Research fault of a squirrel cage ansynchronous motor1,5kW, 4 poles in the case of rotor-barsfailure

Abstract

In the paper, the research team analyses the rotor failures in squirrel cage rotor asynchronous motors.During the working process of the electric motor, various errors often occur, leading to the motor's failure, thereby stopping the operation and affecting the reliability and operation of the system. Faults that lead to motor failure, such as stator failure, rotor failure, and bearing failure. Among these faults, rotor failure due to rotor cracking that opens the rotor busbar is a common problem in motors with squirrel cage rotors. In the content of this paper, the authors use the finite element method and Ansys Electronics software application to study and analyse the performance of the 4-pole 1,5 kW asynchronous motor when the rotor fault occurs.
