Common operating skills and methods of motor control
2.1 Operation of the electrical equipment.
The motor equipment is a very important part of the whole motor control system, but it is only a small part of the whole system. Therefore, the operation skill of the motor equipment alone is not equivalent to the motor control technology itself, one of the knowledge points and control techniques. composition. Compared with the traditional method, the basic principle of motor control is the same. The main principle of motor control is the control of current. By changing the motor current, the control of the motor's switching and shifting is realized. Since the current of the motor equipment varies depending on the field of application and the manner in which it is required, alternating current or direct current is generally used.
In addition, since the three-phase electric mode is generally adopted, for the motor control, in the control of the operation of the motor and the control of the speed regulation, corresponding control analysis is required. The control from the motor start is different depending on the different working environment of the motor. With the full voltage direct start mode, the motor can be efficiently started, and the output power is also the largest, which can effectively adapt to the high power working environment. However, this kind of startup method also has certain drawbacks. Because the power demand in the startup process is extremely large, the energy consumption is also extremely high. It should be selected for the necessary engineering operations, otherwise it will lead to waste of energy. Buck start is also a common starting method in motor control, but buck start is not suitable for high-power output environment, because the voltage reduction will affect the efficiency of work to a certain extent. In the engineering phase where the output environment is relatively stable, take The step of step-down startup is conducive to energy saving in operation and operation. In addition to the above two motor start control modes, there is also a start mode that neutralizes the characteristics of direct start and buck start. It is also the most commonly used start mode, which is to increase the start of the electronic rotary resistance. That is to say, the energy-saving of the project can ensure the stable output of the power, and the starting mode is relatively safer and more stable.
2.2 Modern operation technology.
The operation of the motor equipment is only a small part of the motor control system. In addition to the motor equipment, the computer remote control system, embedded system and electrical automation system are also an important part of the modern motor control system. The application of modern technology is the intelligent feature of the motor control system. Therefore, the deep understanding of the remote control system and the continuous improvement of the knowledge level of the remote automation control technology are also an essential part of the motor operation technology. Based on the understanding of the motor control system and modern control technology, it will also continue to improve with the continuous improvement of the motor control system and the continuous increase in technology content.
In addition, industrial production will have a certain impact on people's living environment, especially in terms of energy consumption. Therefore, in the design of motor control system, more and more ideas of energy saving and environmental protection are integrated into the design. Therefore, in the motor control operation skills, we should also fully consider the requirements of energy conservation, and carry out scientific technical improvement to save energy as much as possible while meeting the needs of production energy.
In summary, electrical engineering of electrical engineering is not a simple matter of learning. From the design of the operating system to the choice of methods in operation, the efficiency of the motor may be affected. Therefore, only sufficient research is carried out on the motor. Sufficient analysis of the working environment and work requirements is the design of the motor control system to meet the needs of electrical engineering and energy-saving operations, and the appropriate use of appropriate skills and methods to ensure the efficiency and safety of motor control. At the same time, we must use new scientific and technological strength, constantly improve the operation skills of the motor control system, and let science and technology provide assistance for the development of modern industry.
