电机分布电容参数的精确仿真计算及实际测定
Accurate Simulation Calculation and Actual Measurement of Distributed Capacitance Parameters of Motor
摘要
Abstract
The common-mode equivalent circuit model of the motor is the basis for analyzing the electric erosion of bearings,especially for analyzing the technical problems and experimental phenomena of shaft voltage and shaft current,among which the centralized equivalent model is an important calculation basis for the key index of bearing electric erosion that is bearing voltage ratio(BVR),which can be evaluated in the early stage of motor design.The accurate simulation calculation of the distributed capacitance parameters of the centralized equivalent model were studied in depth.Firstly,the simulation calculation and comparison of the two-dimensional single-slot and full-model motors were carried out.Secondly,the influence of the stator winding end and the rotor end ring on the stray capacitance was considered,and the three-dimensional motor model was simulated and calculated,and the more accurate distributed capacitance parameters were obtained through comparative study.Finally,the parameters of YQ190-14 type traction motor were taken as an example,and the simulation calculation results and test results were compared and analyzed,and the accuracy of the simulation calculation results was verified.关键词
