Research on stator winding fault simulation model of induction motor

induction motors;  stator winding failure;  Modeling

Each parallel branch of the stator side winding of the induction motor is regarded as a branch, and the rotor side is equivalent to two windings perpendicular to each other of the D axis and the Q axis, and the flux linkage equation and voltage equation of the induction motor based on the parallel branch of the winding are established. According to the voltage equation and flux equation of the branch after the fault, the equivalent analog circuit of various winding short-circuit faults is obtained. For a winding breakage fault, the impedance of the winding can be simulated as a considerable number, and finally a 45 kW motor parameter can be simulated.
