摘要
就磁转速表活动系统的动态特性以及在附加交变力矩的作用下，指针摆动随转速变化的规律，从理论上进行了分析，并结合实际探讨了指针摆动的故障原因。
This paper treats of the transient characteristics of the magnetic tachometer's working system and theoretically analyses the law of how the pointer vacillates with the tachometric variation under the work of an extra alternating torque. In addition, it analyses the cause of the pointer vacillation failures on the basis of pratice.
