Abstract:
1. An electrical machine comprising: an outer stator, a top insulating disk positioned on one end face of the stator having an inner opening with an inner wall extending in an axial direction, an inner rotor comprising a rotor shaft, and a first bearing for the inner rotor, wherein the first bearing is supported on a first bearing block which in its turn is supported axially on an end face of the outer stator and radially by said inner wall of said first insulating disk, wherein the first bearing block comprises retaining fingers which extend in axial direction to reach in a slot in the outer stator, wherein the length of a finger is substantially less than an axial length of a slot, respectively; a second bearing for the inner rotor, a bottom insulating disk positioned on the other end face of the stator; wherein an inner wall of the second insulating disk is provided with a latching hook which effects an axial fixing of a second bearing block, and wherein the outer side of the second bearing block facing away from the bearing is supported radially on an inner wall of the second insulating end disk.
