摘　　要：分析了在消旋伺服控制系统中,电机与感应同步器轴连时,调宽波驱动的电机电枢交变磁场对感应同步器输出产生干扰的机理,提出了在电机靠近感应同步器一端加屏蔽层,并提高调宽波频率,以使电磁干扰减到最小。实验表明,该方法有效地抑制了由调宽波引起的电磁干扰,为保证消弦控制系统的正常工作创造了条件。The mechanism is analyzed that of the interference on the signal output of the inductorsyn from the engine armature's alternate changing magnetic field in the despun control system when the engine is connected with the inductorsyn through the axes.Solutions have been brought forward that the frequency of the pulse width modified wave excerted on the moment engine is improved and a metalline piece of shield is added at the end of the moment engine nearer to the inductorsyn,in order to deduce the interference from the engine's magnetic field.The experiment shows that the methods restrain the interference of the magnetic field brought by the pulse width modified wave,and so the good conditions are created for the system to work normally. 
