    摘要： The invention relates to an active part of an electrical machine, comprising: teeth (1), each having a tooth base (2) and a dedendum (3); open or closed grooves (4) between the teeth (1); and windings (8) introduced into the grooves (4), which windings each enclose at least one of the teeth (1). The active part has an active part thickness (5), starting from the outer surface of the respective tooth bases (2) and in extension of the teeth (1), that is greater than the dedendum (3). The active part, starting from the respective tooth base (2) down to a critical depth (9), which is not more than equal the dedendum (3), has a first material with a first magnetic permeability and starting from the critical depth (9) a second material with a second magnetic permeability, the first magnetic permeability being greater than the second magnetic permeability. The invention further relates to said electrical machine, to a radial magnetic bearing having said active part and to a method for producing said radial magnetic bearing. In order to make an active part available which has comparatively good magnetic properties and is cost-effective to produce, the critical depth (9) is between 20% and 100% of the dedendum (3).

    摘要： The invention relates to a radial magnetic bearing for magnetic bearing of a rotor (5), wherein the radial magnetic bearing (1 ',1 ' ', 1 ' ' ' ) has a stator (2), wherein the stator (2) has a magnetically conductive stator element (4), arranged circulating around the rotor (5), wherein the stator element (4) has recesses (10) running in the axial direction (X) of the stator element (4) in which electrical lines (8a, 9a) from coils (8, 9) are arranged, wherein magnetic fields can be generated by the coils (8, 9) which hold the rotor (5) suspended in an air gap (7) arranged between the rotor (5) and stator (2), wherein a softer progression of the components of magnetic flow density in the radial direction is achieved by design measures on the transitions from one magnetic pole to the next magnetic pole, which results in a reduction of the eddy currents induced in the rotor (5).
