In the traditional electrical engineering industry, most of the mechanical control components are used to control the opening, running, shifting and closing of the equipment. The mechanical control components can only rely on manual manual contact control. Some of the equipments are bulky, cumbersome and dangerous. Automation is the main technical core in motor control, which directly affects the control mode of motor control. The following is a brief introduction to the common operation techniques and methods of hydraulic motor control by Da Lan Motor.
Before the computer remote control system was added, the motor control was mainly controlled by the alternating current control. With the integration of the computer remote control technology, the motor control mode has undergone new changes. The remote communication technology has become the new dominant in the hydraulic motor control mode. The remote communication technology has completely changed the control mode of the electrical equipment. Through the control of the computer, the processing is not timely due to space constraints and the safety hazards caused by the manual, and the motor control of one person to multiple devices can be realized, saving Human Resources.
Embedded technology is also an important technical tool in the modern application of motor control. Its application, on the one hand, guarantees the smooth communication of remote communication, on the other hand, because of the compact size advantage of the embedded system, it not only saves the system space of electrical equipment, but also facilitates the implementation and development of remote control operations, and can also The operation of electrical equipment provides greater security.
Automation is the core of motor control, and modern motor control systems are inseparable from the support of electrical automation systems. The electrical automation technology is integrated into the motor control. Through the electrical automation system, the issuance and reception of commands are processed by the control center to complete the operation process of the entire system. The motor control equipment should be designed with due consideration of the key elements and designed in a targeted manner so that the motor control equipment can fully meet the functional requirements of the electrical equipment.
Operation of the electrical equipment:
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 full voltage direct start mode, it can effectively adapt to 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.
Modern operating 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.
