水下航行器用永磁直流电机漏磁场数值分析

摘要

Based on the Magnet software, a leakage magnetic flux of a permanent magnet DC motor for the propulsion of a certain underwater vehicle is numerically simulated by a finite element method, and the numerical relation between the leakage magnetic strength and the distance of the DC motor is obtained. Furthermore,a good method is presented to analyze a disadvantageous influence of the leakage magnetic flux of a permanent magnet DC motor for the propulsion of underwater vehicles to their nearby electronic instruments and equipments.%基于Magnet软件,对某型水下航行器推进用永磁直流电机漏磁场进行了有限元数值仿真,得到了电机漏磁场强度与电机距离之间的数值关系,也为分析水下航行器推进电机漏磁场对其附近电子仪器设备带来的不利影响,提出了一个良好的方法.
