摘　　要：大功率船舶推进电机在运行时会产生磁场,该磁场会直接加大全船的磁场特征信号,本文通过对推进电机磁场的数字仿真研究,分析推进电机磁场的分布规律,评估推进电机磁场对船体磁场的影响。仿真表明推进电机磁场主要分布在垂直于电机轴的横向空间,且对船磁场的影响主要集中在推进电机正下方。When the high power ship propulsion motor operates,it will produce magnetic field which can directly make a superposition on ship magnetic field to increase the magnetic field characteristic signal of the whole ship.In this paper,through the digital simulation study on the ship propulsion motor,the distribution law of the propulsion motor magnetic field is analyzed and the effect of the propulsion motor magnetic field on the hull magnetic field is evaluated.The simulation results show that the strongest distribution region of the propulsion motor magnetic field is at the space perpendicular to the motor shaft,and that the region with the greatest influence on the hull magnetic field is right below the motor.
