The Effects of Cogging Torque Reduction in Axial Flux Machines. [PDF]
Micromachines (Basel), 2021 An axial flux permanent magnet single-rotor generator has good potential in various applications that require high efficiency, prolonged service life, as well as low mass and dimensions. However, the effect of cogging torque diminishes generator efficiency and flexibility of functionality.

A Reduction Method of Cogging Torque for Magnetic Gears [PDF]
Iranian Journal of Electrical and Electronic Engineering, 2023 Nowadays, magnetic gears (MGs) have become an alternative choice for mechanical gears because of their low maintenance, improved durability, indirect contact between inner and outer rotors, no lubrication, and high efficiency.

Methods for Reducing Cogging Force in Permanent Magnet Machines: A Review
Energies, 2022 Permanent magnet (PM) machines inevitably suffer from cogging force, which does not contribute to the average output torque (force) but contributes as a type of torque (force) ripple. This paper provides an overview of the cogging force reduction methods

Cogging Torque Reduction in Permanent Magnet Machines [PDF]
IEEE Transactions on Industry Applications, 2006 This paper examines two methods - magnet shifting and optimizing the magnet pole arc - for reducing cogging torque in permanent magnet machines. The methods were applied to existing machine designs and their performance was calculated using finite-element analysis (FEA).
