| Abstract | The paper justifies the need to monitor and control the thermal state of the induction motor as a whole and its windings, as the most heat-loaded elements. A review of modern methods of measuring and determining the temperature of windings (including rotating) is carried out. It showed trends in the use of non-contact methods for determining temperature using mathematical models based on the finite element method and relevant thermal equivalent circuits. To determine the temperature distribution, an equivalent thermal model of an induction motor, consisting of 53 nodes, 31 of which are heat generating was developed. To determine the losses, a T-shaped equivalent circuit for replacing motor windings was used, taking into account losses in steel, non-linearity of the magnetization curve and the effect of current displacement in the rotor winding. The simulation results in steady and transient modes are presented. |
