2) Reluctance machines (Step machines). Reluctance machines (Reluctance motor) has no windings in rotor, only a ferromagnetic material shaped so that "electromagnets" in stator can "grab" the teeth in rotor and move it a little. The electromagnets are then turned off, while another set of electromagnets is turned on to move stator further. Another name is step motor, and it is suited for low speed and accurate position control. Reluctance machines can be supplied with PMs in stator to improve performance.

With that in mind, it is correct to classify common electric machines as: 1) Electromagnetic-rotor machines Electromagnetic-rotor machines are machines having some kind of electric current in rotor which creates a magnetic field which interacts with the stator windings. The rotor current can be the internal current in a permanent magnet (PM machine), a current supplied to rotor through brushes (Brushed machine) or a current set up in closed rotor windings by a varying magnetic field (Induction machine).

一、History about electronics(电子技术,电子学,电子设备)1、The English names for the department and the majors电气工程系Department of Electrical Engineering电气化铁道工程Electrified railway engineering电气自动化技术Electrical automation technology电子信息工程技术Technology of electrical and Information Engineering 应用电子技术The application of electronic technology电子工艺与管理Electronic technology and management供用电技术Technology power电机与电器Motor and electric appliances铁道通信信号Railway communication signal2、History about electronicsThere can be no doubt that the 1900s is remembered as the electronic century. Of course there have been other great advances, in medicine(医学领域), in transport, in science, in commerce(商业领域), and many other fields but where would they have been without the instruments and devices that electronics has provided?How would you see a 3D virtual reality image(3D虚拟现实影像) of your beating heart with no electronics? Would you go to a pop concert(流行音乐会)that had no amplifiers(【电子】放大器,扩音器), large screens or lighting effects? Don’t say you would rather watch TV-there would not be any.Electronics in the early 20th century started thriving at a greater speed unlike the pre-20th century developments. The radio(无线电) invented by the Italian genius Marconi and the work of Henry Hertz opened the road to further discoveries and inventions.In the first decade the new thing that was welcome to the technical world was the vacuum tube(真空管,电子管). The vacuum tubes at that time worked as a miraculous component for the radio devices.The invention of the television was a miraculous thing for the mankind. It was revolution in both communication technology(通信技术) and also for the world media. The distances between the continents did not seem to be far enough.The credit goes to the British engineer John Logic Baird who followed the footprints of Marconi and tried to send the images in the same way as the speech. After a long experiment he found that a series of static pictures, if sent within a small interval of time in between them, seem to be moving.The real electronics what it is called today was actually started after the discovery of the transistor(晶体管) effect. Transistor opened the road for the computing world. Computers of various types started hitting the market and the research works got a boost.Some other problems were also there like the assembling(装配,聚集) of the electronic components(电子元器件) on a single mother board(母板,主插件板). Jack Kilby in Texas Instruments found a very nice solution.He suggested to throw away all the wires(wire:电线,电报) and tried to connect the resistors(电阻器), capacitors(电容器) and transistors on the samepiece of wafer(圆片,晶片) internally. Surprisingly his ideas worked and gave birth to the integrated circuit(集成电路) industries.二、Introduction to some courses1、Direct current circuits & Alternating current circuits(直流电路与交流电路)This course covers the fundamental theory of passive devices (无源器件)(resistor, capacitor, and inductor(电感器)) and electrical networks(电子、电路网络) supplied by a DC source(直流电源), then an introduction to the effects of alternating voltage and current in passive electrical circuits(electrical circuit:电路)is given. This module also covers DC machines, three phase circuits(三相电路)and transformers(变压器).这门课程包括了无源器件(电阻,电容和电感)的基本理论和用直流电源供电的电路网络,接着介绍无源电路中的交流电流和交流电压的作用,这个课程模块还包括了直流电机,三相电路和变压器。

Back in 1968, a computer scientist named Alan Kay proposed that with advances in flat-panel display technology, user interfaces, miniaturization of computer components and some experimental work in WiFi technology, you could develop an all-in-one computing device. He developed the idea further, suggesting that such a device would be perfect as an educational tool for schoolchildren. In 1972, he published a paper about the device and called it the Dynabook.The sketches of the Dynabook show a device very similar to the tablet computers we have today, with a couple of exceptions. The Dynabook had both a screen and a keyboard all on the same plane. But Key's vision went even further. He predicted that with the right touch-screen technology, you could do away with the physical keyboard and display a virtual keyboard in any configuration on the screen itself.Key was ahead of his time. It would take nearly four decades before a tablet similar to the one he imagined took the public by storm. But that doesn't mean there were no tablet computers on the market between the Dynabook concept and Apple's famed iPad.One early tablet was the GRiDPad. First produced in 1989, the GRiDPad included a monochromatic capacitance touch screen and a wired stylus. It weighed just under 5 pounds (2.26 kilograms). Compared to today's tablets, the GRiDPad was