Today, the first batch of five oilfield motors from China North Locomotive Group's Yongji Motor Factory has been successfully shipped to a rig manufacturing plant, marking a significant milestone in the export of Chinese oilfield motor-driven rigs to North America. This is the largest shipment to date, signaling a growing presence of Chinese technology in the global energy sector.
It was reported that in June this year, Yongji Motor Factory received an order to export 129 sets of oilfield motors to North America. These are AC variable frequency motors developed after eight years of independent research and development. They represent a major advancement in China’s AC and DC oilfield motor technology, showcasing the country’s increasing technical capabilities in this critical area.
Oil rigs are highly complex and large-scale equipment used for drilling oil and natural gas in various environments, including deserts and oceans. They require advanced engineering and are expensive to produce. The transmission system of an oil rig is a key indicator of its technological sophistication. Electric drive systems are currently considered the most advanced, and the United States remains a global leader in the production of complete oil rigs. China is among the few countries capable of manufacturing such comprehensive systems.
Historically, China's oilfield drilling rigs relied on foreign brands for their electric drive systems. However, in 1998, Yongji Motor Factory, a leading domestic company in locomotive traction motor technology, entered the oilfield motor market through innovation. This move helped fill a critical gap in China’s oilfield motor industry.
Following this, the YZ08 series DC motor was developed using internationally recognized manufacturing techniques and advanced insulation structures. It offers high efficiency, reliability, and versatility, with installation dimensions matching those of imported motors. These features have allowed it to replace over 70% of imported electric motors in China’s oilfields, effectively ending the long-standing reliance on foreign products.
This achievement not only highlights China’s growing technological independence but also demonstrates the potential for Chinese manufacturers to compete globally in high-tech industrial sectors.
