摘要： A turbine-generator device for use in electricity generation using heat from industrial processes, renewable energy sources and other sources. The generator may be cooled by introducing into the gap between the rotor and stator liquid that is vaporized or atomized prior to introduction, which liquid is condensed from gases exhausted from the turbine. The turbine has a universal design and so may be relatively easily modified for use in connection with generators having a rated power output in the range of 50 KW to 5 MW. Such modifications are achieved, in part, through use of a modular turbine cartridge built up of discrete rotor and stator plates sized for the desired application with turbine brush seals chosen to accommodate radial rotor movements from the supported generator. The cartridge may be installed and removed from the turbine relatively easily for maintenance or rebuilding. The rotor housing is designed to be relatively easily machined to dimensions that meet desired operating parameters.

摘要： The present invention relates to a self-bearing step motor, and more particularly, to self-bearing step motor system and a control method thereof, wherein a rotor can be supported by magnetic force without adding an additional winding for supporting the rotor to a step motor having no mechanical bearing for supporting the rotor. The self-bearing step motor system of the present invention comprises a self-bearing step motor including a rotor having a plurality of rotor teeth, a stator having a plurality of stator teeth, a plurality of separate windings wound respectively around the plurality of stator teeth, and a plurality of sensors for measuring geometric deviation of the rotor; and a controller which transforms a torque current for causing the rotor to rotate and control currents for performing a bearing function of supporting the rotor into predetermined supply currents capable of generating magnetic force for allowing the rotor to be supported while causing the rotor to rotate in accordance with outputs of the sensors and position angles of the plurality of windings, which are fed back to the controller, and simultaneously distributes the supply currents among the plurality of windings grouped so that the same phase currents can be supplied thereto. According to the present invention, the self-bearing step motor can replace the conventional step motor. In particular, owing to advantages of the magnetic levitation technology, the self-bearing step motor can be used semipermanently even in a severe environment needed for a super clean and vacuum system without maintenance thereof. Thus, a wide industrial application thereof can be obtained.

摘要： A magnetically levitating motor includes a rotor that is formed from a magnetic material and has a permanent magnet attached along a circumference thereof, and a stator core section having a first stator coil that generates a levitation control magnetic flux that controls levitation of the rotor in a radial direction and a second coil that generates rotational magnetic flux against the rotor. In one aspect of the present invention, a rotor side thrust bearing magnetic path section is formed on the rotor, and a stator side thrust bearing magnetic path section that is disposed opposite in the radial direction to the rotor side thrust bearing magnetic path section is provided on the stator. A bias magnetic flux that forms the radial levitation control magnetic flux is formed to pass a gap in the radial direction between the rotor side thrust bearing magnetic path section and the stator side thrust bearing magnetic path section. A thrust control coil that generates a supporting force to support the thrust bearing load is disposed in the bias magnetic flux that forms the radial levitation control magnetic flux, wherein the thrust control coil is wound about a rotational axis with respect to one of the rotor side thrust bearing magnetic path section and the stator side thrust bearing magnetic path section.
