The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.
Rolls royce rim driven thruster.
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.
One key area of interest is the potential impact of rdps on hydrodynamic efficiency.
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.
At the same time t.

This technology is based on electric drive where the motor is in the form of a ring round the propeller.
The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets.

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.
They will cover the speed range up to 24 knots.
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.
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.
The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.
First to be introduced to the market is the azp pm l drive 120 size rated at 1 800 3 500kw continuous.
