15. Revolutionary Technology (1/3)
Superconductive and Magnetically levitated Submarine subsystems
Overview
• Compared to conventional motor, Superconducting technology allows motor to be larger
torque and more compact. These benefits would lead submarine to improvement of the Anti-
detection capability and expansion underwater time thanks to faster maximum cruse speed.
• Restriction of conventional motor due to torque constraint is required to be larger propulsion
size. In order to address this issue, “Superconducting motor” with high power density plays an
crucial role to be higher torque as well as smaller motor size.
