  • Leading sheave mine winding engine with improved cooling air conduction
    Patent number: 7451963
    Abstract: 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).
