DC Motors Testing
Disconnect the motor from the line. To test the brush rigging, eld coils
and armature connect one lead to the grounded motor housing and
the
other lead to the brush on the commutator. If the resistance measure
ment
indicates a weakness, raise the brushes off the commutator and
separately test the armature, eld coils and brush rigging by connecting
one lead to each of them individually, leaving the other connected to the
grounded motor housing. The above also applies to DC Generators.
