Reduction of Cogging Torque in Permanent Magnet Flux-Switching Machines

Journal of Electromagnetic Analysis and Applications, 2009
Permanent magnet flux-switching machine (PMFSM) is a relatively new structure. Available literatures mainly focused on its general design procedure and performance analysis. In this paper, Finite Element Method (FEM) is taken to ana-lyze various design techniques to reduce the cogging torque in a prototype 12/10-pole PMFSM.

Structural Control of Photoconductivity in a Flexible Titanium‐Organic Framework

Advanced Materials, Volume 37, Issue 52, December 29, 2025.
The concept of flexibility is extended to titanium frameworks and use it to gain control over charge transport. MUV‐35 is a flexible doubly interpenetrated framework that can shrink spontaneously its volume by ≈40% to afford a photoconductive, porous state that is thermodynamically favored by non‐covalent interactions. Abstract The soft nature of Metal‐

A High‐Precision Triboelectric Rotational Sensor for Enhanced Low‐Speed Monitoring via Magnetic Modulation in Smart Fitness Systems

SmartSys, Volume 1, Issue 4, December 2025.
ABSTRACT Real‐time detection of low‐speed motion and precise monitoring of low‐intensity exercise are crucial for smart fitness systems. These capabilities enable continuous data acquisition, capture subtle motion variations for personalized guidance, and enhance training effectiveness while reducing the risk of injury. However, conventional rotational

Rotor skew pattern design and optimisation for cogging torque reduction

IET Electrical Systems in Transportation, 2016
This study examines the effects of different rotor skew patterns on the cogging torque, the excitation torque ripple, the average torque, and the axial force in an interior permanent magnet synchronous motor. A genetic algorithm is used to minimise the cogging torque for different skew patterns based on analytical functions. The optimal design obtained
