China Develops Low Noise Motor for Use in Nuclear Submarine Propulsion
October 25, 2017
”The China Shipbuilding Industry Corporation (CSIS) has conducted a trial run of the country´s first permanent magnet propulsion motor which is characterized by very low noise, for potential use in nuclear submarines.”
”The new high-performance permanent magnet motors made from rare-earth materials avoid the flaws of traditional motors that work under the excitation principle and can provide much greater power density, and can significantly reduce its working noise.”

GA-EMS to develop permanent-magnet propulsion motor for US Navy LDUUV
December 21, 2017
”The US Office of Naval Research has awarded General Atomics Electromagnetic Systems a contract to design and deliver an advanced permanent-magnet propulsion motor to be used on the US Navy’s large displacement unmanned undersea vehicles (LDUUVs).”
“After completing a review of our motor’s capabilities and the applicability for undersea operations, we are very excited to take the next step to design and deliver a second-generation propulsion motor to ONR for further evaluation and eventual on-vehicle testing,” Rolf Ziesing, vice president of Programs at GA-EMS, said.
