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
