Abstract :
In this paper, the current in the end ring of a submersible motor is studied by finite-element method. Since the resistance and the electromagnetic force of end ring are related to its current, it is essential to study the current distributed characteristics in detail. Based on the Maxwell´s equations and equivalent circuits, the final current density in the end ring is calculated. Then, the characteristics of end-ring current distribution are compared in the same cross section, as well as those of different cross sections along circumferential direction. Finally, the effects of the radical width and axial width of end ring on its current distribution are investigated.
