China’s Ministry of Agriculture continues to expand the construction of national smart aquaculture demonstration parks. A key system being promoted combines real‑time dissolved oxygen (DO) monitoring with variable frequency drives (VFD) and permanent magnet synchronous motors (PMSM). Sensors placed in the pond continuously measure oxygen levels, and the controller automatically adjusts the aerator’s speed and running duration accordingly. This means aerators operate only when needed, without requiring manual on‑site supervision.
In pilot intelligent breeding parks in Hubei and Jiangsu, adoption of this integrated PMSM aeration solution has led to reduced overall power consumption compared to traditional timer‑based or always‑on systems. At the same time, more stable dissolved oxygen levels contribute to better feed conversion. Domestic component suppliers are receiving growing orders for customized permanent magnet rotors, frequency control panels, and structural accessories. Industry experts view intelligent and energy‑saving transformation as a long‑term direction for China’s aquaculture sector, creating sustained demand for high‑efficiency permanent magnet motor parts.
