Life of an engine

An electric motor of class A will have a limit temperature of 1050ºC, but if it operates at a temperature of 900ºC, it will have a life expectancy of up to 26 years. If its operating temperature is 1000 ° C, the utility expectation will be reduced by half and if it reaches 1500 C, it would be only 48 days. https://www.mrosupply.com/page/mrosupply-coupon-codes/ The life expectancy of an engine is the life expectancy of its winding.

The life of an engine ends when a fault occurs in its insulation because the cost of winding represents about 50% of the cost of the engine. The deterioration of the insulation of the coils forming the winding will depend on the temperature it is subjected to during operation and the external destructive effects such as vapors, chemicals, moisture, dust and other abrasives in contact with the insulation. The useful life expectancy of an engine varies widely with the expected service conditions for it and may be 500 to 1000 hours for certain aeronautical and electronic equipment or 20 to 30 years for some industrial engines. In many cases it can be established that the deterioration rate of the insulation is an exponential function of temperature.
