FIELD: mechanical engineering.
SUBSTANCE: method can be used in development of new technologies for creation of short-circuited rotors of electric machines and experimental determination of their operational reliability. Method for thermal cyclic testing of a workpiece for an electrotechnical part contains a permanent interface connection "copper conductive material-magnetic steel" includes the stages of installation in the workpiece of the measuring system consisting of the group of thermocouples, arrangement and fixation of the workpiece, performance of the specified number of thermal cycles, collection of the obtained experimental data.
EFFECT: obtaining reliable indicators of resistance to cyclic thermal loads, increasing service life and operational reliability of electric machine.
