Propulsion electric motor for ships (asynchronous)

Siemens AG - Marine Solutions
Submarines are the vessels which depend most upon the complete reliability and operational readiness of their propulsion motors. A drive system that operates efficiently with very low signatures is essential for long dives and makes the boat harder to detect. With the Permasyn drive motor for submarines, excitation is achieved with the aid of permanent magnets allowing it to work without addtional electrical excitation. Although it is smaller and more lightweight than conventional propulsion solutions, it achieves much better efficiency at extremely low signatures.
