DC Motor Testing from the Motor
The AT7P offers the following configurations for testing DC motors directly at the DC Motor.
Testing directly from motor provides a more detailed and in-depth analysis, since the different
motor fields can be measured at the motor and a DF & Cap tests can be performed at the motor.
The following configurations for testing directly at the DC motor are available:
DC Series Motors
DC series motors have the field and armature
windings connected in series. When testing DC
series motors at the motor series field windings
and armature windings can be measured
separately.
The armature leads are normally labeled A1 & A2; the filed leads are normally labeled S1 & S2.
Note: Always remeasure the armature windings to look for carbon build up.
Testing the DC motor locally provides the option of performing a DF & Cap to ground test.
Additionally, it is also possible to take IRG measurements on the individual field and armature
windings.
INS1 = field windings to ground
INS2 = armature windings to ground
STATIC readings for DC Series Motors
