Check cooling
Dust on fins, a failed fan or blocked ducts raise temperature.

Why an injection moulding servo pump motor overheats
Overheating usually comes from winding or bearing wear, blocked cooling, a high constant load or a drive setting problem. Stop the machine if the motor is too hot to touch, check airflow and cables, then send the nameplate photo for diagnosis.
01Guide
Servo motor overheating
Check bearings
Noise or shaft play points to bearing wear.
Check windings
Winding insulation faults need a bench test, not a guess.
Check the drive
Overload settings and current limits can cause constant high load.
