Abstract
An electrical machine comprising a rotor, a coil and a stator comprising a lamination stack coupled to a tooth, wherein the electrical machine is at least one of a transversal flux machine is described. The electrical machine may be a transversal flux machine such as a transverse or commutated flux machine. A lamination ring is described comprising a plurality of lamination stacks. A lamination stack may comprise a plurality of trenches configured to retain a plurality of teeth. The tooth may comprise a portion of the switching surface, and a portion of a lamination stack may extend to the surface of the tooth to make up a portion of the switching surface. The electrical machine may be configured with a constant air gap, wherein no more than 15% variability in the distance between the stator switching surface and the rotor switching surface.
