Cogging Torque Reduction in Permanent Magnet Machines [PDF]

open access: yesIEEE 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).

Reduction of Cogging Torque in Surface Mounted Permanent Magnet Brushless DC Motor by Adapting Rotor Magnetic Displacement

open access: yesEnergies, 2021
Cogging torque is a critical dilemma in Permanent Magnet Brushless DC (PMBLDC) motors. In medium-low power PMBLDC motors, redundant vibrations and forbidding noises arise as a result of the harmonic magnetic forces created by cogging torque.

Reduction of Cogging Torque and EMF Harmonics in Modulated Pole Machines [PDF]

open access: yesIEEE Transactions on Energy Conversion, 2014
This paper discusses a method for reducing cogging torque and harmonic content of back-electromotive force (EMF) waveforms in modulated pole machines (MPMs). Tooth pitching is applied to a separate phase MPM in order to reduce the most prominent harmonics present in a three-phase MPM's cogging torque.

Cogging Torque Reduction Based on a New Pre-Slot Technique for a Small Wind Generator

open access: yesEnergies, 2018
Cogging torque is a pulsating, parasitic, and undesired torque ripple intrinsic of the design of a permanent magnet synchronous generator (PMSG), which should be minimized due to its adverse effects: vibration and noise. In addition, as aerodynamic power
