  • Such a drive is capable of any long nominal torque at standstill to deliver. This makes it possible to be a very effective one Load transfer from the engine to the brake respectively from the brake to the engine. Especially vibrations caused by rocking are also avoided due to discontinuous control can arise.
  • By measuring the Speed becomes a very simple and trouble-free Construction provided. The device is thus particularly suitable for being reliable in the field the harsh working conditions on board a Ship to be used.

  • the control unit (11) is included as a frequency converter Space vector modulation method formed, the Actuator (3) controlled and fed from the three-phase network (12) becomes.
  • the usual three-phase network (12) The ship's electrical system can be used.
  • a sequence of use is such that the control panel (17) are generated from manual tax guidelines and the corresponding signals via the signal transmission (16) are transmitted to the controller (13).
  • the Control (13) also receives via the measured value transmission (14) the actual values for the current speed the drive (3). From this data the Control (13) the setpoints for the frequency converter generated. Basically, it is possible to drive the winch to a freely selectable constant holding torque to regulate. This results from the fact that the drive in is able to do this for any length of time To deliver nominal torque at standstill. This attribute makes the three-phase asynchronous motor with frequency converter and space vector modulation methods in a special way suitable for an automatic mooring operation.
  • An electric three-phase asynchronous motor can be in clear through a mathematical model describe so that the current effective engine torque, which is proportional to the cable, for a given Frequency converter circuit also at standstill from the electrical state variables of the motor can be calculated can.
