A rotor for a reluctance machine includes conductor layers and insulation layers arranged in alternation in the axial direction. The conductor layers have magnetic-flux-conducting conductor regions and the insulation layers are electrically insulating. To improve weight and efficiency of a reluctance machine, the rotor is produced at least partially by additive manufacturing.

An active part of an electrical machine includes teeth, each having a tooth base, a tooth height, open or closed grooves between the teeth, and windings introduced into the grooves. Each winding encloses at least one of the teeth. The active part has a thickness, starting from the outer surface of the respective tooth bases and extending along the teeth, that is greater than the tooth height. The active part, starting from the respective tooth base up to a limit depth, which is not more than equal the tooth height, has a first material with a first magnetic permeability and starting from the limit depth a second material with a second magnetic permeability. The first magnetic permeability is greater than the second magnetic permeability. The limit depth is essentially half as great as the tooth height.

The aim of the invention is to better compensate for specifiable forces on a magnetic mounting. This is achieved by a magnetic mounting device with a first magnet device (), which is designed in an annular manner and which has a central axis, for retaining a shaft on the central axis in a rotatable manner by means of magnetic forces. The magnetic mounting device additionally has a second magnet device (), which is independent of the first magnet device (), for compensating for a specifiable force acting on the shaft. In this manner, the magnetic mounting device can compensate for the gravitational force or forces based on imbalances.

A ring motor () as a direct drive, particularly for vertical mills or rod mills, has a stator () and a rotor () configured as a rotating milling body (), wherein the stator () has at least two different excitation systems, and the milling body () has only a toothed structure, which electromagnetically interacts with the excitation systems of the stator () and thus brings about a rotation of the milling body ().
