Low-Speed Permanent Magnet Motor System for Air-Cooled Islands

The next-generation air-cooling island utilizes a low-speed permanent‑magnet drive system, in which a low-speed permanent‑magnet motor directly drives the fan blades, resulting in a short transmission chain and high transmission efficiency. The permanent‑magnet motor boasts a wide high-efficiency operating range, enabling low-speed, light‑load operation to achieve derating, thereby reducing motor downtime and minimizing risks to service life. An intelligent control system provides smart tracking and rapid response, optimizing system operating parameters to enhance cooling capacity while improving overall system efficiency.

Low-Profile Permanent Magnet System for Vertical Mills

The next-generation vertical coal mill features a permanent‑magnet drive system with an integrated design that combines thrust bearings, a thrust disc, and a low‑speed, high‑torque permanent‑magnet motor, enabling direct drive of the mill. A unique, specialized design further compactes the motor's structure; compared with conventional low‑speed permanent‑magnet motors, it boasts a smaller footprint and lighter weight, allowing it to replace existing drive systems within the limited installation space of a vertical coal mill while saving space. Its simple architecture ensures easy installation. The intelligent control system delivers smart tracking and rapid response, reducing specific power consumption for pulverization, increasing mill output, and enhancing overall mill performance.
