Abstract
An electric machine includes an external rotor rotatable about a rotation axis, and a stator arranged in coaxial relationship to the rotation axis in the external rotor. The stator is comprised of a first stator portion to define a core element, and a second stator portion arranged in the form of a ring in surrounding relationship to the core element and including radially inwardly directed teeth to define a comb-shaped configuration with slots which taper towards the rotation axis for receiving a stator winding. The comb teeth have free ends which are supported on the core element.
