AXIAL FLUX ELECTRICAL MACHINES

摘要

An axial flux electrical machine having a rotor rotatable about an axis and the machine comprising at least one metallic pole support unit (10) arranged to have mounted thereon a plurality of cores (34) of magnetiseable material, such that the pole support unit (10) does not substantially electromagnetically link the cores; wherein the pole support unit (10) is provided in at least a region of the axis (14) and/or in a circumferential region of the machine radially displaced from the axis, wherein the material of the or each pole support unit (10) does not surround the cores; and wherein the force exerted by the or each pole support unit (10) on each core is generally in a radial plane of the machine and applied to the core within a length (L), in an axial direction of the machine, of each core (34).
