• Development and analysis of trapped field magnets in electromechanical devices 

      Davey, K.; Wienstein, R.; Sawh, R. (, undated)
      High temperature superconducting trapped field magnets (TFM) offer great potential as an alternative to 2>d generation YBCO wire, both in cost and performance. Attention is given to the calculation of current distribution ...
    • Dynamic Load and Storage Integration 

      Hebner, R. E.; Davey, K.; Herbst, J.; Hall, D.; Hahne, J.; Surls, D.; Ouroua, A. (IEEE, undated)
      Modern technology combined with the desire to minimize the size and weight of a ship’s power system are leading to renewed interest in more electric or all electric ships. An important characteristic of the emerging ship ...
    • Flywheel energy storage system with homopolar electrodynamic magnetic bearing 

      Filatov, A.; McMullen, P.; Davey, K.; Thompson, R.C. (, undated)
      The goal of this research was to evaluate the potential of homopolar electrodynamic magnetic bearings for flywheel energy storage systems (FESSs). The primary target was a FESS for Low Earth Orbit (LEO) satellites; however, ...
    • HTS Trapped field magnet based motors for naval applications 

      Davey, K.; Weinstein, R. (2006-05)
      As the Navy conve1is to all electric ships, it is investigating ways to reduce the size and weight of electric propulsion motors. The fundamental challenge is to achieve high torque and low speed in a small motor. To achieve ...
    • Magnetic gears – an essential enabler for the next generation’s electromechanical drives 

      Davey, K.; Werst, M.D; Wedeking, G.A. (2008-08)
      New magnetic gears show promise as replacements for mechanical gears, not only because of high reliability and low maintenance, but also because of superior torque-to-weight ratios. A superior torqueto- weight ratio is ...
    • Optimal power generation scheduling of a shipboard power system 

      Wu, W.; Wang, D; Arapostathis, A; Davey, K. (IEEE, 2007-05)
      This paper studies the optimal power generation scheduling for a shipboard power system. The problem is formulated as a discrete-time Markov Decision Process (MDP). The paper considers the shipboard power system both without ...
    • Power Grid for a Naval Electric Ship - AC versus DC 

      Davey, K.; Hebner, R.E. (, undated)
      The debate over the best electric grid topology for an all electric ship has provoked discussion on a wide range of topics, spanning interconnection issues, transmission losses, and power preferences of electronic components, ...
    • Radial Flux High Temperature Superconductor Motor using Bulk Trapped Field Magnets 

      Feng, X.; Gao, G.; Davey, K.; Werst, M.; Hebner, R.; Weinstein, R.; Parks, D.; Sawh, R. (IEEE, 2009-05)
      This team has designed, built, and successfully run a radial flux high temperature superconductor (HTS) trapped field magnet (TFM) motor. The motor was run in a zero field cooled mode. This paper conveys several lessons ...
    • Reconfiguration in shipboard power systems 

      Davey, K.; Longoria, R; Shutt, W; Carroll, J; Nagaraj, K; Park, J; Rosenwinkel, T; Wu, W; Arapostathis, A. (2007-07)
      A shipboard power system is self contained, tightly coupled, and small enough to allow nearly real time state estimation, given the right equivalent circuit representations. Redirecting power flow is the preeminent task ...
