Analysis of Vibration Caused by Electromagnetic Force on Stator End-winding of Large Dry Submersible Motor
This paper investigates the vibration which caused by electromagnetic on the stator end-winding of the large dry submersible motor.Firstly,the electromagnetic field which included transition state and steady state is researched by 3-D FEM.Secondly,the electromagnetic force which lead to vibrations of end-winding is calculated by numerical method,it can be obtained that where endured the largest force density along the slant part of end-winding.Finally,the radial displacement and the axial displacement of the slant part which caused by vibrations is studied,the analysis results show that the axial displacement is larger than the amplitude of radial displacement.It indicates that the slant part of end-winding will be more easily damaged at axial direction than radial direction
