The construction of a computational digital model of an induction motor with ring windings (IMRW) for the processing of nuclear waste is considered. At the first stage of the work, the analysis of the overload capacity of the digital calculation model of IMRW was performed using the finite element method, while the calculation was carried out in stages, taking into account the technological and physical design features of the IMRW prototype. The IMRW model takes into account the influence of the oxide film of the stator core sheets, technological gaps, eddy currents and temperature conditions of the stator and rotor windings on the overload capacity of the IMRW. At the second stage, an analytical calculation of the mechanical characteristics of the IMRW was performed using the parameters of the substitution scheme determined by analyzing the design model of the engine in the Ansys program. The calculated mechanical characteristics of IMRW obtained by the finite element method and analytical calculation are compared with the test results of the first prototype.
