An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder unnecessary. These give ships better maneuverability than a fixed propeller and rudder system. Watching more videos from channel: https://goo.gl/wQd4aC Please like, share and subscribe thank you everyone.
The Rolls-Royce Thruster Support Pool provides replacement units, enabling the exchange of a single or a complete shipset of azimuth and tunnel thrusters as part of a planned maintenance solution, minimising downtime and maximising vessel availability. We understand that our customers require a quick, efficient turnaround when thrusters need to be overhauled Rolls-Royce.

The AZ-PM thruster is the latest in a range of Rolls-Royce propulsion products using its permanent magnet technology. 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. The rotor, fitted within a series of magnets, turns within an outer ring which form the stator. When current is supplied to the motor from the variable frequency power supply the electromagnets are excited in a particular sequence and the resulting magnetic fields interact with the field from the rotor magnets creating a torque that turns the rotor and its propeller blades. At the centre of the thruster the propeller blades are joined to a hub, which h...
A clean underwater hull without dragging a feathered propeller through the water was, until recently, only seen on racing yachts. Our novel development of direct drive pods, offers this opportunity now also to performance cruising yachts. This is a new advancement which will certainly be used on many future yachts and which offers improved performance, also on existing yachts originally designed for cruising.
In the traditional azimuth propulsion system the motor is inside the ship's hull and the propeller is driven through shafts and gearboxes. In the Azipod system the electric motor is inside the pod, and the propeller is connected directly to the motor shaft. By not using a traditional propeller shaft, the propeller can be farther below the stern of the ship in a clear flow of water providing greater hydrodynamic and mechanical efficiency. Electric power for the Azipod motor is conducted through slip rings that allow the Azipod to rotate through 360 degrees. Because fixed pitch propellers are used in Azipods, power for an Azipod system is always fed through a variable-frequency drive or cycloconverter that allows speed and direction control of the propulsion motors.
