Abstract:
A system includes an electrodynamically suspended seal. The electrodynamically suspended seal includes a first element that includes an electrically conducting material and a second element that includes a magnetic material. At least one of the first and second elements is configured to rotate about an axial axis. The first and second elements are disposed adjacent one another. The rotational movement of at least one of the first and second elements creates a levitation force such that the first and second elements are repelled away from one another. The electrodynamically suspended seal also includes a third element configured to create a counteracting force.
