B&R 8LSA46.RO045DO00-0伺服电机可使控制速度，位置精度非常准确，可以将电压信号转化为转矩和转速以驱动控制对象。伺服电机转子转速受输入信号控制，并能快速反应，在自动控制系统中，用作执行元件，且具有机电时间常数小、线性度高、始动电压等特性，可把所收到的电信号转换成电动机轴上的角位移或角速度输出。分为直流和交流伺服电动机两大类，其主要特点是，当信号电压为零时无自转现象，转速随着转矩的增加而匀速下降。有刷电机成本低，结构简单，启动转矩大，调速范围宽，控制容易，需要维护，但维护不方便换碳刷，产生电磁干扰，对环境有要求。因此它可以用于对成本敏感的普通工业和民用场合。

同步电机，极对数:5对，标称速度:300O rpm失速扭矩:10.000 Nm，无制动器，光滑轴，倾斜连接器旋转，中心直径95 mm, j6 fit(冷却，A型结构，IP64防护，无油封560 vDC，制动器保持扭矩:0.00 Nm，EB ind。32线多圈V2。伺服系统是使物体的位置、方位、状态等输出被控量能够跟随输入目标或给定值的任意变化的自动控制系统。伺服主要靠脉冲来定位，基本上可以这样理解，伺服电机接收到1个脉冲，就会旋转1个脉冲对应的角度，从而实现位移，因为，伺服电机本身具备发出脉冲的功能，所以伺服电机每旋转一个角度，都会发出对应数量的脉冲，这样，和伺服电机接受的脉冲形成了呼应，或者叫闭环，如此一来，系统就会知道发了多少脉冲给伺服电机，同时又收了多少脉冲回来，这样，就能够很精确的控制电机的转动，从而实现精确的定位，可以达到0.001mm。直流伺服电机分为有刷和无刷电机。

B&R 8LSA46.RO045DO00-0 servo motor can control speed and position accuracy very accurately, and can convert voltage signals into torque and speed to drive the control object. The rotor speed of a servo motor is controlled by input signals and can react quickly. In automatic control systems, it is used as an executing element and has characteristics such as small electromechanical time constant, high linearity, and starting voltage. It can convert the received electrical signal into angular displacement or angular velocity output on the motor shaft. It is divided into two categories: DC and AC servo motors, and its main feature is that there is no self rotation phenomenon when the signal voltage is zero, and the speed decreases uniformly with the increase of torque. Brushed motors have low cost, simple structure, large starting torque, wide speed range, easy control, and require maintenance. However, maintenance is not convenient to replace carbon brushes, resulting in electromagnetic interference and environmental requirements. Therefore, it can be used in cost sensitive general industrial and civil applications.

Synchronous motor, 5 pairs of pole pairs, nominal speed: 300O rpm, stall torque: 10.000 Nm, without brake, smooth shaft, tilting connector rotation, center diameter 95 mm, J6 fit (Cooling, A-type structure, IP64 protection, no oil seal 560 vDC, brake holding torque: 0.00 Nm, EB ind. 32 wire multi turn V2. The servo system is an automatic control system that allows the output controlled variables of the object’s position, orientation, state, etc. to follow any changes in the input target or given value. The servo mainly relies on pulses for positioning, which can be basically understood as follows: when the servo motor receives one pulse, it will rotate the angle corresponding to one pulse, thus To achieve displacement, because the servo motor itself has the function of emitting pulses, it emits a corresponding number of pulses every time the servo motor rotates at an angle. This corresponds to the pulses received by the servo motor, or a closed loop. In this way, the system will know how many pulses have been sent to the servo motor and how many pulses have been received back. This allows for precise control of the motor’s rotation, Thus achieving precise positioning, which can reach 0.001mm. DC servo motors are divided into brush and brushless motors

PLC控制器本身的硬件采用积木式结构，各厂家产品结构大同小异。以日本欧姆龙C200HE为例，为总线模板框式结构，基本框架(CPU母板)上装有CPU模板，其它槽位装有I/O模板;如果I/O模板多时，可由CPU母板经I/O扩展电缆连接I/O扩展母板，在其上装I/O模板;另一种方法是配备远程I/O从站等。这些都说明了PLC厂家将硬件各部件均向用户开发，便于用户选用，配置成规模不等的PLC，而且这种硬件配置的开放性，为制造商、分销商(代理商)、系统集成商、最终用户带来很多方便，为营销供应链带来很大便利，这是一大成功经验。
