Definitions

  • the present invention relates to a ring propeller and a thruster comprising a ring propeller which is driven by a permanent magnet motor.
  • an object has been to provide a permanent magnet-driven thruster with greater efficiency than known thrusters. It has been a further object to provide a permanent magnet-driven thruster with a ring propeller which offers better control of when cavitation sets in and the extent of the cavitation.
  • the ring propeller 12 further comprises permanent magnets (not shown in the figures) which are preferably mounted in the ring 15.
  • stator windings (not shown in the figure) are similarly provided, with the result that the ring propeller is driven by a permanent magnet motor. Electric power for the permanent magnet motor may, for example, be supplied via the attachment element 17.
