Rolls-Royce | Permanent Magnet Technology

permanent magnet motor technology PM for short has been introduced in several ranges of rolls-royce marine equipment the PM motor consists of two main parts a stator that carries a number of electrical coil windings and a rotor fitted with a number of very strong permanent magnets a rotating magnetic field is created by the stator which interacts with the fields of the permanent magnets on the rotor this generates a force which drags the rotor round providing mechanical power p.m. opens the way for innovation in marine propulsion the PM motor can form a thin ring around the propeller the stator is the stationary part and the rotor carries the propeller blades a reduction in noise and vibration is the result PM tunnel thrusters were the first rolls-royce products to be introduced to the market and are now joined by azimuth thrusters azpm other types will follow the permanent-magnet azimuth thruster has been through a comprehensive and successful program of testing for function reliability and durability using a fully instrumented test rig the result is an environmentally friendly fuel efficient thruster with reduced noise and vibration levels and hardly no cavitation the space demand is significantly reduced and no inboard cooling system hydraulic pumps or power packs are needed the thruster has reduced maintenance at docking intervals and is equipped for remote condition monitoring in 2015 to a zpm technology demonstrators were manufactured for a long term evaluation program on the research vessel gonner as' owned and operated by NTNU the Norwegian University of Science and Technology they have now been propelling Gunnar as' for more than a year as the vessel carries out its intensive research support schedule running more than 1,500 hours trouble-free now with these estimates we have double power sideway we have much more power than we have earlier we have 100% power all the way and it's been a me like this p.m. technology offers reliability efficiency low lifetime costs low environmental impact and simple installation permanent magnet motors the future dry of technology from rolls-royce

It’s a great technology to get the motor outside the hull, but a terrible design for sailboats. Sailboats primarily “sail” and that means minimizing drag with things like feathering or folding props. Dragging the motor through the water isn’t a good thing here.

It’s neat, literally like every other electric motor though, just putting the blade in the middle instead of a drive shaft. Personally I went with thunderstruck 10kw kit.

Looks expensive as f

Looks cool, I rarely trust first generation designs, but it'll be interesting to see how it pans out.

[u/notquiteworking]

It’s a new application but otherwise the motor technology is nothing new

Moving parts that interact underwater will suffer drastically from fouling, barnacle growth, and debris.

If I ever have enough money to actually get a sailboat, I intend to replace the engine with a DC motor. Ideally I'd like to have a large battery bank and solar array, so I could be independent of land -so long as I have enough food/water.

Electric Yacht sells inboard electrics for boats up to 45 feet.
