Design considerations for electric motors using stacks of high temperature superconducting tape as permanent magnets / Climente-Alarcon, V (Cambridge U.) ; Patel, A (Cambridge U.) ; Baskys, A (Cambridge U. ; CERN) ; Glowacki, B A (Cambridge U.)
High temperature superconducting (HTS) tape can be cut and stacked to form composite bulks capable of generating fields as high as 17.7 T, the highest of any trapped field magnet. This makes them the most powerful permanent magnets accounting for the need to maintain a cryogenic temperature. [...]

Computation of Superconducting Stacks Magnetization in an Electrical Machine / Climente-Alarcon, Vicente (Cambridge U. (main)) ; Patel, Anup (Cambridge U. (main)) ; Baskys, Algirdas (CERN) ; Glowacki, Bartek A (Cambridge U. (main) ; Inst. Power Eng., Warsaw)
Superconducting technology offers the prospect of sharply increasing power density of rotating electrical machines, especially in the low-speed, high-torque range, with impact in applications such as wind energy and aircraft propulsion. Among the enabling technologies, stacks consisting of piled up layers of high-temperature superconductors may provide a source of magnetic flux density for torque production, without the complexity of superconducting wound rotor poles.

An experimental assessment of rotor superconducting stack demagnetization in a liquid nitrogen environment / Smara, Anis (Cambridge U.) ; Mineev, Nikolay (Cambridge U.) ; Climente-Alarcon, Vicente (Cambridge U.) ; Patel, Anup (Cambridge U.) ; Baskys, Algirdas (Cambridge U. ; CERN) ; Glowacki, Bartek A (Cambridge U. ; Inst. Power Eng., Warsaw) ; Reis, Thomas (Oswald Elektromotoren GmbH, Miltenberg)
Stacks of high-temperature superconducting tape have proved to trap in laboratory conditions levels of magnetic flux density one order of magnitude above actual state-of-the-art permanent magnets. Their simple manufacturing, high mechanical properties and intrinsic resistance to sudden quench greatly facilitate their utilization in industrial applications, amongst them, as a source of magnetic flux density in the rotor of electrical machines.

Application of Hot Press Bending for Shaping a Stack of HTS Tapes Operating as a Trapped Flux Magnet / Tomkow, Lukasz (Cambridge U. ; CERN) ; Smara, Anis (Cambridge U.) ; Glowacki, Bartek A (Cambridge U. ; Inst. Power Eng., Warsaw)
Trapped-flux magnets made of stacks of superconducting tapes are an interesting and important alternative to the application of rare-earth permanent magnets and trapping flux in bulk superconductors. Many applications, such as electric motors, can require the complex shapes of magnetic elements to combat issues such as demagnetization during the operation. [...]
