Abstract
A press cylinder having at least one drivable device and having a generator assigned to the press cylinder for generating electrical energy for actuating the drivable device is disclosed. A generator housing of the generator is permanently connected to the press cylinder and rotates with the press cylinder. A generator rotor belonging to the generator and enclosed by the generator housing rotates relative to the generator housing, and it being possible for the generator rotor to be driven by an electric motor.
Claims17
A press cylinder arrangement having a drivable device and comprising:
- a press cylinder,
- a generator assigned to the press cylinder for generating electrical energy, and
- an electric motor including an electric motor rotor,
- wherein the generator includes a generator housing, which is disposed externally of, permanently connected to, and rotatable with the press cylinder, generator windings assigned to the generator housing, and a generator rotor, which is enclosed by and rotatable relative to the generator windings and the generator housing, and
- wherein the generator rotor is fixed to said electric motor rotor for rotation with said electric motor rotor so as to be drivable by said electric motor relative to the generator windings and the generator housing.
