The Norwegian company Brunvoll has been developing just such a device since 2002 and following a successful development program, was chosen to pioneer a research. The five-thruster variation allows all four horizontal thrusters to thrust in any horizontal direction simultaneously while multiple vertical thrusters further allow for pitch and roll functions via asymmetrical thrusting. Hyball ROV OFFSHORE HYBALL shares all of the unique features that have made Hyball so successful but with the added benefit of increased power. ), proper pitch for propeller for efficiency vs. Zhang, Li-wei, Li, Zi-ru, He, Wei, and Zhu, Ling-yu.

So I asked a similar question here before, how to sync vehicle wheels, and I tried applying the answer to this case but it didn't work. I was just thinking about wanting an off the shelf solution for a rim driven drive system, could a stepper motor provide the outer ring of slators and inderting a new set of perminant magnets with a internal prop? if a stepper motor with 12(6,9,12,15 ect would work) coil could be found a standard RC motor controller might work to drive it :) does that make sense?. With 11 thrusters, unrivalled payload and a host of advanced technology features, the ‘Leopard’ can handle more tooling, cameras and survey equipment than any other ROV in its class.

The stator is sealed in the outer rim of the thrusters and the Magnets rotate on a inner rim. The task is derived from the aXatlantic project, aiming at a solar powered, autono-mous and unmanned crossing of the Atlantic. The vessel is equipped with efficient azimuth thrusters and a dynamic positioning system for safe. " The thrusters and reaction wheels orient the spacecraft in three axes which are maintained with great precision. RIM-DRIVEN THRUSTERS Daniel Frank University of Florida Gainesville, Florida, U. DC or induction motors), but there is a general preference for permanent magnet machine types due to the greater power density and efficiency that they offer. If your thruster has high efficiency you ca. Conventional propellers need a shaft line driven by a turbine; a diesel engine or an electric motor. My goals are as follows: * 4 Degrees of Freedom (Forwards/Reverse, Left/Right, Up/Down, and Yaw). manufactures heavy duty commercial marine propulsion and thrusters. Hyball ROV OFFSHORE HYBALL shares all of the unique features that have made Hyball so successful but with the added benefit of increased power. 2) allows only fore/aft/yaw, while the fourth thruster also allows lateral translation.
