Effects of temperature on mechanical performance of rotating electrical machinery

THE EFFECTS of temperature on electrical machinery are usually considered in connection with the deterioration of insulation used on the active conductors themselves. There are, however, many other parts of these machines where temperature effects are important and vitally affect the design of the machine. Unless provision is made in the design of machines to take care of these effects, unsatisfactory operation or reduced life may result. These effects on machine construction may be considered in three groups.
