Abstract:
- The process of forming a mathematical model of an asynchronous motor as part of electric drives of hazardous industrial objects in an incomplete-phase emergency mode of operation, taking into account the fields of direct and negative sequence, which makes it possible to take into account the effect of an elliptical field in an incomplete-phase emergency modes of operation. The process of switching to the emergency two-phase operation mode is performed using the motor fault matrix. The results of simulation of transient processes in case of phase failure of the motor stator are presented. A comparison of the time diagrams obtained experimentally in terms of rotation frequency and current using an automated test bench and using a simulation model in the Matlab Simulink environment is performed. The adequacy of the proposed mathematical model is shown, which makes it possible to study an asynchronous electric motor in an emergency two-phase operation of a three-phase electric motor.
