Competition pattern: The market share of domestic manufacturers of general servo system continues to increase, and new servo manufacturers continue to emerge. According to the latest annual report of Huichuan Technology in 2023, according to the statistics of Rui Industry, the market share of Huichuan technical servo system in 2023 has reached 28.2%, far more than Siemens, 07KT98-GJR5253100R3160 Panasonic, Yaskawa and other old foreign leaders. At the same time, a number of emerging domestic servo brands have emerged in China, such as Hexuan Technology, Wuxi Xinjie, Leisai Intelligence, etc., according to Rui industrial statistics in 2022, the market share has reached 3.4%, 2.4%, 1.3%. However, at present, in addition to Huichuan technology, other domestic brands still have a large gap in market share with foreign leading enterprises, and have a wide range of alternative space.
Comparison of servo system and inverter:
Servo system and inverter technology homology, similar function, mainly due to different application scenarios, the two can not completely replace each other.
Similarities: the servo driver and inverter in the servo system should realize the frequency conversion function, that is, the power frequency power supply is rectified into the frequency adjustable alternating current to control the motor rotation;
07KT98-GJR5253100R3160 Differences: (1) the servo drive has more accurate control technology and algorithm calculation than the general frequency converter, which can carry out accurate position control, while the frequency converter has no position loop; (2) The servo system mostly uses permanent magnet synchronous AC motor, and the inverter mainly controls the AC asynchronous motor, and the permanent magnet synchronous AC motor above 10KW is expensive due to the process limitation, so the frequency converter with higher cost performance is used in the high-power scenario, and the servo system is generally used in the low-power scenario.
In summary, the occasions that can be controlled by frequency converter can almost be replaced by servo, the key is the price (servo system is much higher than the frequency converter) and power.