bulky and heavy, with a short battery life of only three hours. The man behind the GRiDPad was Jeff Hawkins, who later founded Palm.Other pen-based tablet computers followed but none received much support from the public. Apple first entered the tablet battlefield with the Newton, a device that's received equal amounts of love and ridicule over the years. Much of the criticism for the Newton focuses on its handwriting-recognition software.It really wasn't until Steve Jobs revealed the first iPad to an eager crowd that tablet computers became a viable consumer product. Today, companies like Apple, Google, Microsoft and HP are trying to predict consumer needs while designing the next generation of tablet devices.C.2 A Brief History of satellite communicationIn an article in Wireless World in 1945, Arthur C. Clarke proposed the idea of placing satellites in geostationary orbit around Earth such that three equally spaced satellites could provide worldwide coverage. However, it was not until 1957 that the Soviet Union launched the first satellite Sputnik 1, which was followed in early 1958 by the U.S. Army’s Explorer 1. Both Sputnik and Explorer transmitted telemetry information.The first communications satellite, the Signal Communicating Orbit Repeater Experiment (SCORE), was launched in 1958 by the U.S. Air Force. SCORE was a delayed-repeater satellite, which received signals from Earth at 150 MHz and stored them on tape for later retransmission. A further experimental communication satellite, Echo 1, was launched on August 12, 1960 and placed into inclined orbit at about 1500 km above Earth. Echo 1 was an aluminized plastic balloon with a diameter of 30 m and a weight of 75.3 kg. Echo 1 successfully demonstrated the first two-way voice communications by satellite.On October 4, 1960, the U.S. Department of Defense launched Courier into an elliptical orbit between 956 and 1240 km, with a period of 107 min. Although Courier lasted only 17 days, it was used for real-time voice, data, and facsimile transmission. The satellite also had five tape recorders onboard; four were used for delayed repetition of digital information, and the other for delayed repetition of analog messages.Direct-repeated satellite transmission began with the launch of Telstar I on July 10, 1962. Telstar I was an 87-cm, 80-kg sphere placed in low-Earth orbit between 960 and 6140 km, with an orbital period of 158 min. Telstar I was the first satellite to be able to transmit and receive simultaneously and was used for experimental telephone, image, and television transmission. However, on February 21, 1963, Telstar I suffered damage caused by the newly discovered Van Allen belts.Telstar II was made more radiation resistant and was launched on May 7, 1963. Telstar II was a straight repeater with a 6.5-GHz uplink and a 4.1-GHz downlink. The satellite power amplifier used a specially developed 2-W traveling wave tube. Along with its other capabilities, the broadband amplifier was able to relay color TV transmissions. The first successful trans-Atlantic transmission of video was accomplished with Telstar II , which also incorporated radiation measurements and experiments that exposed semiconductor components to space radiation.The first satellites placed in geostationary orbit were the synchronous communication (SYNCOM ) satellites launched by NASA in 1963. SYNCOM I failed on injection into orbit. However, SYNCOM II was successfully launched on July 26, 1964 and provided telephone, teletype, and facsimile transmission. SYNCOM III was launched on August 19, 1964 and transmitted TV pictures from the Tokyo Olympics. The International Telecommunications by Satellite (INTELSAT) consortium was founded in July 1964 with the charter to design, construct, establish, and maintain the operation of a global commercial communications system on a nondiscriminatory basis. The INTELSAT network started with the launch on April 6, 1965, of INTELSAT I, also called Early Bird. On June 28, 1965, INTELSAT I began providing 240 commercial international telephone channels as well as TV transmission between the United States and Europe.In 1979, INMARSAT established a third global system. In 1995, the INMARSAT name was changed to the International Mobile Satellite Organization to reflect the fact that the organization had evolved to become the only provider of global mobile satellite communications at sea, in the air, and on the land.Early telecommunication satellites were mainly used for long-distance continental and intercontinental broadband, narrowband, and TV transmission. With the advent of broadband optical fiber transmission, satellite services shifted focus to TV distribution, and to point-to-multipoint and very small aperture terminal (VSAT) applications. Satellite transmission is currently undergoing further significant growth with the introduction of mobile satellite systems for personal communications and fixed satellite systems for broadband data transmission.C.3 SmartphonesThink of a daily task, any daily task, and it's likely there's a specialized, pocket-sized device designed to help you accomplish it. You can get a separate, tiny and powerful machine to make phone calls, keep your calendar and address book, entertain you, play your music, give directions, take pictures, check your e-mail, and do countless other things. But how many pockets do you have? Handheld devices become as clunky as a room-sized supercomputer when you have to carry four of them around with you every day.A smartphone is one device that can take care of all of your handheld computing and communication needs in a single, small package. It's not so much a