Abstract
A magnetic suspension device comprising an annular stator surrounded by a coaxial annular rotor with an annular gap therebetween. The rotor comprises an axial ring-like permanent magnet for creating the suspension magnetic field. The stator comprises a ring-like U-shaped section of a magnetic material with an axial ring portion and a pair of parallel radial annular portions, the axial ring portion including segmental coils for producing positioning control magnetic fluxes for radial positioning of the rotor relative to the stator. The mode of construction of the stator considerably facilitates the fabrication and assembly of the device and provides a more efficient operation than the known devices.
