Cogging Torque Dynamic Reduction Based on Harmonic Torque Counteract

IEEE Transactions on Magnetics, 2022
This paper presents a method to reduce cogging torque in permanent magnet (PM) machines from dynamic control based on harmonic torque counteract (HTC). We find the possibility of dynamic cancellation of cogging torque and harmonic torque by studying their generation mechanism and period characteristics, and further study the current harmonic injection ...

Cogging Torque Reduction by Elementary-Cogging-Unit Shift for Permanent Magnet Machines

IEEE Transactions on Magnetics, 2017
This paper describes a method to reduce cogging torque in permanent magnet (PM) machines by shifting elementary-cogging unit (ECU). The ECU division principle and the feature of cogging torque produced by ECU are also discussed. The proper shift angles for each ECU are deduced according to both fractional and integral slot number per pole, by which any

Control Strategies for the Identification and Reduction of Cogging Torque in PM Motors

2019 International Conference on Electrical Drives & Power Electronics (EDPE), 2019
In this work two different methods for the identification of the cogging torque in three-phase Permanent Magnet (PM) motors are presented. The cogging torque map carried out from these methods is then used in a Field Oriented Control (FOC) algorithm to mitigate the ripple in speed and torque. The first method uses a high bandwidth position control loop
