Definitions

  • An advantage is that the mechanical complexity of the rim driven thruster is reduced with respect to the known rim driven thrusters. This is at least partially due to the reduced number of (mechanical) parts used in the known rim driven thrusters. It is especially true with regard to known rim driven thrusters in which (solely) mechanical bearings are used.
  • control unit is configured to control the electromagnetic actuator system to provide the electromagnetic bearing by selectively and/or locally generating and/or adjusting radial electromagnetic forces to move the rotor into and/or maintain the rotor in a bearing position.
  • multiple sensors can be used that are positioned at various points along the circumference of the rotor and/or the stator. It is further noted that in some cases the position may be measured by an indirect measurement, for example by measuring a current (or a current amount) through magnetizable coils of the electromagnetic actuator system, or for example by measuring an electromagnetic field strength and/or deviations therein.
  • An advantage of separating the measurement data in two different data streams is that a more detailed control is achieved. By separating the data streams, any deviations or necessary control actions become much easier to detect for the different functions, thus allowing a more precise control of the electromagnetic bearing.
  • the at least one axial bearing comprises two axial bearings.
  • the base layer of the bearing pads is metal, preferably stainless steel
  • the coating is a ceramic or semi-ceramic coating, wherein the coating preferably has a hardness in the range of 600 - 1 ,800 HV, more preferably in the range of 800 - 1 ,400 HV and even more preferably in the range of 800 - 1 ,200 HV and/or wherein the bearing surface is a polymer material, preferably a polymer material having a hardness that is lower than a hardness of the coating.
  • an advantage of this embodiment is that it takes scaling into account. It has been found that, regardless of the scale of the thruster according to the invention, the side surface of the stator, or the part to which the bearing pads are connected, covered by the bearing pads is preferably in the abovementioned range.
  • the housing when viewed along the central axis, may have a shape of a truncated cone.
  • the housing may substantially be shaped as a cylinder or truncated cone.
  • Figure 4 shows an example of rotor and axial bearing of a rim driven thruster according to the invention
  • rim driven thruster 2, 102 may comprise signal filtering unit 158 that is configured to filter measurement data from current sensor 154.
  • signal filtering unit 158 is configured to filter the measurement data in bearing measurement data and rotation measurement data, which are provided to control unit 150 separately. It can also be envisioned that control unit 150 is configured to perform such a filtering step. By separating especially the bearing measurement data from the other measurement data by applying a filtering step in the signal filtering unit 158 a more accurate control by control unit 150 is possible.

Abstract

La présente invention concerne un propulseur entraîné par jante, comprenant : un corps de stator ; un corps de rotor annulaire qui est positionné dans le stator et qui comprend des pales faisant saillie radialement vers l'intérieur ; au moins un palier axial adjacent au rotor, l'au moins un palier axial étant configuré pour transférer et/ou contenir une inclinaison axiale et/ou des forces axiales agissant sur le corps de rotor ; un système d'actionneur électromagnétique qui est configuré pour transmettre sélectivement une force d'entraînement au rotor ; et un palier radial électromagnétique entre le stator et le rotor. L'invention concerne en outre un navire ayant un ou plusieurs de ces propulseurs entraînés par jante et un procédé de propulsion d'un navire.
