Overheating Electric Motors: A Major Cause of Failure

2019-8-28 · As an example, if a motor that would normally last 20 years in regular service is running 40 C above rated temperature, the motor would have a life of about 1 year. Leading standardization organizations have concluded that 30 percent of motor failures are attributed to insulation failure and 60 percent of these are caused by overheating.

What Causes a Computer to Overheat? Sciencing

What Causes a Computer to Overheat? Poor ventilation can also be a significant cause of overheating. Most computer cases have vents that allow the passage of air into and out of the casing. If these vents are covered due to the location of the computer, dust accumulation or other reasons, this critical airflow is stopped and warm air will
