"Electromechanical Drive Control" study notes

from the textbook of electromechanical drive control, it is easy to find the definition of the concept of electromechanical drive control, which represents a complete set of electrical systems that represent the motors that drive production machinery and control motors. The purpose of this technology is to convert electrical energy into mechanical energy, to achieve the start, stop and speed regulation of production machinery, to meet the requirements of various production processes and to ensure the normal production process. But there are many ways to achieve this goal, with the rapid development of information technology, more and more processes in the production process can be programmed through the computer processing, to achieve the production of machinery and equipment, production lines, workshops and even the entire factory automation is already within reach. The faster the technology develops, the more disciplines are blended together, which requires modern engineers to achieve a certain level of discipline at the same time, but also to other disciplines have a certain grasp and understanding. For example, in our machinery, design a production line, not only to consider the motor drive, machining and other aspects of the problem, but also to consider the material wear resistance, heat dissipation, as well as the product transmission line in the geometry of the scientific, and then consider the operation of the processing program. Of course, mastering these technologies and science is not a one-day work, the need for engineers to accumulate and exercise long-term, which requires engineers have a certain degree of learning ability, see new things can be humbly consulted and learn. If the engineer wants to reach a higher level of the realm, it must be able to digest, extrapolate, after learning the advanced technology of others can be applied, on the other side to do innovation, can surpass others, have achievements.

as an undergraduate student, I may not be able to achieve a certain degree in my own field of study, not to mention in other disciplines, to achieve the level of innovative engineers continue to learn. But now the technology is growing faster, many of the technology is beyond the scope of our disciplines, so we have to work with other fields of engineers to supplement their shortcomings in these areas, while learning more advanced cases, the current trend of technological development to understand the direction of our own development, and finally more practice, In the classroom to learn a lot of theory and not to the factory field visit study is just paper, many process steps on the textbook looks very easy, in fact, processing up or not, need to have a certain experience. Now many of the challenges of process automation lies here, some process operation there is "experience" problem, inexperienced novice is difficult to do, and computer program how to be called an old hand? This requires that it has a certain "eyesight", which is a variety of sensors to detect various aspects of the workpiece parameters, and the side of the processing side feedback to the host, while the processing operation of a certain correction, the acquisition and integration of parameters related to statistics and computer science and other aspects of knowledge, The sensor design also involves the knowledge of electronic semiconductors and other devices, and how to make the sensor obtain accurate parameters is a difficult problem.

Back to the electromechanical transmission control textbooks, textbooks on the class capacity is mainly related to electrical circuit knowledge, but also involves a certain knowledge of mechanics and engineering control, learning this course, we need to review and use the knowledge learned before, but also hope that the teacher can step in the lectures, Let us understand the whole structure and system of this subject. In the first three chapters of the textbook, I am more interested in the work of DC motor and mechanical characteristics, because these directly affect the characteristics of electromechanical transmission, the motor is the driving force of electromechanical transmission, through the computer program control of the motor rotation can be effectively controlled the entire transmission process, so I am more concerned about the knowledge of the motor learning.
