Rotor: Testing and Inspection

Rotor

-

Using ohmmeter, check for continuity between slip rings of rotor. If there is no continuity, replace rotor.

Resistance between slip rings of rotor Standard: 1.6 - 2.0 Ohm at 20 °C (68 °F)

-

Using ohmmeter, check that there is no continuity between slip ring and rotor. If there is continuity, replace rotor.

-

Check slip rings for roughness or scoring. If rough or scored, replace rotor.
Using a vernier caliper, measure the slip ring diameter.
If the diameter is less than minimum, replace the rotor.

Diameter of slip ring
Standard: 14.2 - 14.4 mm (0.557 - 0.567 in.)

Diameter of slip ring 
Minimum: 12.8 mm (0.504 in.)
