دانلود Cogging Torque Minimization of SMC PM Transverse Flux Machines Using Shifted and Unequal-Width Stator Teeth

Abstract

This paper proposes a method to minimize the cogging torque of a permanent-magnet transverse flux machine (PMTFM) with soft-magnetic-composite cores, using the shifted stator disks and unequal stator teeth pairing. Fourier analysis is performed to find the major cogging torque component so as to reduce it by shifting the stator disks. The unequal stator teeth pairing technique that is traditionally used in the radial and axial flux machines is employed to reduce the cogging torque of PMTFMs in this paper. Three different configurations are studied. The cogging torque and the electromagnetic torque are calculated by the three-dimensional finite-element method and verified by the experiment results.
