The invention relates to a device (5; 105;...; 905) for braking a rotating element (2) of an assembly (1), in particular for braking a rotating shaft of a rail vehicle, comprising a rotating eddy current brake (6; 106;...; 906; 6a; 6b; 6c), which has a rotor (8; 108;...; 908) that can be connected to the rotating element (2) in a rotationally fixed manner and a stator (9; 109;...; 909) that can be supported on the assembly, wherein the stator is provided with at least one excitation coil (11; 111; 211 to 218; 311 to 318; 411, 412; 511 to 518; 611, 612, 613, 614; 711 to 718; 811 to 818; 911 to 918) fed by an electrical energy source (20; 120;...; 920). In order to diagnose the state of the rotating eddy current brake, means (7; 107;...; 907) for the eddy current testing of the rotating eddy current brake are provided, said means having at least one testing coil and an electrical signal source (125; 225;...; 925) operatively connected to the at least one testing coil, wherein the electrical signal source applies a testing signal (U.P; U.P.1;...; U.P.9) to the testing coil during a diagnosis, and said means having at least one measurement coil and a signal receiver (127; 227;...; 927) operatively connected to the at least one measurement coil, wherein the signal receiver taps a measurement signal (U.M; U.M.1;...; U.M.9) suitable for diagnosing the eddy current brake during the diagnosis of the at least one measurement coil. The at least one excitation coil forms the at least one testing coil. Furthermore, the at least one excitation coil and/or a further excitation coil of the eddy current brake forms the at least one measurement coil.
