Analysis of Typical Fault Mode and Research on the Fault Simulation Method for Motors
Fault injection test is an effective way to obtain data,and it is also a necessary link to realize online monitoring and fault diagnosis algorithm research and verification.The fault prototype is the basis of the fault injection test.Therefore,seven fault modes of motor stator twin-to-turn insulation failure,phase-to-phase short-circuit,phase grounding,rotor broken bar failure,bearing failure,rotor unbalance fault and eccentricity failure are studied.Firstly,the fault reasons and fault effects are analyzed.Then,the fault simulation methods of these fault modes are proposed,and the fault test is carried out by substituting the fault components and fault machine.Finally,taking an asynchronous motor as example,the concrete implementation method of the fault simulation is explained in detail,which has certain guiding significance for improving the reliability of motor.
