Based on the working principle of gyro spin system,the magnetic characteristics curve of the modulating coil was analyzed,and the possibility of some positions that fail to start of gyro rotator are pointed out theoretically,then the concept of excitation current equivalent of magnetic field was put in this paper.
从某型导弹陀螺旋转系统的旋转工作原理出发,分析了调制线圈的磁特性曲线,从理论上指出了陀螺转子存在启动死区的可能性,引入了磁钢磁场等效激磁电流当量的概念,并给出了解决该问题的途径。
