摘要
空心补偿脉冲发电机励磁绕组采用同心式结构,该电机气隙磁场的计算需要采用场的方法。文中采用两种解析方法和一种数值方法对一台空心脉冲发电机的气隙磁场进行了计算。其中,解析方法包括一种基于平行双导线磁场计算原理和叠加原理的二维方法,另一种是基于平面矩形线圈磁场计算方法和叠加原理的三维方法。数值方法是采用ANSYS有限元计算软件,对电机磁场分布进行计算和绘图。本文提供了三种空心电机磁场的计算方法,得到了磁场分布图和解析表达式。
In this paper, three methods are used to calculate the magnetic field of an air-core compulsator, which are two analysis methods and a finite-element method One of the analysis methods is based On the parallel two-conductor line electromagnetic theory and the superpoSition principle. The other is a three-dimensional way that uses square coil electromagnetic theory and the superposition principle to calculate magnetic field The finite-element method, based on the software ANSYS, calculates and plots the magnetic field distribution of compulsator.
