The motor used in conventional submarines has the power of several megawatts, but he still cannot determine the exact power of the installed test model.

Permanent magnet propulsion motor technology can replace the reduction gears and significantly reduce the running sound to the lowest possible level, the expert said.

On the global scale, the permanent magnet motor will have the power to meet the needs of full electrical movement for nuclear submarines.

In July 2017, Chinese state media had reported that the China is fitting its newest nuclear sub with an electromagnetic engine that sounds a lot like Tom Clancy's fictional Red October engine.

They had also reported that an electric rim driven shaftless submarine propulsion system was installed.

Rear Admiral Ma Weiming, China's top naval engineer, is notably responsible for the development of multiple Chinese naval electromagnetic programs, including the electromagnetic catapult and railguns. He said the Chinese navy is adding a "shaftless" rim-driven pumpjet, a revolutionary and silent propulsion system to their newest attack submarine, the Type 095 SSN.
