Engineering360: "Festo Builds a Superconductive Motor"

Perhaps detailed photos or an exploded view showing internal parts are trade secrets, but we didn't get any kind of idea of motor construction or operating principles. Unless I missed it, they did not say if the motor operates from an AC or DC source, or if it's brushless, inductive, or what??

I am interested and would like to learn more.

Thank you,
