Abstract: A rotor device for a flat brushless electric motor for an automobile roof system has a rotor housing having a first cylinder and a second cylinder. The cylinder elements are configured to be hollow-cylindrical, have different internal and external diameters such that a stator device is disposable between the cylinder elements, and are concentrically aligned with one another. At least one magnetic module is disposed on each cylinder element. A stator device for a stator housing element has a base and a wall element mutually disposed so that the stator housing element is configured in the manner of a pot; and an axle element for externally disposing a rolling bearing for a rotor device. The axle element is disposed in the center of the stator housing element such that the axle element and the wall element, viewed in cross section, extend away from the base element in the same direction.
