Abstract

The invention relates to an electrical machine which comprises a rotor with a winding overhang; a laminated stator core; an air gap between the rotor and the stator or the winding overhang and the stator; and a monitoring device for detecting the state of the surfaces limiting the air gap. The monitoring device comprises a conductor applied to the rotor, an energy source connected to the conductor and a detector for detecting the flow of energy in the conductor, the conductor winding around the rotor axis.
