Abstract

The invention relates to an easily mountable and highly dynamic radial bearing. According to the invention, a magnetic radial bearing for the rotatable mounting of a rotor (3) is provided, having a stator (2) that comprises several coil assemblies (6). The coil assemblies (6) are arranged around an axis (1) of the radial bearing in a circumferential direction. Each of the coil assemblies (6) has a laminated core (7) having single sheets. Each of the coil assemblies (6) further has an axial field coil (11) that is wound around the corresponding laminated core (7). The single sheets are stacked in the tangential direction in every laminated core (7).
