An electric motor having an external rotor, an armature shaft passing therethrough, and an internal stator surrounding the armature. The armature is coupled to the stator by a rolling bearing. The improvement comprises the bearing as a double-rowed radial bearing having a common outer ring within the bore of the stator, first and second races, spaced from one another and adapted to receive first and second rows of rolling elements, and first and second inner races worked directly into the armature shaft.
