Abstract

A sensor device includes an exchangeable module shaped as a substantially annular disk and concentrically mounted at or on a shaft of an electric machine. The exchangeable module includes a detection device for detecting a bearing current of the electric machine and an energy converter device configured to convert mechanical energy of the shaft into electrical energy for transmission to the detection device.
