The present disclosure provides a method and system for measuring increase in wattage to detect a potential winding failure. The increase in watts in the winding occurs when a time-varying magnetic field from active turns of the winding induces a time-varying current on shorted turns of the winding. The resistance through the shorted turns and the induced current result in power usage and increased watts. The wattage increase is much greater than a resistance decrease in the winding by the shorted turns. Measuring the watts results in detecting a shorting winding with greater sensitivity than measuring the resistance. In one embodiment, the winding can be tested offline with a wattmeter and power supply. In another embodiment, the winding in use and its wattage can be monitored continuously or periodically locally or remotely, with an optional sensor to initiate a signal upon reaching a certain percentage increase in watts.

A rotor for a permanent magnet machine comprises first and second axially successive rotor sections (102, 103) each comprising permanent magnets generating magnetic field having a pole pitch (pp). The rotor comprises a first coupling system (106) for connecting the first rotor section to a shaft (1 15) and a second coupling system (1 19) for connecting the second rotor section to the shaft or to the first rotor section. The second rotor section is rotatable with respect to the first rotor section by an angle corresponding to the pole pitch in response to releasing the second coupling system so as to set the stator flux-linkages generated by the first and second rotor sections to be substantially zeroes. Thereafter, the permanent magnets do not substantially induce voltages on the stator windings even if the rotor is rotating during for example an internal fault of stator windings.

The present disclosure provides a high flow coefficient spool valve (50) through one or more changes in the flow path from a conventional spool valve. The body (56) of the spool valve includes spherically contoured internal grooves (68). The spool (58), slidably engaged inside the body (56), includes concave surfaces between seals (62) that is complementary to the spherically shaped internal grooves (68) of the body. The spherical shape of the body internal grooves (68) and/or concave shape of the spool allow more volume and more laminar flow therebetween, resulting in an increased flow coefficient and flow capacity. The body also is formed with transverse port windows in the port that contour into a bore of the body adjacent the spool. A choke volume in the flow is strategically designed in a parallel flow location rather than a perpendicular flow location to promote laminar flow and lessen turbulence to also increase the flow coefficient.

A solenoid coil assembly for hazardous environments comprises a solenoid coil and an enclosure entirely filled with encapsulation material. The encapsulation material leaves zero or almost zero volume in the enclosure for hazardous material to accumulate in any amount that could explode. This allows the solenoid coil assembly to be constructed without the usual industry standard flame paths. Additionally, the enclosure may be made of physically rigid and strong material such as metal or the like to better withstand harsh and corrosive conditions within hazardous environments without being explosion proof. The walls of such an enclosure need only have a moderate thickness and weight relative to enclosures that are explosion proof, as there is no meaningful risk of an explosion occurring within the enclosure. The combination of a rugged exterior and a zero-volume interior allows the solenoid coil assembly to reduce weight and cost while providing superior environmental protection.


Grant
Agency: European Commission | Branch: H2020 | Program: SGA-RIA | Phase: GEANT-CABLE-2015 | Award Amount: 12.45M | Year: 2016

The BELLA-S1 proposal aims to provide for the long-term interconnectivity needs of the European and Latin American research and education networks, and answers the call for transatlantic connectivity to Latin America in the H2020 Work Programme 2014-15. The objective will be to strengthen connectivity to Latin America ensuring very high capacity, cost benefits and the shortest possible route, whilst stimulating diversity over the transatlantic segment. The objective will be met in two phases: phase one will procure an indefeasible right of use for a portion of the spectrum of a direct submarine telecommunications cable between Europe and Latin America; phase two will deploy one or more wavelengths, as required, on the spectrum procured to interconnect the GANT and RedCLARA networks, and provide for the intercontinental connectivity needs of the European and Latin American research and education communities.

The overall objective is to provide a stable environment for the implementation of GANT as the European Communications Commons for the European Research Area, which will provide the best possible digital infrastructure to ensure that Europe remains in the forefront of research. GANTs extensive and long-standing contacts with large data disciplines such as biology, radioastronomy and high-energy physics help shape the evolution of the networking facilities required. This is complemented by partner contacts with research domains that are new users of high-performance networks and services, such as: digital preservation, real-time art and humanities. The vision is to position the GANT partnership optimally to achieve the strategic objectives of the FPA while ensuring the continuity and improvement of the services successfully offered under the GN3plus FP7 project. The extensive experience of the GANT partnership in providing high-quality and innovative services has been applied to the preparation phase of this proposal. The following GN4-1 work package objectives deserve to be highlighted: Maintain and enhance the production service and achieve cost reductions without negative effects on network service levels. Coordinate with the other European e-infrastructure efforts both individually and in the framework of the increased coordination effort. Prepare a new round of Open Call projects to start immediately after the end of the GN4-1 project. Expand the footprint and the depth of services offered to roaming users with enhanced trust and identity services through Federation as a Service and with group and attribute management added to eduGAIN. Develop online real-time services to improve the ease and function of videconferencing, open learning support and general multimedia use. Review the existing service catalogue using the Product Lifecycle Management process to assess the cost/benefits of each carefully to define the future service strategy.

GN4-2 is the proposed project for the second Specific Grant Agreement under the 68-month Framework Partnership Agreement (FPA) established between the GANT Consortium and the European Commission in April 2015.This second phase of implementing the FPA will raise European research to the next level by promoting scientific excellence, access and re-use of research data. It will also drive European-wide cost efficiencies in scientific infrastructure by promoting interoperability with other e-infrastructures on an unprecedented scale. The FPA objective for the GANT Partnership is to contribute to effective European research by making Europe the best-connected region in the world. GANT must offer European researchers the network, communications facilities and application access that ensure the digital continuum necessary to conduct world-class research in collaboration with their peers, regardless of geographical location. GANT will maintain the operational excellence of the established GANT services, while achieving economies on the costs of the backbone network. The reliable, secure and state-of-the-art network services offered to researchers and other network users across Europe will remain exceptional. Massive data-transfer capacities required by extreme-scale instruments and by the penetration of big data in many areas of science will be prototyped with due consideration to the specific security and deployment challenges. Trust and identity is also prioritised with the introduction of a scalable operational model and with user requirements addressed in close concertation with the AARC and proposed AARC2 projects. GN4-2 developments are also guided by the vision of a future where a set of coherent and integrated European e-infrastructure services will offer convenient, seamless access for end-users through a common service catalogue, and facilitating the adoption of services offered by new e-infrastructure developments, such as the European Open Science Cloud.
