An electrical machine including a stator, a rotor and a bearing arrangement having a first bearing and a second bearing on opposite sides of the stator as well as a shielding arrangement comprising a first shielding unit and a second shielding unit. The rotor is rotatably supported around a rotation axis by means of bearings. The shielding units are electrically conductive and comprise a ring part in each case that extends originating from a radial inner end to a radial outer end away from the rotation axis. Preferably each shielding unit has a circumferential part on its radial outer end that extends in a continuous ring-shaped manner around rotation axis and is arranged in overlapping manner with the adjacent axial end of stator winding in axial direction. The circumferential parts are preferably completely closed, whereas the ring parts can comprise through holes.
