A new design approach for reduction of force ripple in permanent magnet flux‐switching linear motor
IET Electric Power Applications, 2023 To reduce the force ripple of the permanent magnet flux‐switching linear motor (PMFSLM), a new design approach is suggested by the authors. The detent force is redefined as the composite force of the thrust of the single action of permanent magnet and ...

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

Application of the DC-ripple reinjection concept to forced-commutated conversion [PDF]
2005 International Power Engineering Conference, 2005 A dc-ripple reinjection concept, described in the literature with reference to the line-commutated current source converter, is applied in this paper to the self-commutated current source converter. This is achieved by means of a reinjection converter fed, via a single-phase transformer, from the triple frequency ripple signal.

Analysis of Electromagnetic Force Ripple in a Bearingless Synchronous Reluctance Motor [PDF]
IEEE Transactions on Magnetics, 2021 A bearingless machine should be designed to maximize the average and to minimize the ripple in the electromagnetic torque and levitating force. In a bearingless synchronous reluctance machine (BSynRM), the complex rotor design and the levitation winding create a rich spatial and temporal spectrum of the magnetic flux density in the airgap, which ...
