For a specific single application of the customer, due to its special technology and cost indicators, general servo products (including imported products) are difficult to meet the requirements, which requires tailoring, embedding user-specific motion control functions in the original servo motor driver. Significantly reduce product costs
In recent years, China has been developing from a manufacturing powerhouse to a manufacturing powerhouse. Due to the state's emphasis on manufacturing equipment and its technological transformation work, as the performance-price ratio of the all-digital AC permanent magnet servo system is gradually improved, AC servo motors are used as controls. The market demand for high-end precision components of motors will grow steadily, and its application prospects will be very promising in the past five years.
AC permanent magnet servo motor gradually becomes the protagonist
Before 1990, due to technical costs and other reasons, domestic servo motors were mainly DC permanent magnet brush motors and stepper motors, and they were mainly concentrated in the machine tool and defense industry. After 1990, the imported permanent magnet AC servo motor system gradually entered China. During this period, thanks to the development of rare earth permanent magnet materials, the rapid development of power electronics and microelectronics technology, the drive technology of AC servo motor also quickly transitioned from analog. To all digital. Since the drive device of the AC servo motor adopts advanced all-digital drive control technology, the hardware structure is simple, the parameter adjustment is convenient, the consistency of product production is increased, and complex motor control algorithms and intelligent control functions such as gain can be integrated. Automatic adjustment, network communication functions, etc., greatly expand the applicable field of AC servo motor; in addition, with various industries, such as machine tools, printing equipment, packaging equipment, textile equipment, laser processing equipment, robots, automated production lines, etc. The requirements for processing efficiency and work reliability are constantly increasing. The demand for AC servo motors will increase rapidly in these fields. The AC servo will gradually replace the original DC brush servo motor and stepper motor. In 2002, customers from Beijing and Lishi Motor Technology Co., Ltd. found that nearly 51% of the original DC servo and stepper motor customers are ready to replace the permanent magnet AC servo system, the power is less than 3kW, of which 85% is 1000W. The following servo motor.
The market demand for dedicated servo motors cannot be ignored
For a specific single application of the customer, due to its special technology and cost indicators, general servo products (including imported products) are difficult to meet the requirements, which requires tailoring, embedding user-specific motion control functions in the original servo motor driver. Significantly reduce product costs. These typical industry customer needs have a certain volume and require high reliability. The digital servo products of Beijing Heli Motor Technology Co., Ltd. have mature applications in textile equipment, printing equipment, elevator equipment, robots and other industries.
Intelligent servo motors will be widely used
On the basis of the universal servo drive, additional PL C and motion control functions, plus its own network communication function, form an independent single-axis motion controller, which independently performs certain motion control functions, such as point-to-point positioning. Etc., can be widely used in applications such as automated production lines.
