FIELD: rotating electric machines.
SUBSTANCE: invention relates to a device (4) for registering a high-frequency event signal in a rotating electric machine (2). Essence: in a rotating electric machine (2) there are at least two sensors (28) for registering a low-frequency signal. The sensors (28) include an antenna for outputting a high frequency event signal from the high frequency electromagnetic field of the rotating electrical machine (2). The sensors (28) are connected via a common, in particular reactive, coupling element (36) to a common HF evaluation device (38). The reactive element (36) of the connection contains a transformer. Each of the at least two sensors (28) is respectively assigned a primary winding (40, 42, 44), and the HF evaluation device (38) is assigned a secondary winding.
EFFECT: possibility of simple implementation of the device.
