Electromagnetic forming (EMF) is a high-speed forming process that has recently been explored in modern industrial applications to extend the forming limits of magnesium alloy or aluminum metal sheets. In this study, an experimental and statistical approach using analysis of variance (ANOVA) and response surface methodology (RSM) techniques is used to find the significant main and interaction...

High temperature superconductor (HTS) coils have been applied in high field magnet applications, such as nuclear magnetic resonance (NMR) and maglev trains. The accurate calculation on the critical current of HTS coils is key for the magnet design and optimization. In practical applications, HTS tapes are also often wound into different shaped coils, such as racetrack coil for motors and ‘D’...

Within the framework of Open Science, set as a priority by the European Commission in Horizon Europe, the OPEN Super Conducting Cable (OPENSC2) code has been recently developed and released to grant the entire research community the possibility to analyse thermal-hydraulic (TH) transients in forced-flow superconducting (SC) cables for fusion and power applications. The code is...

Recently, permanent magnet synchronous motors(PMSM) are widely used in industrial fields due to various advantages such as high speed operation, high efficiency, and compact design. However, PMSM has the disadvantage of noise and vibration caused by high magnetic energy during the interaction between the stator and the rotor magnet. These drawbacks have a significant impact on machine...

One of the problems with the practical application of high-temperature superconducting coils is burnout due to the heat generated by a local low critical current density. At the current level of manufacturing technology for a high-temperature superconducting tape, it is not possible to manufacture long high-temperature superconducting tapes that do not completely include deterioration of local...

Switched reluctance motors (SRMs) have many excellent advantages of inherent simple structure, good fault tolerance, high rotating speed, high power and robustness. Magnetic bearing (MB) preserves the characteristics of no friction, no lubrication, free maintenance and long life. Bearingless switched reluctance motor (BSRM) integrates the functions of the SRM and MB. Therefore, the BSRM is...

For the traditional electrical machine, both the stator and rotor core are made of silicon steel sheets, and the main magnetic fluxes are worked in the 2D plane thus the 2D electromagnetic analysis is effective for such kind of electrical machines. However, for particular electrical machines such as claw pole machine (CPM), the accuracy rate of the 2D electromagnetic analysis is not effective...

Due to the wide application of non-linear loads and switching electronic devices, the current in the power grid is often mixed with many harmonic components. The non-sinusoidal currents will have certain effect that unstable voltage and increased heat dissipation on electrical equipment made of superconducting materials, such as superconducting motors, SMES and HTS magnets. In this paper, In...

The Screening Current Induced Field (SCIF) is a crucial measurement to determine the gross contribution of screening currents in a superconducting coil, specifically coils wound with large aspect ratio, single filament high temperature superconductors (HTS) such as Rare Earth Barium Copper Oxide (REBCO). Our numerical model accurately predicted the behavior of the SCIF shape and magnitude...

A number of programs aimed at modeling electrical, magnetic, thermal, and mechanical transients in superconducting magnets and circuits were developed at CERN as part of the STEAM (Simulation of Transient Effects in Accelerator Magnets) project. The framework includes software to accurately model quenches in a superconducting magnet, either self-protected or protected by energy-extraction,...

Abstract: The high-frequency insulated core transformer (ICT) accelerator is expected to replace traditional ICT for its small size and high power density in the field of irradiation below 1MeV. As a key component of the accelerator, the ICT high-voltage power supply is used to feed the accelerator tube. Segmented core structure of the ICT will lead to uneven flux density distribution of...

By using a High-temperature superconducting (HTS) tape, it is possible to realize a coil that can generate much higher magnetic field. However, it is a problem to increase the inductance in an HTS coil since the number of windings increases due to restriction on the current capacity of an HTS tape. For coils with large inductance, large induced voltage and noise are induced between the coil...
