电磁致动器及其监视
摘要：
一种组件包括电磁致动器（80）和电压响应装置（26），使得致动器内衔铁（1）的位置能够被监视。致动器包括两个线圈（4），串联连接在一起，所述衔铁通过使电流脉冲通过所述线圈，在至少两个磁性锁定的稳定静止位置之间可切换，以及输出接触器（82），电气连接到线圈之间的接头（24），以便对接头处的电压进行监视。电压响应装置（26）电气连接到输出接触器（82），以便在电流脉冲通过线圈（4）时，响应在所述输出接触器上产生的电压，提供输出信号，给出衔铁（1）位置的指示。也提供了监视衔铁位置的方法。
摘要（英）：

An assembly includes an electromagnetic actuator (80) and a voltage response arrangement (26) to enable the position of the armature (1) within the actuator to be monitored. The actuator includes two coils (4) joined together in series, the armature being switchable between at least two magnetically latched stable rest positions by passing a current pulse through the coils, and an output contact (82) electrically coupled to the junction (24) between the coils to facilitate monitoring of the voltage at the junction. The voltage response arrangement (26) is electrically coupled to the output contact (82) so as to provide an output signal giving an indication of the position of the armature (1) in response to the voltage generated on the output contact when a current pulse is passed through the coils (4). A method of monitoring the armature position is also provided.
