ABSTRACT

Purpose – analysis of the reliability of induction motors in unstable voltage supply by predicting the thermal state of the induction motor.

The object of investigation: asynchronous motor with squirrel-cage rotor.

The subject of investigation: the thermal characteristics of induction motor in long-term modes in instability voltage.

The analysis of the influence of the supply voltage is conducted distribution of losses at the nodes of asynchronous motor with squirrel cage motor that allow explore the temperature field of induction motor in the long-term modes at different voltages and loads.

At the analysis of the thermal state of the induction motor installed effect of

changes in voltage on the temperature field of induction motor at constant torque on

the shaft and DC stator.
