Design and loss analysis of a new self-decelerating PM in-wheel motor [PDF]
, 2014 This paper proposed a new self-decelerating PM in-wheel motor (SDPMIWM) which replaces the stationary ring of the conventional magnetic-geared motor with the stator teeth and is magnetized in Halbach Array.

Magnetic Resonance in Medicine, Volume 95, Issue 1, Page 637-646, January 2026.Abstract Purpose One of the intrinsic limitations of low‐field MRI is low signal‐to‐noise ratio, which can be further reduced by electromagnetic interference (EMI) due to the lack of a Faraday shielded room. To address this issue, we propose a novel radiofrequency (RF) coil design that is inherently less sensitive to EMI while maintaining high receive ...

IET Electric Power Applications, 2021 The permeability of the iron is usually assumed to be infinite by the linear subdomain technique, leading to the neglect of magnet saturation. This study presents an analytical model of a segmented Halbach array permanent magnet machine by considering ...

Levitation of non-magnetizable droplet inside ferrofluid
, 2018 The central theme of this work is that a stable levitation of a denser non-magnetizable liquid droplet, against gravity, inside a relatively lighter ferrofluid -- a system barely considered in ferrohydrodynamics -- is possible, and exhibits unique ...

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.A subdomain analytical model for multi‐harmonic air‐gap subdomains is proposed to predict motor magnetic fields containing complex harmonic components. Theoretical analysis demonstrates that this model effectively reduces the matrix dimension during analytical computation, resulting in lower computational time costs for the same harmonic order while ...

Design of a Magnetic Field Mapping Rover System for a Neutron Lifetime Experiment [PDF]
, 2015 The beta decay lifetime of the free neutron is an important input to the Standard Model of particle physics, but values measured using different methods have exhibited substantial disagreement.

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.This paper investigates the impact of sleeve segmentation on eddy‐current loss in permanent‐magnet (PM) machines with fractional‐slot concentrated‐windings (FSCW) under different stator MMF harmonics. The concept of equivalent sleeve segmentation is introduced.

A Halbach array magnetic gear for auxiliary drives
Vestnik IGEUA diesel locomotive must drive a significant number of units with different rated rotation speeds from a single diesel engine with minimal energy consumption. The mechanical and hydraulic drives currently in use demand high maintenance and specific oil quality, while electric drives are bulky and have lower efficiency.

Design and Development of a Magnetic Lead Screw With a Quasi‐Halbach Array
IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.This paper reports on a study of a novel MLS with a quasi‐Halbach array and a rotor made of a SMC. The proposed topology has an array formed from a helix of discretized pieces of PMs axially and radially magnetized in its slider. Using FEA and static magnetic simulations, prototypes were assessed.