distinct class of products as it is a different set of standards for cell phones to live up to.Unlike many traditional cell phones, smartphones allow individual users to install, configure and run applications of their choosing. A smartphone offers the ability to conform the device to your particular way of doing things. Most standard cell-phone software offers only limited choices for re-configuration, forcing you to adapt to the way it's set up. On a standard phone, whether or not you like the built-in calendar application, you are stuck with it except for a few minor tweaks. If that phone were a smartphone, you could install any compatible calendar application you like.Here's a list of some of the things smartphones can do:•Send and receive mobile phone calls•Personal Information Management (PIM) including notes, calendar and to-do list•Communication with laptop or desktop computers•Data synchronization with applications like Microsoft Outlook•E-mail•Instant messaging•Applications such as word processing programs or video games•Play audio and video files in some standard formatsC.4 Analog, Digital and HDTVFor years, watching TV has involved analog signals and cathode ray tube (CRT) sets. The signal is made of continually varying radio waves that the TV translates into a picture and sound. An analog signal can reach a person's TV over the air, through a cable or via satellite. Digital signals, like the ones from DVD players, are converted to analog when played on traditional TVs.This system has worked pretty well for a long time, but it has some limitations:•Conventional CRT sets display around 480 visible lines of pixels. Broadcasters have been sending signals that work well with this resolution for years, and they can't fit enough resolution to fill a huge television into the analog signal.•Analog pictures are interlaced - a CRT's electron gun paints only half the lines for each pass down the screen. On some TVs, interlacing makes the picture flicker.•Converting video to analog format lowers its quality.United States broadcasting is currently changing to digital television (DTV). A digital signal transmits the information for video and sound as ones and zeros instead of as a wave. For over-the-air broadcasting, DTV will generally use the UHF portion of the radio spectrum with a 6 MHz bandwidth, just like analog TV signals do.DTV has several advantages:•The picture, even when displayed on a small TV, is better quality.• A digital signal can support a higher resolution, so the picture will still look good when shown on a larger TV screen.•The video can be progressive rather than interlaced - the screen shows the entire picture for every frame instead of every other line of pixels.•TV stations can broadcast several signals using the same bandwidth. This is called multicasting.•If broadcasters choose to, they can include interactive content or additional information with the DTV signal.•It can support high-definition (HDTV) broadcasts.DTV also has one really big disadvantage: Analog TVs can't decode and display digital signals. When analog broadcasting ends, you'll only be able to watch TV on your trusty old set if you have cable or satellite service transmitting analog signals or if you have a set-top digital converter.C.5 SoCThe semiconductor industry has continued to make impressive improvements in the achievable density of very large-scale integrated (VLSI) circuits. In order to keep pace with the levels of integration available, design engineers have developed new methodologies and techniques to manage the increased complexity inherent in these large chips. One such emerging methodology is system-on-chip (SoC) design, wherein predesigned and pre-verified blocks often called intellectual property (IP) blocks, IP cores, or virtual components are obtained from internal sources, or third parties, and combined on a single chip.These reusable IP cores may include embedded processors, memory blocks, interface blocks, analog blocks, and components that handle application specific processing functions. Corresponding software components are also provided in a reusable form and may include real-time operating systems and kernels, library functions, and device drivers.Large productivity gains can be achieved using this SoC/IP approach. In fact, rather than implementing each of these components separately, the role of the SoC designer is to integrate them onto a chip to implement complex functions in a relatively short amount of time.The integration process involves connecting the IP blocks to the communication network, implementing design-for-test (DFT) techniques and using methodologies to verify and validate the overall system-level design. Even larger productivity gains are possible if the system is architected as a platform in such as way that derivative designs can be generated quickly.In the past, the concept of SoC simply implied higher and higher levels of integration. That is, it was viewed as migrating a multichip system-on-board (SoB) to a single chip containing digital logic, memory, analog/mixed signal, and RF blocks. The primary drivers for this direction were the reduction of power, smaller form factor, and lower overall cost. It is important to recognize that integrating more and more functionality on a chip has always existed as a trend by virtue of Moore’s Law, which predicts that the number of transistors on a chip will double every 18-24 months. The challenge is to increase designer productivity to keep pace with Moore’s Law. Therefore, today’s notion of SoC is defined in terms of overall productivity gains through reusable design and integration of components.。
