Temperature and insulation life: why 10 extra degrees cost half

Short answer

Winding insulation ages with heat: every extra degree speeds up the reaction that makes it brittle. The industry rule says every 10 additional degrees cut insulation life in half. Blocked ventilation, dust on the fins, overload or unbalanced voltage add those degrees, and the damage doesn't come back.

Key points

Insulation ages with temperature, not voltage.
Every 10 extra degrees halve insulation life.
Blocked ventilation and dusty fins raise temperature.
Overload and unbalanced voltage add degrees too.
Heat damage does not recover.

How do 10 extra degrees take half the life of your motor? It's not the voltage, it's the temperature. Winding insulation ages with heat: every extra degree speeds up the reaction that makes it brittle. Like a rubber hose in the sun: it doesn't break the first day, but it cracks much sooner. The industry rule says every 10 additional degrees cut insulation life in half. But careful, blocked ventilation, dust on the fins, overload or unbalanced voltage add those degrees, and the damage doesn't come back. So it's not that the motor can take it, it's how much you're charging it. Does yours run hot? Comment TEMPERATURE and we'll tell you what to check.
