In recent years, China has basically kept pace with the international level in the research and development of high-efficiency motors, and the technological progress is very optimistic. According to the motor industry market survey and analysis report, China's annual electricity consumption of electric motors has exceeded 2 trillion kWh, accounting for 60% of the national electricity consumption. It is not difficult to see that the promotion of high-efficiency motors in the domestic market is particularly important. In the industrial field, the electricity consumption of electric motors accounts for about 75% of the total amount of industrial electricity. Motor energy conservation has become the key to industrial energy conservation.
In the industrial field, the electricity consumption of electric motors accounts for about 75% of the total amount of industrial electricity. Motor energy conservation has become the key to industrial energy conservation. With the dual pressures of energy saving, emission reduction and environmental protection, energy-saving equipment represented by high-efficiency motors has attracted much attention in the market. At the same time, the development of electronic components based on high-efficiency motors has become a topic of interest to many well-known semiconductor companies.
In the field of modern motor applications, industrial servos will play an increasingly important role. The requirements for motor control have not only stayed in general-purpose inverters and speed control that meet energy-saving requirements, but more and more applications and fields need to be precise. Position control and current control; servo control is an important actuator for industrial production lines, industrial automation equipment and machinery, as well as intelligent logistics and robotics. Cost and sensorless control are more considered than in the home sector. In the automotive and transportation sectors, reliability will be the most important factor.
In terms of energy consumption, the proportion of industrial consumption is very high, and in terms of industrial energy consumption, motor consumption also accounts for a large proportion. Relevant statistics show that about 40% of energy consumption is generated by motors, so how to improve motor efficiency, how to reduce motor energy consumption has become a concern in the entire industrial automation field. In order to solve this problem, the efficiency and intelligence of industrial motors (also called servoization) has become the focus of technology development of ADI. In short, reducing energy consumption can be achieved by directly controlling the speed of the motor. For example, the frequency converter can achieve speed control through speed control. On the other hand, we will set up a control called torque, plus servo and high-end overall servo, based on the simplest motor speed control, by increasing the current and position sampling, the overall motor control efficiency and accuracy will There is a significant increase, which will increase the requirements for the sensing technology used.
In the field of motor control for green energy saving requirements, ADI can provide a variety of products and technical solutions. We can take a servo control solution as an example. ADI offers a complete product portfolio that includes analog-to-digital/digital-to-analog converters, amplifiers, embedded processors, iCoupler digital isolators, and power management devices; The device and increased system integration help to achieve an updated topology design that provides higher added value than the average customer. The performance of the servo drive system is closely related to the performance and accuracy of the motion control system that the user ultimately constructs. In most cases, the final use can be a high-precision CNC machine system, motion control system or robot system. It is required to accurately control the position and torque of the motor. Analog Devices is able to offer a complete solution covering all critical devices in the signal chain.
For motor control systems, industrial system design requirements are low power consumption and high efficiency. ADI offers a single device and a complete product signal chain to speed up system design; in the signal chain, ADI provides feedback and detection, Products such as isolation, power management, interfaces, embedded processing and communications are second to none in terms of performance and quality, and can also reduce costs from the system level. ADI's broad portfolio of technologies, including world-class isolators, processors, converters, and mixed-signal front ends, meets engineers' needs for any motor control solution, now and in the future.
