Abstract:
The invention relates to an external stator of a rotating-field machine with internal rotor, which external stator is designed as an internal stator or external stator and which external stator has a number of N stator teeth which together form a number of N/2 tooth groups, and each stator tooth has in each case one pole core and one pole shoe integrally formed thereon, wherein the pole cores are manufactured from a first material, and that in each case one tooth group is formed by two directly adjacently arranged stator teeth which, together with a magnetic return means, are constituent parts of a magnetic circuit, characterized in that, between two adjacent stator teeth of two adjacent tooth groups, there is arranged in each case at least one intermediate element which extends in particular in an axial direction of the stator and which is manufactured from a second material, and in that differs from the first material of the pole cores.
