Kongsberg Permanent Magnet tunnel thruster

The Permanent Magnet tunnel thruster is a new addition to the Kongsberg Maritime family of thrusters, building on a completely new approach to thruster design and motor integration. The (TT-PM) has been engineered with reliability and through life costs as the focus. 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 space on board. The TT-PM will meet the strictest requirements for performance, noise and vibration, and will be an excellent choice for operations where low noise and high performance is required. The TT-PM is built around permanent magnet motor technology and a propeller running on roller bearings, supported by a central shaft. The central shaft is supported by stays. These stays recover some of the swirl energy created by the propeller, providing additional thrust. The Kongsberg Maritime thruster has been developed following strict requirements to quality. The thruster contains only one moving part compared to mechanical tunnel thrusters, and thus has fewer components subject to wear and tear. A new mounting system allows more relaxed tolerances and permits installation of the thruster at a convenient stage in the construction of the vessel. The mounting system also allows for easy exchange of a complete thruster. The thruster is approved for EAL (Environmentally Approved Lubricant). * Approximate values provided for information only.
