is
dimensioned for the rated motor field current.
(5)
Radio interference suppression filters are not required for the
electronics power supply alone. Current consumption 1A at
400 V, 2 A at 230 V.
(6)
If the power supply voltages for the armature circuit, field
circuit and electronics power supply are the same, then the
voltage for the field and electronics power supply can also be
taken after the radio interference suppression filter for the
armature circuit.
