Abstract
An internal stator of a rotary field machine has a number of N stator teeth. Two stator teeth each form a number of N/2 tooth groups, wherein one tooth group each is formed by two directly adjacently arranged stator teeth has a pole core and a pole shoe formed thereon, and thus, the inner stator comprises semi-closed grooves. The pole cores are made of a first material, for example, silicon iron. In addition thereto, an intermediate element extending in the axial direction of the stator is arranged between each of two stator teeth of two adjacent tooth groups, which is made of a different material. The second material of the intermediate element is different from the first material of the stator teeth.
