| | Incremental motion encoder (IME) is a new type of transducer for shaft center trace measurement with resolution up to sub-micro. It not only has wide measuring range and high precision but is not affected by the property of a measuring system and not interfered by electromagnetic noise because it is a typical digital transducer without analogous amplification and filter. It combines both functions of torsion sensor and shaft center position sensor in one and has wide application prospects in the field of be... | | 运动增量编码器(IME)是一种新型的轴心轨迹测量传感器,其测量灵敏度可以达到亚微米级.它是典型的数字化传感器,没有模拟放大和滤波等环节,量程很宽且测量精度不受系统特性的影响和噪声干扰,这种传感器在测取轴心轨迹的同时还能获得轴的扭振信号,实现了两种传感功能的集成.在轴承及转子故障诊断和回转运动精度分析中有广泛的应用前景.提出了IME测量过程中的“角增量”概念,并以此分析了IME的测量原理和误差来源,在此基础上提出了无偏差系统的方法原理. | | 文摘来源 | | It's very important that accurate position of the edge of start stop shear to high speed wire mill production.Shear would run by accurate controlled.The article expound a kind of position control system that is made up of high speed pulses counter,PLC and light cell code device. | | 剪刃位置控制是高速线材生产中所使用的启停式飞剪的关键控制环节 ,其控制精度的高低直接影响到飞剪的正常工作。文章介绍的是采用由高速脉冲计数器、PL C和光电增量编码器构成的位置环控制系统。 | | 文摘来源 | | This paper introduces a type of circuit which can digitize signal of inductosyn by AD2S90.
