High-Voltage Asynchronous Motor for Steel Industry

Product Overview

This series of motors is a high-voltage asynchronous motor independently developed by our company for the steel industry, featuring a modular design concept with compact structure, high power density, and reliable operation. The motors are widely used in power, metallurgy, mining, petrochemical, and nuclear power industries, driving various general-purpose machinery such as blowers, compressors, pumps, and crushers.

The motor adopts a box-type steel plate welded structure with excellent rigidity and strength. The advanced design and precision manufacturing processes ensure reliable performance under the demanding conditions of the steel industry — high temperature, heavy dust, and continuous operation.

Key Features

• High Efficiency & Energy Saving – Efficiency meets international advanced standards, reducing long-term operational energy costs in steel mills

• Compact Design, High Power Density – Optimized structure layout delivers high output in a small footprint, ideal for space-constrained installations

• Low Vibration & Low Noise – Rotor is dynamically balanced with high precision; optimized electromagnetic and ventilation design ensures smooth and quiet operation

• Large Temperature Margin & Long Service Life – Class F insulation system strictly controls temperature rise, ensuring reliable long-term operation in high-temperature steel mill environments

• Modular Design – High parts interchangeability reduces inventory requirements, lowers maintenance costs, and simplifies inspection and repair

• Integrated Cooling System – Equipped with an air-to-water cooler for efficient heat dissipation in high-dust steel plant environments

• High Reliability Insulation – Winding impulse withstand voltage up to 23KV, providing ample insulation margin for high-voltage VFD applications
