Propeller Motors for Submarines

Apart from providing electrical equipment for surface vessels, Siemens also equips a range of submarines with DC propeller motors as well.

The PERMASYN motor remarks our latest development in the field of submarine propulsion. The advanced synchronous motor with permanent-field excitation is specially designed for submarines.

PERMASYN motors feature extreme low noise levels, high efficiency as well as small volume and weight.

PERMASYN is to be determined as the propulsion motor for the latest generation of submarines class 212 of the German and the Italian Navy. This propulsion concept for air independent propulsion (AIP) comprises the PERMASYN motor in addition with most modern fuel cell technology as primary power supply.
