Abstract

A stator or a rotor for an electrical machine comprises a plurality of circumferentially separated, radially extending teeth, wherein each tooth having a single winding and is provided with an axially and radially extending reluctance barrier to increase the reluctance of each tooth regarding propagation of a magnetic field not interacting with the winding of said tooth.
