Low-voltage inverter automation level should be improved

The "Twelfth Five-Year Plan" proposes to "renovate and upgrade the manufacturing industry," including "developing advanced equipment manufacturing industry," and raising the level of automation will become the focus.

Under the influence of downstream use conditions, low-voltage frequency conversion technology emphasizes the adjustment of precision and scope. In the field of industrial automation, it is closely related to front-end PLC control and back-end servo motors, and together constitute an industrial automation control system.

Similar to high-voltage frequency conversion, low-voltage frequency conversion is also divided into high-end market, mid-end market and low-end market. Listed companies such as Zhonghuichuan Technology and Inventronics mainly participate in high-end market competition, and automation level upgrade emphasizes frequency technology in the fine field from the technical level. Applications will therefore mainly discuss high-end markets. Manufacturing equipment upgrade is a gradual and long-term process

Low-voltage inverters and PLCs, servo motors, and other components form an industrial automation control system. Downstream involves multiple sub-sectors in the manufacturing industry. Unlike high-voltage inverters, which are mainly affected by national policies, the demand for low-voltage inverters is related to the overall level of industrial development. Future equipment upgrades will be implemented. It is a gradual and long-term process, and it is expected that the industry can maintain a stable growth of about 15% over a period of time.

From the perspective of subdivided industries, the growth rate of low-voltage inverter equipment used in elevators, injection molding machines, and rail transit is expected to exceed the industry average and become the focus of development.

The high-end market of low-voltage frequency conversion industry is still dominated by foreign-funded products, accounting for more than 80% of the total share. The number of domestic-funded enterprises currently participating in competition is small, the share is low, and the frequency converters are centralized in production, and the core products of the control layer and the executive layer are lacking. The future development trend It will shift towards a high-profit model that provides comprehensive solutions. Import substitution will be the main reason for the industry leader to maintain a high growth rate for some time.

China's low-voltage frequency conversion market has a low degree of concentration, and the dominant areas of major manufacturers are relatively dispersed. For example, Inventronics is mainly concentrated in the lifting, drawing, and coal industries, while Incotech's technology relies on the elevator and injection molding machine market. Because of obvious product price advantages, it will continue to seize the share of foreign capital in the future. There is no fierce competition among domestic-funded enterprises in the short term, so it is expected to continue the trend of high gross profit and high growth. The main low-voltage inverter manufacturers advantage areas.

Domestic inverter production companies represented by Inventronics and Huichuan began to get involved in products such as PLCs and servos. The future development will aim at providing customized solutions. At present, the development models of the two companies are different, and they will face the challenges of integrating sales channels and implementing technology in the control layer.
