Electromechanical relays have a coil of wire with a rod passing through the middle ( forming an electromagnet ) , an armature mechanism , and one or more sets of contacts 机电式继电器有一个中间穿过一根金属棒的线圈（形成一个电磁铁） 、一个枢轴机构和一组或多组触点组成。
The cutter has high reliable cylinder and proportional electro - magnet for force , and the tools lift and down all controlled by computer so that the system has good stable 切刀装置采用高可靠性的汽缸和比例电磁铁加压，以保证系统稳定，抬落刀过程均由计算机控制，准确可靠
Whin the power is off , the electromagnet loses electromagnetic force . the armature is pushed by the spring and sticks to endshield of the motor immediately , the rotation is stopped therefor 当电机失电时电磁铁失电，衔铁立即被弹簧顶住，使制动盘与电机后端盖压合在一起，停止转动。
The experiments of lim and electromagnet can be executedon computer automatically . the tests and analysis have showed that the measure and control system has high accuracy and reliability 直线电机与电磁铁的试验可以在计算机上自动完成，试验与分析结果表明整个测控系统具有较高的精度与可靠性。
The dc draining electromagnet zdt series is the main accessory for the household full - auto washers and acts as openingclosing the drainage valve when working after being rectified with a diode bridge rectifier 直流排水电磁铁zdt系列是家用全自动洗衣机主要配件，经二级管桥式整流后工作，主要起打开关闭排水阀作用。
Abstract taking the electric control sircuit of the flanging machine as an example , this single electromagnet directional control calce is used to design the electric control circuit with several sequential cylinders 摘要本文以卷边机电气控制回路设计为例子来说明使用单电磁铁换向阀进行多气缸顺序动作电气控制回路的设计方法。
The effect of economizing energy and materials after the contactor adapts the electro - ecomonizer and its reliability is useful to the research on operating - control and economizing electricity of other electromagnets 接触器配用节电器后的节能、节材效果显著，节电器工作可靠，可供其他电磁铁的操作控制及节电研究参考，具有一定的实用价值。
The connections and characteristics of electric current , force and displacement of the proportion electromagnetism had been studied and tested . in the meantime , the proportion controller of the electromagnetism had been improved 再对比例电磁铁的电流、力和位移三者之间关系和特点进行了试验研究，同时对其控制器电子比例控制器进行了改进。
The electricity fitting according to program of the hydraulic system then choices the work way , refers in the discovery news leads make the electromagnet work in order to finish the stipulation the craft operating cycle 电气装置按照液压系统规定的动作程序，选择规定的工作方式，在发现讯件的指领下，使有关的电磁铁动作以完成规定的工艺动作循环。
