PET insulation film
Problembeschreibung
PET film for motor insulation becomes brittle after high-temperature aging
Ursachenanalyse
The motor operating temperature is close to the upper temperature limit of PET; long-term thermal aging embrittles the film and causes loss of insulation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Lösung
For high-temperature motors, select hydrolysis-resistant and heat-resistant grades or switch to PEN film; verify service life according to insulation class temperature; after adjustment, continuously sample to verify the effect, and resume mass production only after confirming stability
Wichtigste Erkenntnis
Motor insulation film is selected according to temperature class; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a reference for troubleshooting similar problems in the future
