Oil-free centrifugal blade compressor and magnetic-gas bearing thereof
A magnetic-gas bearing disposed in a compressor is provided. The magnetic-gas bearing includes an axis, multiple magnetic elements, multiple magnetic coils and a static pressure gas restrictor. The magnetic elements encircle the axis, and each magnetic element has two ends wound around by the magnetic coils respectively, such that the two ends of each magnetic element form a first magnetic pole and a second magnetic pole respectively. The static pressure gas restrictor encircles the axis and has a jet opening, such that the gas pass through the jet opening to form a gas-film between the static pressure gas restrictor and the axis. Besides, an oil-free centrifugal blade compressor including the magnetic-gas bearing mentioned above is also provided.
