The permanent magnet tunnel thruster tt pm is our latest tunnel thruster design and has been engineered with reliability and through life costs as the focus.
Rolls royce rim thruster.
Using permanent magnet motor technology increases efficiency and makes the installation more compact only the variable frequency drive unit is housed in the thruster room freeing up.
Permanent magnet technology the pm tunnel thruster technology offers numerous advantages over traditional tunnel thrusters including significant reduction i.
Tunnel thrusters are positioned fore and aft on a wide range of ships and provide sideways thrust for maneuvering and holding position in rough seas.
In response to our customers needs we have launched the thruster support pool tsp.
This will be followed by two smaller frame sizes 085 and 100 and one larger the 150 so that this azimuth thruster series will in due course span a power range from 900kw to 5 000kw.
The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets.
This level of benefit is also reflected in the information published by rolls royce on its rim driven thruster technology.
The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.
Admittedly this technology is not cheap and rolls royce says owners can expect about a 100 markup at the moment on pm azimuth thrusters compared to conventional systems however the advantages.
This technology is based on electric drive where the motor is in the form of a ring round the propeller.
