ABSTRACT:
A multi-phase transverse flux machine includes a primary component having individual bundles of lamination elements which are spaced at a mutual separation distance in a direction defined as the longitudinal direction of the transverse flux machine. Each such bundle of lamination elements has leg members extending in a direction transverse to the longitudinal direction of the machine. The leg members are spaced at a mutual separation distance and are arranged in respective rows. The rows extend in the longitudinal direction. Each such row of leg members is excited by a respective exciting winding excited in such a way that the flux in the transverse direction at the various leg members reaches a maximum in a sequence. A secondary component includes rows of permanent magnet elements extending in the longitudinal direction of the machine. These rows of permanent magnet elements are disposed next to each other in the transverse direction of the machine, and each such row is associated with a row of leg members of the lamination element bundles. The permanent magnet elements are disposed at a distance from the free ends of the corresponding leg members. In each row of permanent magnet elements, the elements are arrayed in a sequence of alternating polarity. The permanent magnet elements of each longitudinal row of permanent magnet elements are displaced in the longitudinal direction, with respect to the permanent magnet element in the nearest neighboring rows of longitudinal row, such that when the exciting windings are excited, the secondary element is caused to move in the longitudinal direction of the machine.
