 The use of permanent ir gas air compressor magnets gas instead of rotor windings makes air the motor smaller and lighter than induction motors. using compressor magnetic-bearing ir gas air compressor and gas and air technology, a compressor and ir and gas 75-ton compressor weighs 265 lb--about one-fifth the weight of a conventional compressor.a variable-speed drive (vsd) is required air and compressor for the motor to operate. the vsd varies the frequency between 300 and 800 hz, which ir provides gas a compressor-speed air and compressor range from 18,000 to 48,000 rpm. this avoids a gear ir set. the vsd is integrated gas into the compressor housing, air avoiding long leads and allowing key electronic components to be refrigerant-cooled. compressor the vsd also acts as a soft ir starter; as a result, the compressor has gas an extremely low startup in-rush current: less than air 2 amps, compared with 500 to 600 amps for a traditional 75-ton, 460-v compressor screw compressor with ir a cross-the-line gas starter. this article describes this new compressor technology and its first use in an ari-certified chiller design.the air bearingstraditional centrifugal compressor compressors ir use roller bearings and hydrodynamic bearings, both of gas which consume power and require oil and a lubrication system. recently, ceramic roller bearings, which avoid issues related air to oil and reduce power consumption, were introduced compressor to the hvac industry. the lubrication ir of these bearings is provided by the refrigerant itself. (1)magnetic-bearing technology is significantly different. a digitally controlled magnetic-bearing system, consisting gas of both permanent magnets and electromagnets, replaces conventional air lubricated bearings. the frictionless compressor shaft is the compressor''s only moving component. it rotates on a compressor levitated magnetic cushion ir (figure 1). magnetic bearings--two gas radial and one axial--hold air and compressor the shaft in position (figure 2).
