Foil gas bearings enable oil-free compressor 'breakthrough'
Mohawk Innovative Technology, Inc. (MiTi) has enabled what it claims is a truly oil-free plant air compressor. Working with Samsung Techwin Co., Ltd., MiTi applied its proprietary compliant foil gas bearing design to support a 25-lb. rotor with integral permanent magnet motor on two radial bearings.
A double-acting thrust bearing controls both axial thrust and the tip clearance of an impeller overhung on each end. Fig. 1 shows an isometric view of the Turbo-Master Micro TM Series compressor line. Units are rated at 125, 150 or 175 hp.
