On December 23, the China Machinery Industry Federation and the China General Machinery Industry Association jointly organized a new‑product appraisal meeting to evaluate two domestically‑developed high‑end motor products independently developed by Shanghai Electric Group Shanghai Electric Machinery Co., Ltd. (hereinafter referred to as “Shanghai Electric Machinery”). Following development reports, document review, Q&A and defense sessions, the expert panel reached the appraisal conclusion: the two new products feature rational design, excellent performance and independent intellectual property rights. They fill domestic technical gaps, their main technical indicators have reached the advanced level of similar international products, and they are ready for mass production. This marks a major breakthrough for Shanghai Electric in high‑end motor equipment, delivering core equipment support for safeguarding national industrial security and advancing the green and low‑carbon transition of industry.

10,000‑rpm Ultra‑High‑Speed Motor Empowers Green Upgrade of High‑Energy‑Consuming Industries

In the “steam‑to‑electricity” conversion project for the nitric‑acid “four‑in‑one” compressor unit of Ningxia Runxia Company, the domestically‑pioneered 5,600 kW ultra‑high‑speed direct‑coupled motor developed by Shanghai Electric Machinery achieved successful startup on the first attempt and passed a 72‑hour continuous stable‑operation test. It represents a milestone “from 0 to 1” breakthrough for China in 10,000‑rpm high‑capacity electric‑drive technology.

With advancement of the carbon peaking and carbon neutrality goals, green transition of traditional high‑energy‑consuming sectors such as the nitric‑acid industry has become urgent, and the “steam‑to‑electricity” retrofit for nitric‑acid “four‑in‑one” compressor units is an irresistible trend. As the core equipment of the ultra‑high‑speed direct‑coupled electric‑drive compressor unit, Shanghai Electric Machinery’s 5,600 kW ultra‑high‑speed direct‑coupled motor delivers high‑capacity output and ultra‑high rotating speed at the 10,000‑rpm level. Its successful commissioning not only provides key equipment for high‑energy‑consuming industries including nitric‑acid to shift from conventional steam drive to high‑efficiency electric drive and sets an important demonstration for energy conservation, carbon reduction and green transition of China’s nitric‑acid industry, but also substantially cuts production energy consumption and carbon emissions through remarkable improvement in system energy efficiency, opening up a practical technical path for industries across all sectors to achieve the carbon peaking and carbon neutrality goals.

Domestication Breakthrough for Supporting Motors of 100,000‑Grade Air‑Separation Units Safeguards National High‑End Equipment Industrial Security

Large‑scale air‑separation units serve as cornerstones for steel, chemical, energy and other industries. Domestic breakthroughs in their supporting motors play an extremely vital role in realizing technological independence in this field. Shanghai Electric Machinery has successfully manufactured a high‑capacity synchronous motor with a power rating of 48,600 kW for the electric‑drive unit of Shenhua Baotou’s 105,000‑Nm³/h air‑separation plant. The motor has completed type tests, with all performance indicators reaching internationally advanced standards.

The successful implementation and appraisal of this project fully proves that Shanghai Electric Machinery has acquired comprehensive capabilities for researching and manufacturing extra‑large, high‑performance motors adapted to complex operating conditions. It will effectively reverse the long‑term monopoly held by imported brands in the large‑scale air‑separation electric‑drive sector, and offer critical assurance for the security and independent controllability of high‑end equipment in national strategic industries including energy, chemical engineering and metallurgy.

The two newly‑appraised products focus respectively on two high‑end electric‑drive technical dimensions: ultra‑high rotating speed and ultra‑large capacity, demonstrating Shanghai Electric’s profound technical accumulation and innovation capacity. Their successful application and verification not only raise China’s equipment independence level in key sectors such as chemical engineering and air separation, but also provide replicable and promotable technical demonstrations and product options for promoting high‑efficiency green electric‑drive substitution in more industrial fields including oil‑gas, power and metallurgy.

Looking ahead, Shanghai Electric will further deepen R&D and innovation in high‑efficiency, green and high‑end motor equipment, continuously make breakthroughs in key core technologies, and inject stronger and independent impetus into the upgrading and green low‑carbon transition of China’s industrial equipment.
