The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets.
Rolls royce rim drive thruster.
As a result there is a design available to suit virtually any application.
In an azimuth thruster the propeller rotates 360 around the vertical axis so the unit provides propulsion steering and positioning thrust for superior manoeuvrability.
Azimuth thrusters rolls royce is a global leader in the supply of azimuth thrusters.
In an azimuth thruster the propeller rotates 360 around the vertical axis so the unit provides propulsion steering and positioning thrust for superior manoeuvrability.
This technology is based on electric drive where the motor is in the form of a ring round the propeller.
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.

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 az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.
Designs have been developed for propulsion and dynamic positioning in response to market requirements.
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 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.
