附录A
Power motor for EPS provide the power, the power source of the system is EPS, according to the instructions of the unit, and the output ECU for the aid of torque. Power motor performance in largely decided to the EPS system performance, so EPS system to motor performance requirements of the high. Compared to normal motor, electric power steering system with the motor should have the following characteristics. First of all because most vehicle power supply for 12 V dc, therefore, ask dc motor power supply electricity down and have big rated current of the rated power; and Secondly, the volume as low as possible, inertia, wide range of speed regulation of small, control characteristic, smooth operation, and low torque fluctuation little, low speed. High speed, big gear ratio will increase of mechanical system, the influence of system dynamic performance inertia; In turn blocking when can also provide power torque. For large vehicles, or even should be able to provide the opposite direction of power and rotational torque.
附录B
助力电机为EPS提供动力，是EPS系统的动力源，它根据ECU单元的指令，输出适宜的助力转矩。助力电机的性能在很大程度上便决定了整个EPS系统的性能，因此EPS系统对电动机的性能要求很高。相对普通电动机，电动助力转向系统用电机应该具有以下特点。首先由于绝大多数车载电源为12V直流，因此要求直流电机供电电压低，并且具有大的额定电流和额定功率;其次，体积尽量小，转动惯量小，宽广的调速范围，控制特性好，低速运行平稳，力矩波动小，转速低。高转速下，大的齿轮传动比将会增加系统的机械惯量，影响系统动态性能;在堵转时也能提供助力转矩。对于大型车辆，甚至应该能够提供与转动方向相反的助力转矩。

Inventory management Inventory Control On the so-called "inventory control", many people will interpret it as a "storage management", which is actually a big distortion. The traditional narrow view, mainly for warehouse inventory control of materials for inventory, data processing, storage, distribution, etc., through the implementation of anti-corrosion, temperature and humidity control means, to make the custody of the physical inventory to maintain optimum purposes. This is just a form of inventory control, or can be defined as the physical inventory control. How, then, from a broad perspective to understand inventory control? Inventory control should be related to the company's financial and operational objectives, in particular operating cash flow by optimizing the entire demand and supply chain management processes (DSCM), a reasonable set of ERP control strategy, and supported by appropriate information processing tools, tools to achieved in ensuring the timely delivery of the premise, as far as possible to reduce inventory levels, reducing inventory and obsolescence, the risk of devaluation. In this sense, the physical inventory control to achieve financial goals is just a means to control the entire inventory or just a necessary part; from the perspective of organizational functions, physical inventory control, warehouse management is mainly the responsibility of The broad inventory control is the demand and supply chain management, and the whole company's responsibility. Why until now many people's understanding of inventory control, limited physical inventory control? The following two reasons can not be ignored: First, our enterprises do not attach importance to inventory control. Especially those who benefit relatively good business, as long as there is money on the few people to consider the problem of inventory turnover. Inventory control is simply interpreted as warehouse management, unless the time to spend money, it may have been to see the inventory problem, and see the results are often very simple procurement to buy more, or did not do warehouse departments . Second, ERP misleading. Invoicing software is simple audacity to call it ERP, companies on their so-called ERP can reduce the number of inventory, inventory control, seems to rely on their small software can get. Even as SAP, BAAN ERP world, the field of

伺服电机 1. 伺服电机的定义 伺服电动机又称执行电动机，在自动控制系统中，用作执行元件，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。伺服电机在伺服系统中控制机械元件运转的发动机. 是一种补助马达间接变速装置。伺服电机可使控制速度, 位置精度非常准确。将电压信号转化为转矩和转速以驱动控制对象。转子转速受输入信号控制，并能快速反应，在自动控制系统中作执行元件，且具有机电时间常数小、线性度高、始动电压低等特点。 2. 伺服电机工作原理 1.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，但维护方便（换碳刷），产生电磁干扰，对环境有要求。无刷电机体积小，重量轻，出力大，响应快，速度高，惯量小，转动平滑，力矩稳定。控制复杂，容易实现智能化，其电子换相方式灵活，可以方波换相或正弦波换相。电机免维护，效率很高，运行温度低，电磁辐射很小，长寿命，可用于各种环境。 2. 交流伺服电机也是无刷电机，分为同步和异步电机，目前运动控制中一般都用同步电机，它的功率范围大，可以做到很大的功率。大惯量，最高转动速度低，且随着功率增大而快速降低。因而适合做低速平稳运行的应用。 3. 永磁交流伺服电动机简介 20 世纪80 年代以来，随着集成电路、电力电子技术和交流可变速驱动技术的发展，永磁交流伺服驱动技术有了突出的发展，各国著名电气厂商相继推出各自的交流伺服电动机和伺服驱动器系列产品并不断完善和更新。交流伺服系统已成为当代高性能伺服系统的主要发展方向，使原来的直流伺服面临被淘汰的危机。90 年代以后，世界各国已经商品化了的交流伺服系统是采用全数字控制的正弦

