Scientific reviewed journal "PROCEEDINGS. The Bulletin of Academy". Israeli independent academy of development of science, VOL. 16(1), p. 19-261565-7965https://elar.khmnu.edu.ua/handle/123456789/17315The paper analyzes the influence of unbalanced rotor forces of induction motor on the operation of bearings with clearances. A mathematical model considering mechanical unbalance and static magnetic unbalance is developed in the paper. The results of modeling showed that the joint action of these factors leads to unstable operation mode of bearings and accelerated wear. The unbalance factor depends on the static eccentricity angle and the instantaneous value of the trunnion rotation angle. The obtained results can be used to optimize the design of induction motors and to develop methods of diagnostics of their condition.enInduction MotorEccentricity of rotor massearing faultUnbalanced Magnetic PullСтаття621.313.333-192
