This technology is based on electric drive where the motor is in the form of a ring round the propeller.
Rolls royce rim driven thruster.
Rim drive propellers or rim driven propulsers and thrusters voith rdp.
The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets.
Our thruster support pool provides replacement units enabling the exchange of a complete shipset of azimuth and tunnel thrusters or just a single thruster as part of a planned maintenance solution.
Initial published research based on a scaled cruiseship model estimated that an efficiency improvement in the order of 7 was achievable.
Permanent magnet technology the pm tunnel thruster technology offers numerous advantages over traditional tunnel thrusters including significant reduction i.
They will cover the speed range up to 24 knots.
First to be introduced to the market is the azp pm l drive 120 size rated at 1 800 3 500kw continuous.
In response to our customers needs we have launched the thruster support pool tsp.
The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets.
After over a decade of research and development rolls royce is heading into full production of their permanent magnet tunnel thruster from their facility in ulsteinvik norway.
The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.
The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.
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.
This level of benefit is also reflected in the information published by rolls royce on its rim driven thruster technology.
