Abstract

PM Transverse Flux Machines (PMTFMs) can achieve higher torque densities than conventional PM Longitudinal Flux Machines (PMLFMs). Unfortunately, a general problem of PMTFMs is their high cogging torque in comparison to the average torque. Because of this, a new optimization method for reducing cogging will be introduced in this paper. It uses discrete skewing of a segmented stator. The results are based on FEM investigations and validated by measurements at a prototype.
