In the Permasyn motor for submarines, excitation is achieved with permanent magnets. This results in outstanding features in terms of uncompromising reliability and operational readiness, combined with high efficiency and extremely low signature values. The replacement of the electrical exciter by a permanent magnet possible enables extremely small and lightweight motors with high power density and high torque over the entire speed range. This enables the use of a  larger propeller with significantly higher efficiency.

Permasyn from Siemens - the solution for special challenges:

  • Permasyn features ultracompact construction thanks to integrated IGBT converter technology

  • Extremely low signature values

  • Low weight and high energy efficiency for longer submerged operation

  • Low heat emission, simplified electromagnetic shielding

  • Electronic speed regulation without torque-free shift intervals, switching noise, or high current peaks
