A good general guideline is for every 10 C above the maximum design temperature, motor life is cut in half. Let's say a Class F insulation motor is exposed to high ambient temperatures or has been over-loaded to the point that the internal motor temperature reaches 1650 C. If that motor would have lasted 20 years, it will now last 10 years.
Details
Furthermore, if we encounter a motor with insulation class F and a temperature rise of B, denoted as F/B, it signifies a temperature rise of 80°C + 40°C, summing up to 120°C. Comparing this with the maximum allowable temperature of 145°C, the motor exhibits a surplus of 145°C – 120°C, equating to 25°C.
