Abstract: The invention relates to improvements in compressors and in particular to arrangements for driving screw compressors by reluctance drive motors. A screw compressor assembly is provided for compressed gas comprising a screw compressor having a casing (16) and at least one pair of intermeshing helically formed screw rotors (11,12) each of which is mounted on a rotor shaft rotatably mounted within the casing by means of bearings (15). Said assembly further comprises a switched reluctance motor comprising a stator (18) attached to the casing and a rotor (19) mounted on one of the motor shafts such that one of the screw rotors is driven directly by the motor. The motor rotor is displaced relative to the stator by a pre-determined axial distance x) such that a resultant magnetic force is provided in an axial direction.

Abstract: The present invention relates to a rotary compressor and is concerned with that type of compressor which is of oil sealed type, that is to say the type in which oil is injected into the compression space and is subsequently removed from the compressed gas, typically air, and then refused. The rotary compressor comprises an air-end comprising a rotor disposed internally within a stator and a drive-end having a long length motor shaft extending therefrom. The shaft passes through an air-end flange to engage with a longitudinal bore extending centrally through the rotor.

Abstract: The present invention relates to a rotary compressor and is concerned with that type of compressor which is of oil sealed type, that is to say the type in which oil is injected into the compression space and is subsequently removed from the compressed gas, typically air, and then refused. The rotary compressor comprises an air-end comprising a rotor disposed internally within a stator and a drive-end being separable from said air-end and having a long length motor shaft extending therefrom. The shaft passes engages with a longitudinal bore extending centrally through the rotor and the air-end is provided with radial retention means to locate the rotor relative to the stator in the absence of the drive-end shaft.
