14.1.2 Armature choke
When using Lenze 48XX/49XX controller adapted to the DC motor, it is not
necessary to use an armature choke.
When using other controller, check whether an armature choke will be required.
See Lenze Formula Reference.
An armature choke reduces
( the ripple content of the DC (lower thermal armature losses)
( the magnetic motor noises
( the torque harmonic waves for extremely high requirements to the
uniformity of the torque characteristic
( the brush wear.
Stop!
An additional inductance may cause a vibration of the drive. Please contact Lneze
before using an armature choke.
