China Marks a Milestone in Maritime Might, Successfully Tests First Submarine Permanent Magnet Motor China Marks a Milestone in Maritime Might, Successfully Tests First Submarine Permanent Magnet Motor

(Yicai Global) Oct. 24 -- China recently tested its first proprietary submarine-based permanent magnet propulsion motor and the test proved successful, laying a solid foundation for future tests, per news China Shipbuilding Industry Corp. released yesterday.

The first submarine-based permanent magnet motor, developed by No. 712 Research Institute of China Shipbuilding Industry Corp., successfully withstood testing on the morning of Oct. 18, with all performance indicators meeting technical requirements.

The country owns the full intellectual property rights to the new propulsion device.

Modern submarine-based permanent magnet motors are a relatively recent technology first applied in the 1980s. It uses high-performance permanent magnet materials made of rare earth materials to replace the excitation mechanism of traditional DC motors, providing the advantages of high-power density and low noise levels. The inception of China's development of permanent magnet motors in the 1990s was emblematic of the country's bourgeoning oceanic power.
