"Superconducting motors are new types of AC synchronous motors that employ HTS (high temperature superconductor) windings in place of conventional copper coils. Because HTS wire can carry significantly larger currents than can copper wire, these windings are capable of generating much more powerful magnetic fields in a given volume of space."
