The invention relates to a Koepe winder or drum winder comprising an electric motor (5) for driving winding ropes (11). The rotor (6) of said motor is connected to the cylinder jacket (4) of the Koepe winder (2) and the stator frame (7) is fixed on a support structure that has a hollow shaft (3). The winder is characterised by an improved ventilation system. The motor (5) is located inside the cylinder jacket (4) in a cavity (12) between the plates (13) of the Koepe winder (2), said cavity being supplied with cooling air to ventilate the motor (5) from the exterior The hollow shaft (3) is formed by two half-shafts (18, 19), which together with at least one support disc (8) and the stator frame (7) form the support structure (10).
Leading sheave winder or a drum winder comprising an electric motor (5) for driving winding ropes (11), wherein a rotor (6) of said motor is connected to a cylinder jacket (4) of the leading sheave winder (2) or drum and its stator frame (7) is secured on a support structure that has a hollow shaft (3), the motor (5) being located within the cylinder jacket (4) and between plates (13) of the leading sheave winder (2) or drum in a cavity (12), where said cavity can be supplied with cooling air to ventilate the motor (5) from an exterior, characterized in that the hollow shaft (3) is formed by at least two half shafts (18, 19), which form a support structure (10) with at least one support disc and the stator frame (7).
