The Concept
Prop-eye consists of an synchronous motor with internal rotor. Inductors located in the stator (2) are triggered in way that the rotor (3) with its propeller turns synchronically to the demanded frequency. This is possible due to the especially strong permanent magnets embedded in the outer ring.
The axial water-lubricated bearings (5) are floating bearings out of completely maintenance free plastic located in the flanges (4). This has the advantage that one can abdicate from outer bearings. Thus Prop-eye is almost noiseless, very efficient and robust. Stator and rotor do not touch. Even water plants and water particles can pass through the gap.
Due to most modern high tech materials like carbon fibres and Kevlar texture the propeller and its ring is highly protected against unexpected crushes from flotsam.
The structure of Prop-eye (Click to zoom)
Prop-eye is an in house development of Klingenburg. Long experimental series took place for optimisation of the propeller as it is today with its different demands between docking maneuver and continuous thrust.
The Prop-eye propeller is balanced for equal thrust in both directions of rotation. All components are completely encapsulate and therefore totally waterproof, robust and callous.
Finally Prop-eye is an reliable partner for skippers.
