Superconducting thin rings with finite penetration depth

, 2003
Recently Babaei Brojeny and Clem [Phys. Rev. B 68, 174514 (2003)] considered superconducting thin-film rings in perpendicular magnetic fields in the ideal Meissner state with negligibly small magnetic penetration depth and presented useful analytical ...

Observation of breather-like states in a single Josephson cell

, 2002
We present experimental observation of broken-symmetry states in a superconducting loop with three Josephson junctions. These states are generic for discrete breathers in Josephson ladders.

Design of doubly salient permanent magnet motors with minimum torque ripple [PDF]

, 2009
This paper presents a design approach for doubly salient permanent magnet (DSPM) motors, aiming to minimize the torque ripple. The key is to propose the design criteria that the reluctance of all magnetic paths is the same, and the armature windings can ...

Mutual Inductance Route to Paramagnetic Meissner Effect in 2D Josephson Junction Arrays [PDF]

, 2001
We simulate two-dimensional Josephson junction arrays, including full mutual- inductance effects, as they are cooled below the transition temperature in a magnetic field. We show numerical simulations of the array magnetization as a function of position,

Electromagnetic analysis of a surface-mounted permanent magnet motor [PDF]

Engineering and Technology Journal
This study investigates the finite element analysis (FEA) of a surface-mounted permanent magnet motor (SMPMM) using QuickField software. The model was developed by solving Maxwell’s equations on meshed SMPMM geometries, integrating real B-H curve ...
