Research on thermal fault analysis of asynchronous motor based on simulation experiment

Abstract

With the continuous development of industrial society, electric energy has occupied almost all fields of life and production, which leads to the electric motor as its carrier playing an extremely important role in production life. Therefore, how to protect the motor and analyze its fault characteristics is of great practical significance. In this paper, by analyzing the structure and working principle of asynchronous motor, and combining the causes of thermal failure of asynchronous motor, the model of asynchronous motor under overload fault conditions is established, and MATLAB software is selected to further simulate and analyze the various states of the motor by changing its parameters. The final waveforms of the motor under different faults are obtained, aiming to promote the development of the field of thermal fault analysis and simulation of asynchronous motors in order to improve the stability of motor use.
