active magnetic bearing造句

• Kasarda reviews the history of active magnetic bearings in depth.
• She notes that the first commercial application of active magnetic bearings was in turbomachinery.
• The French company S2M, founded in 1976, was the first to commercially market active magnetic bearings.
• The active magnetic bearing allowed the elimination of oil reservoirs on compressors for the NOVA Gas Transmission Ltd . ( NGTL ) gas pipelines in Alberta, Canada.
• As a result, most magnetic bearings are active magnetic bearings, using electromagnets which require continuous power input and an active control system to keep the load stable.
• In a combined design, permanent magnets are often used to carry the static load and the active magnetic bearing is used when the levitated object deviates from its optimum position.
• In 1987, Estelle Croot further improved active magnetic bearing technology, but these designs were not manufactured due to expensive costs of production, which used a laser guidance system.
• "' INCOR "'is an axial-flow pump for support of the left rotor in the pump has an active magnetic bearing while floating contact-free.
• Jesse Beams from the University of Virginia filed some of the earliest active magnetic bearing patents during World War II . The patents dealt with ultracentrifuges intended for the enrichment of isotopes of elements needed for the Manhattan Project.
• Starting from 1996 the Dutch oil and gas company NAM installed over a period of 10 years 20 large E-motor driven ( with variable speed drive ) gas compressors of 23 MW fully equipped with active magnetic bearings on both the E-motor and the compressor.
• Estelle Croot's research was the subject of 3 Australian patents and was funded by Nachi Fujikoshi, Nippon Seiko KK and Hitachi, and her calculations were used in other technologies that used rare earth magnets but the active magnetic bearings were only developed to the prototype stage.
• Applying active magnetic bearings in the driver and in the compressor ( compared to the traditional configuration with a gearbox, plain bearings and a gasturbine-driver ) results in a relatively simple system with a very wide operating range and high efficiencies ( particularly at partial load ).
• The motor-compressor design was done by Siemens and the active magnetic bearings were delivered by Waukesha Bearings ( owned by Dover Corporation ) . ( Originally these bearings were designed by Glacier, this company was later taken over by Federal Mogul and is now part of Waukesha Bearings . ) By using active magnetic bearings and a direct drive between motor and compressor ( without the gearbox in between ) and applying dry gas seals, a full dry-dry ( oil free ) system has been installed.
