Rolls Royce Rim Driven 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.

Rolls royce rim driven thruster.

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. This technology is based on electric drive where the motor is in the form of a ring round the propeller. The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology. Initial published research based on a scaled cruiseship model estimated that an efficiency improvement in the order of 7 was achievable.

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. One key area of interest is the potential impact of rdps on hydrodynamic efficiency. In response to our customers needs we have launched the thruster support pool tsp.

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. At the same time t. 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.
