I'm a mechanic helping research how to convert an existing bow thruster, from hydraulic to electric. The hydraulic system is shot and needs to be replaced. Captain was piloting a newer vessel he helped someone purchase and noticed how nicely it's 24 volt bow thruster worked. So now he want's to have that installed, but I can't find anything to actually make this work
I've seen some complete systems that are capable of running off of 24 volts, but their tunnels are half the size. The captain thinks his system is 20 horsepower, which means I'm looking for a unicorn motor that Google doesn't have indexed!
Maybe something that chews up 700 amps at the push of a button, only running at 20% duty-cycle? Only see about 3 or 4 threads on this site alone with anything bow-thruster-like
Is there any such motor? I've been looking and starting to get the feeling maybe I don't know how to find this one
I see systems like this: https://www.vetus.com/en/manoeuvrin...usters/vetus-boegschroef-160-kgf-24-volt.html
Almost but not sure how close. I should go crawl around the bilges and see what were dealing with first, probly
Boat was just recently hauled out for bottom paint and nobody thought to measure the diameter of the tunnel or even look at the blade pitch. No idea what gear ratio on the drive, only that it's a 90 degree box inside the tunnel and maybe there's two props? Actually, the captain should know at least that one. But if they counter-rotate or not? Maybe I'm over-thinking this
I could look at the existing hydraulic motor and see if I can find it's rated RPM and power
Captain just wants to quickie-weld a shaft adapter onto something pulled from a wrecking yard and 'call it good'. Controls are to be simple push-buttons up by the wheel activating solenoid actuators. Full power or bust, I guess. Captain is a retired tugboat operator, so I guess he prefers to power into/away from everything...
Can I get away with having a 500 volt industrial inverter wired up to momentary on, with reversing solenoids after that inverter, all powering a forklift motor? Entire works powered off the existing 24 volt battery banks, of course
I could email Vetus, or somebody, and ask for just the motor & controller on their system. Not sure how well that will work out
Likely we're either just going to install new hydraulics or just keep on going without a bow thruster. But after putting in LED lighting and seeing what's happening out there, captain really wants to have something to brag about that's portray-ably cutting edge. He doesn't like complicated systems, so computerized variable-frequency drives and Star-Trek warp shifters are all totally no-go!
