Abstract :
Standard squirrel cage motors of moderate size have been studied to determine the protection against overheating secured by standard control devices. The results of these tests on the heating of motor windings and the temperatures at which control devices function, are presented herewith in a manner easy to follow and not complicated by the more highly theoretical considerations.
