1. Check the bearing for smooth rotation.
2. If it does not rotate smoothly, replace it.
Stator
1. Measure the resistance across each lead of the stator coil with an
ohmmeter.
2. If the measurement is not within factory specification, replace it.
3. Check the continuity across each stator coil lead and core with an
ohmmeter.
4. If infinity is not indicated, replace it.
Resistance
Rotor
1. Measure the resistance across the slip rings with an ohmmeter.
2. If the resistance is not the factory specification, replace it.
3. Check the continuity across the slip ring and core with an
ohmmeter.
4. If infinity is not indicated, replace it.
Resistance
Slip Ring
1. Check the slip ring for score.
2. If scored, correct with an emery paper or on a lathe.
3. Measure the O.D. of slip ring with vernier calipers.
4. If the measurement is less than the allowable limit, replace it.
