The paper presents a complete variable structure mathematical model of the temperature fields inside stators and rotors of rotational electric machines that work in different modes, including the interrupted work with different relationship between the work and the rest time, and taking into account the change of temperatures of the air that circulates in the air gap. The algorithm developed mainly for a case of two - material cylindrical wall of simple geometry can also take into account different geometry of the stator and rotor. The results of investigations of temperature fields are also presented to determine the influence of the temperature changes in the air gap on the maximum temperatures inside stators and rotors. These investigations aim at establishing the optimal design of cooling systems for rotational electric machines.
