Yougu Electric Enters a New Phase of Small‑Batch Production | First Marine Permanent‑Magnet Motor Rotor Successfully Rolls off the Production Line and is Delivered
Recently, Yougu Electric Technology (Changzhou) Co., Ltd. (hereinafter referred to as “Yougu Electric”) has successfully delivered high‑performance permanent‑magnet rotors for MW‑class marine shaft‑driven generators to Hyosung of South Korea. As the first major delivered project marking Yougu Electric’s official entry into the small‑batch production phase, this delivery represents a milestone of the company’s small‑batch manufacturing capability. It also signals a key breakthrough in the production of core components for high‑end marine equipment, adding a vital growth driver for competition in the global energy and shipbuilding industries.
The delivered product is a high‑performance marine permanent‑magnet motor rotor weighing 5,600 kg with dimensions of 2000 mm × 2000 mm × 1000 mm. Its manufacturing and assembly posed substantial challenges. On one hand, high‑grade magnetic steel is adopted for magnetic poles, generating extremely strong magnetic attraction among components and bringing great difficulties to assembly processes. On the other hand, the project requires dynamic balance accuracy of Grade G0.4, far exceeding conventional industry standards, which makes the tedious dynamic‑balance correction procedures in traditional processes even more demanding.
Rising to these challenges, Yougu Electric leverages world‑class manufacturing strengths and top‑tier R&D teams to focus on technological innovation and process optimization. Through the coordinated application of core technologies including precision positioning, intelligent assembly and multi‑stage dynamic‑balance correction, the company achieves precise fitting of magnetic‑pole assemblies and ultra‑high‑precision dynamic balance. It effectively guarantees the stability and reliability of rotors under high‑speed operation, fully meets stringent standards in the marine power sector, and lays a solid foundation for smooth product delivery.
The product will be applied to MW‑class marine shaft‑driven generators manufactured by Hyosung, a renowned South‑Korean enterprise, supporting green shipping and efficient energy conversion. This delivery marks Yougu Electric’s first foray into the manufacturing and assembly of permanent‑magnet rotors for marine shaft‑driven generators. It fully demonstrates the company’s outstanding capabilities in assembling large‑size, heavy‑weight structural components with strong magnetic forces, and validates its core competitiveness in the international high‑end manufacturing market.
As the landmark achievement of Yougu Electric’s small‑batch production phase, this delivery strongly validates the company’s previous technological accumulation and process optimization. It also proves that Yougu Electric is capable of translating high‑end manufacturing expertise into stable and efficient small‑batch output, laying a solid groundwork for future mass‑production and delivery of generator core components and other high‑end equipment.
Yougu Electric’s breakthrough is backed by robust technical support from its parent company, Changzhou Yougu New Energy Technology Co., Ltd. Drawing on the parent firm’s core strengths of “first‑class culture, first‑class team, first‑class management, first‑class technology and first‑class equipment”, Yougu Electric keeps forging ahead steadily in high‑end manufacturing.
