The development trend of servo motors
As China's transition from a manufacturing power to a manufacturing powerhouse and the performance and price ratio of a digital AC servo system are gradually improved, the AC servo system is a high-end precision component for controlling motors, and its market in the industry is also steadily rising. . As the most important part of CNC machine tools, the servo system has always been one of the important indicators that affect the processing performance of the system.
In recent years, around the improvement of the dynamic and static characteristics of the servo system, various servo drive technologies have also been developed. The key factor determining the performance of the AC servo system is still the servo control technology, but because the AC servo system itself has extremely advanced control principles and low-cost, maintenance-free features, not to mention its control characteristics are also comprehensively beyond DC. In the future, the servo system will replace most of the DC servo system in the future development process, and will analyze it according to the current operation mode. In the future, it will be more efficient, telling, high precision and high performance.
Not only that, with the current large-scale promotion of intelligence and the prevalence of networked modularization, modern AC servo drive devices also have the function of parameter memory, as well as the function of diagnosis and analysis of their own faults, and some servo motors even It also has the performance of identifying parameters, and it can automatically suppress the vibration when it is found, and automatically measure and zero the encoder. These are the development trend of the servo motor in the intelligent method. The key development direction of network is how to adapt to the requirements of high-performance motion control for real-time, synchronization and reliability of data transmission. The successful development of high-end CNC systems also indicates that networked digital servo development has become a top priority now, as well as servo motor drives, power supplies, regenerative braking, and communication between motors and motors are constantly moving toward modularity.
