Abstract
An installation for the drive and support of a disc-shaped rotor. The installation for the drive and for the bearing support of a disc-shaped rotor incorporates a constructional element for the magnetic, and particularly electromagnetic, support and drive, which annularly encompasses the rotor in a ring-like configuration, wherein the magnetic support serves primarily for absorption of the radial forces, and that the installation encompasses an aerostatic and/or aerodynamic bearing support for primarily absorbing or receiving the axial forces, and whose rotating portion forms an integral unit with the rotor.
Claims11
In combination, a disc-shaped rotor and a frame surrounding said rotor, said rotor having upper and lower radial surfaces and a peripheral surface, unitary means supported by said frame for magnetic bearing support and drive of said rotor, a plate facing said lower surface of the rotor and means coupled with said plate for producing a gas cushion for axial support of said rotor, said means for producing the gas cushion comprising at least one closable conduit having an end facing said lower surface of said rotor, said unitary means comprising a common annular coil system surrounding said rotor and disposed exactly opposite the rotor for effecting rotary drive of said rotor while suspending said rotor by magnetic effect independently of the gas cushion producing means and with the conduit closed, said conduit being openable during rotation of said rotor for applying a braking effect on said rotor.