And more importantly, if followed some of the principles of good design, it can be said of separating and content to create high-quality, reusable, easy to maintain and modify the application. For example, if the document in HTML embedded Java code too much (script), will lead the developed application is extremely complex, difficult to read, it is not easy reuse, but also for future maintenance and modification will also cause difficulties. In fact, CSDN the JSP / Servlet forum, can often see some questions, the code is very long, can logic is not very clear, a large number of HTML and Java code mixed together. This is the random development of the defects. Early dynamic pages mainly CGI (Common Gateway Interface, public Gateway Interface) technology, you can use different languages of the CGI programs, such as VB, C / C + + or Delphi, and so on. Though the technology of CGI is developed and powerful, because of difficulties in programming, and low efficiency, modify complex shortcomings, it is gradually being replaced by the trend. Of all the new technology, JSP / Servlet with more efficient and easy to program, more powerful, more secure and has a good portability, they have been many people believe that the future is the most dynamic site of the future development of technology. Similar to CGI, Servlet support request / response model. When a customer submit a request to the server, the server presented the request Servlet, Servlet responsible for handling requests and generate a response, and then gave the server, and then from the server sent to

中英文对照外文翻译文献 (文档含英文原文和中文翻译) 外文文献： DC Motor Calculations Overview Now that we have a good understanding of dc generators, we can begin our study of dc motors. Direct-current motors transform electrical energy into mechanical energy. They drive devices such as hoists, fans, pumps, calendars, punch-presses, and cars. These devices may have a definite torque-speed characteristic (such as a pump or fan) or a highly variable one (such as a hoist or automobile). The torque-speed characteristic of the motor must be adapted to the type of the load it has to drive, and this requirement has given rise to three basic types of motors: 1.
Shunt motors 2. Series motors 3. Compound motors Direct-current motors are seldom used in ordinary industrial applications because all electric utility systems furnish alternating current. However, for special applications such as in steel mills, mines, and electric trains, it is sometimes advantageous to transform the alternating current into direct current in order to use dc motors. The reason is that the torque-speed characteristics of dc motors can be varied over a wide range while retaining high efficiency. Today, this general statement can be challenged because the availability of sophisticated electronic drives has made it possible to use alternating current motors for variable speed applications. Nevertheless, there are millions of dc motors still in service and thousands more are being produced every year. Counter-electromotive force (cemf) Direct-current motors are built the same way as generators are; consequently, a dc machine can operate either as a motor or as a generator. To illustrate, consider a dc generator in which the armature, initially at rest, is connected to a dc source E s by means of a switch (Fig. 5.1). The armature has a resistance R, and the magnetic field is created by a set of permanent magnets. As soon as the switch is closed, a large current flows in the armature because its resistance is very low. The individual armature conductors are immediately subjected to a force because they are immersed in the magnetic field created by the permanent magnets. These forces add up to produce a powerful torque, causing the armature to rotate. Figure 5.1 Starting a dc motor across the line.

步进电机的知识 什么是步进电机： 步进电机是一种把电脉冲转化为角位移的执行机构。通俗的说：当驱动程序收到一个步进脉冲信号，将驱动步进电机轴旋转一个固定的角度（步进角）。您可以通过控制脉冲个数来控制角位移，从而达到准确定位的目的;同时，你可以通过控制脉冲频率来控制电机的旋转速度和加速度，实现速度控制的目的。 步进电机的种类： 步进电机分为三种：永磁式（PM），反应式（VR）和混合式（HR）永磁式步进电机一般为两相，转矩和体积较小，步进角一步7.5度或15度;反应式一般有三相可以实现大转矩输出，步进角一般是1.5度，但噪声和振动大。在欧洲和美洲80个国家已被淘汰;混合式步进是混合了永磁式和反应的优势。它由两相和五相：一般两相的步距角是1.8度，而的五相步距角为0.72度。是使用最广泛的的步进电机。 步进电机允许的最高表面温度 步进电机温度过高首先会的磁性材料退磁，导致转矩降低甚至失步，电机表面温度允许的最大值取决于的磁性材料退磁点;一般来说，磁性材料退磁点在摄氏130度以上有些材料甚至高达摄氏200度高，所以步进电机表面温度在摄氏80-90度是正常的。 步进电机精度为多少？是否累积 一般步进电机的精度为步进角的3-5%，且不累积 如何确定步进电机驱动器直流电源 A.电压确定 混合式步进电机驱动器的电源电压范围较广（比如IM483的供电电压12?48VDC），电源电压通常根据电机的转速和响应要求来选择。如果要求较快的运行速度较高的响应速度就选用较高的电压，但注意电源电压的峰值不能超过驱动器的最大输入电压，否则可能会损坏驱动器。 B.电流确定 电源电流一般根据输出相电流I来确定。如果采用线性电源，电源电流一般可取I的1.1?1.3倍;如果采用开关电源，电源电流一般可取I的1.5?2.0倍。 步进电机的主要特性 在步进电机关机时要确保没有脉冲信号，当电机运行时 如果加入适当的脉冲信号，它会转过一定的角度（称为步距角是）。转速与脉冲频率成正比。 2龙式步进电机步距角7.5度，旋转360度，需要48个脉冲来完成。 3步进电机具有快速启动和停止的优良特性。 4只要改变脉冲，可以很容易地改变电机轴旋转的方向。 因此，目前的打印机，绘图仪，机器人设备以步进电机作为动力核心。 步进电机控制的例子 我们以四相单极步进电机为例： 四个相绕组引出四个相和两个公共线（连接到正极）。一相接地。会被激发，。我们使用四相八拍控制，即第1阶段第2阶段交替反过来，会提高分辨率。步距角0.9°，可以转移到控制电机励磁是为了转移如下： 如果电机反转的要求，传输的激励信号可以逆转的。2控制方案 控制系统框图如下
