摘　　要：CINRAD/SA天气雷达投入业务运行以来,在天线伺服系统方面出现了很多次故障,而直流方位电机是天线伺服系统的主要组成部分也是发生故障较多的部件之一。2014年福建长乐CINRAD/SA天气雷达在重大天气保障过程中,连续发生方位电机卡死造成雷达停机和测速机性能降低引起天线转速不稳造成雷达产品异常的故障;根据天线控制信号流程,通过运行雷达RDASOT测试程序、测量直流方位电机阻值、测量测速机反馈电压等方法,分析其故障的成因,对雷达伺服直流电机故障分析及解决方法有重要的指导作用。There occurred many faults in the antenna servo systems since CINRAD/SA put into operation.As the main part of the antenna servo system,the DC azimuth motor is also one of components with frequent faults.A continuous locking fault occurred in DC azimuth motor at Changle radar station in 2014,leading to radar shutdown and tachometer performance degradation,in which the instability of antenna rotational speed resulted in abnormal PUPC in the process of major weather guarantee.The causes of the problem are analyzed by using the test program RDASOT（radar data acquisition system operability）,measuring the resistance of the DC azimuth motor,and the feedback voltage of the tachometer according to the controlling process of antenna signals.The results are useful for the maintenance and operation of radar DC motors.
