For the analysis of motor fault between core plate

YR630-12 /1430 type of wound asynchronous motor stator core low excitation experiment was carried out

and failure under the same experimental conditions of magnetic flux density

current density distribution of a numerical simulation is performed and the eddy current loss. The results show that the simulation has good consistency with the experimental data

and the degree of fault

flux density

current density also increased accordingly. Electromagnetic field numerical simulation calculation can provide further basis for short-circuit fault analysis between slices

to verify the low excitation method between core plate to check short-circuit point between fault system by direct detection chip of fault current to find feasibility point of failure.
