• Design of DC motor control function module based on VHDL

  2021 / 06 / 25

  With the development of society, the application of DC motor is more and more common, and the requirement of DC motor control mode is also increasing. In this paper, the design of DC motor function module based on NiosII soft core processor is proposed by using SOPC solution newly developed by Altera company, and the IP core of VHDL code generation function module is given. The generation of IP core is not only convenient for designers to use flexibly, save resources, but also greatly shorten the design cycle. Designers can call IP core directly to form NiosII system, and then download the system to FPGA. IP core not only can be used in motor control, but also can be used to control some other small appliances, full-color LED, etc. Overall hardware design of DC motor As shown in Figure 1, the whole system is controlled by FPGA chip, and its control core is NiosII soft core CPU of Altera company. This paper focuses on the design and generation of two control function modules, PWM module and speed measurement module. The two control function modules are designed and generated by VHDL hardware description language, which can be called IP core. They are compiled and simulated by QuartusII to verify their correctness. Finally, the generated user-defined interface function module is added to the top-level schematic diagram to complete the design of the whole speed regulation system.

• How effective can the hardware and electrical industry (micro motor) take advantage of the Olympic marketing

  2021 / 06 / 20

  Since the opening of the Olympic Games in London, the hearts of hundreds of millions of Chinese people have been concerned. With the news of success on the field, the mood of the audience is getting higher and higher. The sponsors of the London Olympic Games have spent a lot of money on publicity and marketing, and many other enterprises are not willing to let go of this rare marketing opportunity. Although they do not have the publicity strength of the sponsors, they also try their best to attract attention through various channels and taking advantage of the east wind of the Olympic Games www.sc-motor.cn/ . (micromotor) Xiaobian observed that before and after the Olympic Games, many domestic enterprises and manufacturers planned various promotional and promotional activities in the name of the Olympic Games. This includes a large number of furniture hardware, ceramic bathroom, electronics and electrical hardware and electrical (micro motor) related industries. These enterprises either reduce prices and promote sales through physical stores and online shopping malls, or launch award-winning activities related to the Olympic Games through microblogs, forums and other network information exchange platforms, so as to strengthen interaction with consumers and expand brand awareness and influence. In the highly competitive market environment, it's not unreasonable to carry out marketing with the help of social hot spots combined with their own, but too many enterprises carry out similar marketing activities at the same time, which is lack of innovation, not only makes consumers feel numb, but also makes enterprise marketing encounter a bottleneck. In addition, the marketing activities carried out by some enterprises in order to attract attention can cause a lot of attention in a short period of time, but because they cheat consumers and violate public values, they do great harm to the brand image of enterprises. www.sc-motor.cn/

  2021 / 06 / 15

  The electromechanical (micro motor) products mentioned in this paper include mechanical and electronic products. Among them, machinery includes construction machinery, machine tools, automobiles, internal combustion engines, mechanical basic parts, agricultural machinery, instrumentation, cultural office equipment, petrochemical general, heavy mining, electrical appliances and food packaging industries; Electronics include communication equipment, radio and television equipment, computers, home appliances and other consumer electronics, electronic measuring instruments, electronic industrial equipment, electronic components, electronic devices, medical electronics and other electronic application products, as well as electronic special materials. 1. Antidumping is the main means of Global trade remedy to China's mechanical and electronic products According to the statistics of China trade remedy information network, by the end of 2010, there were 1418 trade remedy investigations launched against China, involving 165 electromechanical (micro motor) products, accounting for 11.6% of the total number of trade remedy cases against China, ranking fifth in all industries involved. Of the 165 trade remedy investigations launched against China's machinery and electronic products, 143 were anti-dumping, accounting for 86.7% of the total number of trade remedy cases against China's machinery and electronic products; There were 6 countervailing cases, accounting for 3.6%; There were 13 safeguard measures, accounting for 7.9%; There were 3 special safeguard measures, accounting for 1.8%. Antidumping is the main means of Global trade remedy to China's mechanical and electronic products. 1. The number of global anti-dumping cases against China's machinery and electronic products is on the rise Among the 143 anti-dumping investigations against China's machinery and electronic products launched by the world, there are great changes in each period.
