Abstract: The development of a computational model of an induction motor with ring windings (IMRWs) for processing of nuclear waste is considered. At the first stage of the work, the overload capacity of the computational model of an IMRW was analyzed using the finite element method, the calculation being carried out in stages, taking into account the production and physical features of the IMRW prototype design. The IMRW model takes into account the influence of the oxide film on 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, the mechanical characteristics of the IMRW were analytically calculated in the Ansys program using the parameters of the equivalent circuit determined by analyzing the design model of the motor. The calculated mechanical characteristics of an IMRW obtained by the finite element method and analytical calculation are compared with the results of testing the prototype. © Allerton Press, Inc. 2024.
