Abstract: An exemplary embodiment of the invention is a method for a standardized collaborative engineering. The method includes representing design information in a standard transmission format at a client and uploading the design information in the standard transmission format to a server. The server receives the design information in the standard transmission format and converts the design information in the standard transmission format to design information in a product data management format. The server stores the design information in the product data management format.

Abstract: An exemplary embodiment of the invention is directed to a method for performing quality function deployment for a system having a plurality of levels. The method includes obtaining a plurality of first level critical to quality parameters and obtaining a plurality of first level key control parameters. A first level quality matrix is generated identifying an effect at least one first level key control parameter has on at least one first level critical to quality parameter. The first level key control parameters are arranged into a first group and a second group. A second level quality matrix is generated for the first group. The second level quality matrix includes second level critical to quality parameters corresponding to the first group of first level key control parameters and a second level key control parameter. The second level quality matrix identifies an effect said second level key control parameter has on at least one second level critical to quality parameter.

Abstract: An exemplary embodiment is a system and method for performing engineering design. The system includes a client for receiving first design information from a first source. The system also includes a server coupled to the client via a network. The client uploads the first design information to the server, and the server determines whether the first source has authorization to submit the first design information, notifies a second source of the first design information and transmits the first design information to the second source. The server stores the design information.

Abstract: A rotor for use in a line start permanent magnet motor comprises a rotor core having a shaft and including teeth defining slots; a rotor cage, at least a portion of which extends through the slots; and a layer of composite permanent magnet material at least partially coating the rotor core.

Abstract: A motor stator comprises a first stator frame part, a second stator frame part including first and second pole portions separated by a stator bridge, and two magnetic arms. Each of two bobbins is wound with a coil and situated on a respective one of the arms. The first and second stator frame parts are coupled by the arms so as to leave an opening between the two bobbins and the first and second frame parts for insertion of a rotor.

Abstract: A magnetic thrust compensator for a mechanical thrust bearing includes a parallel operating axial magnetic bearing including a stator including two parallel stator extensions, a rotor disk situated between the two stator extensions, and first and second electromagnets each situated on a respective stator extension and facing the rotor disk. A controller selectively energizes one of the electromagnets. Additional stator extensions and rotor disks can be used to provide fault tolerance. The electromagnets can each include dual annular windings. The compensator can include an additional stator extension, an additional rotor disk, and bias magnet situated on the additional stator extension and facing the additional rotor disk with the controller being adapted to selectively supply current to the bias magnet.

Abstract: An apparatus and method for estimating rotor position in and commutating a switched reluctance motor (SRM), using both a flux/current SRM angle estimator and a toothed wheel generating a magnetic pickup. Commutation is based on the flux/current SRM at startup and lower speeds. At higher speeds, when magnetic pickup sensed from the toothed wheel is sufficiently large in amplitude to create frequent reliable interrupts, commutation is based on signals from the toothed wheel magnetic pickup. Phase errors can be compensated by adjusting the angle input to the commutator as a function of estimated speed. Alternatively, the flux/current SRM angle estimator can be run in a background mode to tune the toothed wheel interrupt angle signal at different speeds.

Abstract: An axial magnetic thrust bearing stator includes a plurality of laminated cores. Each of the cores is magnetically conductive, situated in a common plane, and symmetrically situated about a center of rotation. A plurality of electrically conductive coils are provided with each coil situated at least partially in a respective one of the cores.
