Abstract
An electric motor includes a rotor with a rotor shaft mounted in at least one bearing bush of a friction bearing, a stator which surrounds the rotor, and at least one circular bearing plate which, relative to the rotor shaft, is mounted on the rotor shaft for co-rotation. An inner contour of the bearing plate surrounds a circumference of the rotor shaft by press-fit. The inner contour of the bearing plate is defined by at least two internal dimensions, wherein at least one internal dimension is smaller than the diameter of the rotor shaft. The at least one bearing plate is deformed in an axial direction when the bearing plate is in the pressed-in state on the rotor shaft.
