As a result there is a design available to suit virtually any application.
Rolls royce rim drive thruster.
This technology is based on electric drive where the motor is in the form of a ring round the propeller.
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.
Azimuth thrusters rolls royce is a global leader in the supply of azimuth thrusters.
The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets.
Rolls royce unveils permanent magnet azimuth thruster at norshipping june 4 2015 by rob almeida two pm azimuth thrusters conservatively rated at 500kw have been fitted to the research vessel.
The twin engines developed a net thrust of 223 kn 50 000 lbf giving a power output of roughly 102 000 bhp 76 mw at the.
This technology is based on electric drive where the motor is in the form of a ring round the propeller.
Designs have been developed for propulsion and dynamic positioning in response to market requirements.
This is significant as it not only reduces the total energy consumed from ship propulsion but also reduces the total installed generation power on the ship associated infrastructure and fuel usage saving cost and space.
The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets.
The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.
In an azimuth thruster the propeller rotates 360 around the vertical axis so the unit provides propulsion steering and positioning thrust for superior manoeuvrability.
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.
