Shaft seal failure allowing coolant or oil into the motor

Winding insulation breakdown or a phase-to-ground short after overheating
Connector pin damage at the power or feedback connector

Repair or replace?

ReplaceReplace the MPL-A310P-HJ72AA when the windings have failed or the frame or shaft is damaged. A matching MP-Series Motors Servo Drive bolts on with the same feedback and connectors, so check the full catalog suffix. A replacement MPL-A310P-HJ72AA is sourced on request, so compare its lead time with a repair before deciding.

RepairBearings, shaft seals, brakes and encoders are the usual faults on the MPL-A310P-HJ72AA and all are repairable while keeping the original feedback alignment. Repair is the better call when a matching motor is hard to source or when a matched set of axes must stay identical. Most MPL-A310P-HJ72AA units reach our bench with one of two symptoms: “Feedback (encoder / resolver) failure” or “Bearing wear”. Already swapped it out? Repairing the failed MPL-A310P-HJ72AA turns it into a tested spare on the shelf for the next failure. The MPL-A310P-HJ72AA repair is estimated $1,440.00, function-tested before return and covered by a 1-year warranty.
