  • Patent number: 9874868
    Abstract: A method for calculating an optimized trajectory with a simulation program and an optimization routine includes making available a trajectory and adjusting it to boundary conditions, implementing a loop having the steps of a provision of one first trajectory, a modification of a (further) trajectory and adjustment of the (further) trajectory on the basis of boundary conditions, using as the optimized trajectory a trajectory which has been made available on the basis of an extremal or predetermined parameter, and, after being calculated, making available the optimized trajectory to a control device in order to move a holder for a component part.

  • Patent number: 9346095
    Abstract: A die cushion drive includes a first pump, operated by a first electrical machine and at least one hydraulic cylinder having first and second chambers, with the first chamber in fluid communication with the first pump. A die cushion mechanically connected to the hydraulic cylinder. During a controlled movement of the die cushion, a pressure regulation and a preliminary control are active, with a second pump being coupled to a second electrical machine. During preliminary control, the second electrical machine is operated as a generator, with a first valve being used as an adjustment element of the pressure regulation.

  • Patent number: 8955789
    Abstract: In a method and a device for winding an acentric coil former, the coil former is set into a rotary motion with a winder drive, wherein the rotary motion of the coil former causes a wire attached to the coil former to be wound onto the coil former and unwound from a drum operatively connected to a brake drive, and the winder drive or the brake drive, or both, are controlled based on a rotation position of the coil former. The wire is unwound from the drum with a non-constant speed.

  • Publication number: 20090285517
    Abstract: A drive facility having an electric motor and a bearing arranged outside the motor for coupling a load shaft to a engine shaft of the electric motor is disclosed. The bearing has an outer ring, an inner ring and several rolling elements which are arranged between the outer ring and inner ring. An axial and a radial force are transmitted by the bearing from the load shaft onto the electric motor. The outer ring of the bearing is connected to a stationary component of the electric motor. The inner ring of the bearing is connected to a rotating component of the motor and is connectable to the load shaft. A torque generated by the motor is transmitted from the engine shaft to the inner ring.
