The study of rock magnetism has great significance in the environment magnetism and paleomagnetism [1]. Scanning magnetic microscope based on the superconductivity quantum interference device (SQUID) is used for magnetic measurement of rock samples. To obtain the magnetic properties of a sample, such as saturation isothermal remanence (SIRM), the SQUID microscope needs an extra magnetization and demagnetization...
The main objective of the WEST project is to test the actively cooled tungsten plasma facing components under high flux conditions and to provide relevant information to ITER [1]. In this framework, two new power supplies will be installed in Tore Supra in order to feed the new upper and lower divertor coils. These new coils are installed inside the vacuum vessel to modify the magnetic configuration...
Novel stator permanent magnet synchronous machines (SPMSMs) which adopt doubly salient stator and rotor structure and non-overlapping winding are investigated in this paper. Several new SPMSMs topologies are developed, including magnets in the stator poles and on the stator pole surface, respectively. It shows that amongst various SPMSMs, the surface-mounted SPMSM exhibits higher torque density, lower...
This paper presents an analysis of winding configurations in the novel 12-stator pole variable flux reluctance machines (VFRMs), which employ a doubly salient structure with stator located DC field windings. Compared with other doubly salient machines, including switched reluctance machines (SRMs) and doubly-fed doubly salient machines (DFDSMs), the winding connections are not fixed in VFRMs due to...
Planar contactless battery charging system is an emerging technology that can be applied to a wide range of portable consumer electronic products. Beginning with a brief historical background, this paper presents a patent-pending single-layer winding array structure with cylindrical ferrite cores for planar contactless battery charging systems. Complying with the “Qi” standard, this design enables...
