Rotor: Testing and Inspection

ROTOR CHECK




1. Check for continuity between the slip rings of the field coil. If the resistance value is not within the standard value, replace the rotor.

Standard value: approximately 2 - 5 ohms.




2. Check for continuity between the slip ring and the core. If there is continuity, replace the rotor.
