PPO Rotor and Housing Parts
Problem Phenomenon
[Problem Phenomenon] Material selection for motor rotors, housings and transformer parts
Cause Analysis
PPO is suitable for electrical parts of motors, rotors, housings and transformers: heat resistance, insulation and dimensional stability; performance retention in the temperature-rise environment of long-term operation; during on-site troubleshooting, verify item by item according to this mechanism, and avoid blindly adjusting the machine based only on experience
Solution
Select heat-resistant PPO grades for motor parts; match the insulation system according to the temperature class; check fatigue under operating vibration; after adjustment, take continuous samples to verify the effect, and resume mass production only after confirming stability
Key Takeaway
PPO for motor rotors and housings has stable performance in temperature-rise environments; after confirming effectiveness, solidify 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
