Prediction of the electromagnetic torque in synchronous machines through Maxwell stress harmonic filter (HFT) method [PDF]
, 2006 For the calculation of torque in synchronous motors a local method is analysed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air-gap.

Cogging Torque Mitigation using the Unequal Rotor Slot Arcs Method based on Magnetic Permeance Distribution for Flux-Switching Machines [PDF]
Journal of Electromagnetic Engineering and SciencePermanent magnet machines, such as flux-switching permanent magnet (FSPM) machines, are characterized by cogging torque, which must be addressed because it leads to torque fluctuations.

An Axial Magnetic Gear With Improved Torque Density and Reduced Cogging Torque
Iranian Journal of Electrical and Electronic Engineering, 2021 A new axial magnetic gear (AMG) with enhanced torque density and reduced cogging torque is proposed in this paper. In the new structure, the direction and width of permanent magnets in high-speed rotor are changed and permanent magnets are removed from the modulator while the low-speed rotor remains unchanged.

Cogging torque minimization in transverse flux machines
2016 IEEE Energy Conversion Congress and Exposition (ECCE), 2016 This paper presents the design considerations in cogging torque minimization in two types of transverse flux machines. The machines have a double stator-single rotor configuration with flux concentrating ferrite magnets. One of the machines has pole windings across each leg of an E-Core stator. Another machine has quasi-U-shaped stator cores and a ring

Cogging Torque Analysis in Permanent Magnet Machines [PDF]
, 2021 This work analyzes cogging torque in special electrical permanent magnet (PM) machines. Cogging torque is the no load reluctance torque. Cogging torque arises due to the magnetic attraction between the slotted stator and permanent magnet at no load ...
