Active cogging torque construction by the weld slot design in a positioning servo system
IET Electric Power ApplicationsThe cogging torque is usually considered as an adverse effect of the PM machine servo system. This paper presents a new perspective that the cogging torque can be exploited in many practical situations as long as the speed ripple can be suppressed.

IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.This study proposes a hybrid topology optimisation framework for permanent magnet motors that integrates the Boolean Geometry Projection (BGP) method with a Gaussian‐based ON‐OFF method. The proposed approach automatically generates manufacturable and diverse magnet structures such as U‐, V‐ and double V‐shapes, achieving higher average torque and ...

Comparative Analysis of Electromagnetic Performance of PM and HTS Excited Flux Switching Machines
IET Science, Measurement &Technology, Volume 20, Issue 1, January/December 2026.We introduce and validate an innovative generator topology of a flux‐switching machine (FSM) utilising high‐temperature superconducting (HTS) stator‐side field coils (HTS‐FSM). The results demonstrate that the electromagnetic performance of the HTS‐FSM offers a viable, sustainable and geopolitically secure foundation for the development of next ...

Cogging Torque Reduction Design for CVVT Using Response Surface Methodology
The Transactions of The Korean Institute of Electrical Engineers, 2016 This paper deals with the design process for an outer-rotor-type surface-mounted permanent magnet synchronous motor (SPMSM) used in continuous variable valve timing (CVVT) systems in automobiles with internal combustion engines. When the same size, outer-rotor-type SPMSMs generate larger torque and more stable than inner-rotor-type SPMSMs.
