摘要： Rotor construction that comprises rotor a centrally located permanent magnet section having aligned magnet segments having a central hole throughout its length. A thin rod of magnetic steel is located in this central hole to support the permanent magnets from within. At each end of the rod are located threaded sections for attachment to supporting end stubs. A high strength steel sleeve is interference fit over both the magnets and the end stubs to provide a mechanical link from stub to stub. The guide rod insures that the end stubs and central magnet are concentric during initial processing, prevents relative motion between the rotor components and provides support for the magnet once the sleeve is installed.

摘要： Method and apparatus for containing and protecting the magnets of a permanent magnet rotor spinning at high speeds without the use of a sleeve and is applicable to all permanent magnet rotors with two or more poles. Magnetic pole pieces are used to mechanically retain the magnets as well as provide a low reluctance path for the magnetic field to travel. The pole pieces and magnets are oriented radially on a hub made of a non-magnetic material such that the flux path of the magnets to the rotor poles is not shorted through the hub or shaft. The rotor poles have a taper angle and are secured to the rotor hub; the pole taper angle trapping the magnets, which have a matching taper angle. End cap pieces are provided to retain the rotor poles and the permanent magnets as an integral magnets/poles subassembly for use in a motor or generator.

摘要： APPARATUS AND PROCESS FOR THE PRODUCTIN OF CONTINUOUS LENGHTHS OF CARBON FIBERS OF HIGH STRENGTH AND HIGH YOUNG''S MODULUS FROM FIBERS OF ORGANIC POLYMER MATERIAL. THE APPARATUS COMPRISES A SUPPLY SPOOL FOR THE POLYMER FIBER, BRAKE MEANS FOR THE SUPPLY SPOOL, AND OXIDIZING OVEN INCLUDING MEANS TO SUPPORT AND DRIVE THE FIBER THROUGH THE OVEN AT A PRE-DETERMINED RATE AND TO HOLD THE FIBER TAUT TO CONTROL ITS LENGTH, TAKE-UP MEANS TO COLLECT THE OXIDIZED FIBER FROM THE OVEN, DRIVE MEANS FOR THE TAKE-UP MEANS, A CARBONIZING FURNACE FOR CARBONIZING THE OXIDIZED FIBER, A SUPPLY SPOOL FOR SUPPLYING OXIDIZED FIBER TO THE CARBONIZING FURNACE, AND TAKE-UP MEANS FOR COLLECTING CARBONIZED FIBER FROM THE CARBONIZING FURNACE. A PROCESS FOR THE PRODUCTION OF THE CARBON FIBER COMPRISES OXIDIZING THE POLYMER FIBER IN THE OXIDIZING ATMOSPHERE OF AN OVEN THROUGH WHICH THE FIBER IS PASSED, HOLDING THE FIBER UNDER TENSION THROUGHOUT THE OXIDIZING STEP SUCH THAT THE FIBERS DO NOT SHRINK, CONTINUING OXIDATION FOR A TIME SUCH THAT SUBSTANTIALLY COMPLETE PENETRATION OF OXYGEN IS ACHIEVED THROUGHOUT THE FIBER, AND CARBONIZING THE OXIDIZED FIBERS BY PASSING THE FIBERS FROM A SUPPLY SPOOL THROUGH A FURNACE IN WHICH THE FIBER IS CARBONIZED IN A NON-OXIDIZING ATMOSPHERE, THE FIBERS BEING PERMITTED TO SHRINK DURING THE CARBONIZATION STEP.

摘要： A vacuum pump has a back-up bearing assembly for allowing its rotor to spin down safely without damaging the pump if the primary bearing system becomes disabled. The drive shaft of the rotor is tubular and contains the back-up bearing assembly in its hollow interior. Back-up bearings are mounted onto a tubular center shaft which is coaxial with and inside the drive shaft. An axial position sensor is nested inside the center shaft and light emitted from its light emitter is reflected by a reflective target inside the drive shaft to detect the relative axial position of the drive shaft with respect to the center shaft. A polymer sleeve is attached to the end of the drive shaft as a thermal compensator, which restricts the axial movement of the drive shaft.
