Rim Driven Tunnel Thruster
Compact electric rim driven tunnel thruster (RDT) combining propeller and permanent magnet motor in one unit, with no external motor, shafts or couplings. Six sizes from 800 to 2,100 mm propeller diameter, 200 to 1,600 kW.
Description
The Brunvoll Rim Driven Tunnel Thruster (RDT) integrates the thruster, propeller and a permanent magnet motor in one compact electric unit. With no mechanical transmission, it eliminates the need for an external motor, shafts or couplings, saving weight and space and simplifying installation.
Key features
- Thruster, propeller and permanent magnet motor in one unit
- No mechanical transmission losses
- Optimized propeller design for higher efficiency and lower noise and vibration
- Shaftless design with water-lubricated bearings, or central shaft with seals for larger units (e.g. RDT 2100)
- Available as hard-mounted or resiliently mounted units
- Compact design increases arrangement flexibility
