Changsha Changli Group Co., Ltd.

Its core business is electric motor manufacturing.

Key products include standard asynchronous motors, variable-frequency speed-regulating motors, permanent magnet motors, high-efficiency energy-saving motors, wound-rotor motors, and large synchronous motors.

The products have a wide range of applications.

They are used in industries such as metallurgy, papermaking, chemicals, cement machinery, electric power, and water conservancy, and are exported to regions including Europe, Southeast Asia, the United States, and Russia.

TL and TLKS Series Vertical Synchronous Motors

These motors serve as core drive equipment for the water conservancy industry. Characterized by high efficiency, strong interference resistance, and excellent stability, the TL and TLKS series vertical synchronous motors are primarily used to drive equipment such as axial-flow pumps, centrifugal pumps, mixed-flow pumps, and submersible pumps in water conservancy projects.

This series features enhanced operational reliability, a compact structure, reduced vibration and noise, suitability for a wider range of outdoor applications, lighter weight, and higher efficiency. It is a mature product offering the advantages of reliable performance, compact design, low vibration and noise, broad outdoor applicability, reduced weight, and superior efficiency.

TL series synchronous motors comply with the standard JB/T 8667.2, "Technical Specifications for Large Three-Phase Synchronous Motors – Part 2: TL Series." Their power ratings and mounting dimensions meet the company's internal standards as well as IEC (International Electrotechnical Commission) and German standards; they serve as matching components for related equipment and can also act as replacements for certain well-known products.
