    Abstract: A superconductor motor (10) comprises a stator assembly (14) which includes a plurality of solenoids (40-44). A rotor assembly (12) includes a disk (20) of superconductive material in which are entrapped magnetic lines of flux which cause the rotor to function as a magnet. The lines of flux tend to creep throughout the disk over time thereby reducing the magnetic properties of the rotor assembly and decreasing motor performance. A plurality of coils (48a-48l) are carried by the disk. The stator solenoids are energized to produce rotation of the rotor, and the coils are energized in a predetermined manner to compensate for the flux creep in the disk and to restore the rotor assembly's magnetic properties thus to prevent deterioration in motor performance.

    Abstract: A rotor assembly for a permanent magnet motor includes a set of laminatings forming a rotor body, each lamination having a first magnet slot therein. A generally rectangular permanent magnet is disposed in the magnet slot, the magnet slot of each lamination being shaped so as to receive the rectangular permanent magnet through all the skewed laminations with a minimum air gap. A method of making an assembly such as a rotor includes the steps of providing an assembly body made of ferromagnetic material defining at least one magnet slot therein. The slot is at least partially filled with a mixture of magnetizable particles in a binder. The mixture is compressed and then cured to bond the magnetizable particles together in the slot and the bonded particles are then magnetized in the slot to form a magnet in situ in the slot without an air gap.

    Abstract: An improved rotor for an induction motor is disclosed. In one aspect of the disclosed invention, endshield laminations are placed on the top and bottom of a lamination stack of a rotor. The endshields have holes therein which mask the ends of the bar members within the lamination stack. The unmasked portions of the bar members are connected through the holes to connection members in such a fashion to make multiple compound short-circuit loops. Because the endshields, like the laminations generally, are not conductive, the connection members are only in contact with the bar members through the holes in the endshield, which prevents the multiple loops from shorting to one another. The bar members and connector members are preferably die-cast in and around the rotor laminations and the endshields.

    Abstract: A rotor for a two-pole synchronous reluctance or a switched reluctance motor can be constructed from a stack of flat, planar laminations of grain-oriented materials. To enhance the necessary anisotropy of reluctance, slots are provided in the lamination along the magnetic flux lines in the preferred grain direction. The laminations may be provided with an essentially circular outer perimeter, and slots for a squirrel cage winding provided. A complete, efficient squirrel cage winding can thus be provided for a two-pole synchronous reluctance motor for starting purposes.

    Abstract: A superconducting motor (1) comprises a stator (3) and a rotor (5), both of which employ superconductive windings. The rotor includes two sets of windings, a large rotor winding (13) and a small rotor winding (15). The windings are connected to form a current loop (16) which is exposed to a magnetic field. Switches (S1,S2) or diodes (D1,D2) are employed to trap a maximum number of magnetic flux lines in the loop when the magnetic field is impressed on the loop. Thereafter, the trapped flux is transferred from the small to the large winding to run the motor. When the switches are closed, the loop acts as a perfect conductor whereby no flux change occurs within the loop.
