Ep138 Which Radiator setup works better for electric motor liquid cooling: tests and results
Hello! I have the same engine and I am analyzing how to install it, directly or with a pulley, I watched your videos and I like the latest version better, but why the brake?
@@Sunshine.sailing.project good question! a couple reasons 1) when the electric brake in the vec500 is on, it beeps. continuously! never stops. i can’t figure why they would want it this way and i could not figure out how to turn the beeping off. 2) the direct drive setup uses a jar coupler between the motor and the prop shaft. at very low rpm its very grinding like sound and it sounds like a car crusher grinding its way through some steel. very loud and it starts at about 2 knots of boat speed. so i put the brake in place to stop the free spinning. as for regen it needs 6 knots boat speed to really generate something significant so when its 6knots the jar coupler is not bothersome at all. but at 1 knots 😱 thx for the comments and hope your installation going well!
Wow! Thank you for clarifying so many doubts, I’m also looking forward to having a regeneration, my controller is the EZkontrol and I still haven’t been able to install it on the boat, but it will be ready very soon! Thank you for clarifying so many doubts! Greetings!!
😅😅
@@FortniteChapter3Map thats a super old version! 👍
I'm not an electrical engineer but I know enough about motors to know that, at ~600 watts, that 10 kW motor is doing such little work that, had you bought the air cooled version, I bet the fins wouldn't even get warm. 600 watts @ 48v is only 12.5 amps - we're talking small electric scooter power here. Your pump may even be warming up the water more than the motor. Put 200 amps into this thing for 40 minutes and post a video about it. I run my Segway G30 hub motor for longer than that, peaking around 850 watts, and it doesn't even get warm. And this is a hub motor - inherently difficult to cool without ruining aerodynamics with fins.
@@MikeZ8709 ya that motor is running cool. at 2000 watts the motor slowly increases i run out of batteries before its over 50 deg celsius. my issue is the controller. thats what heats up.
Just spend 300 bucks on a pack of LFP batteries
this is an older video. at the time Lifopo4 was considerably more. appreciate the comment going lithium made a very large positive impact
Hi The Neds - Great to see that you are still going strong in your boating adventures:) Just wanted to let you know that your channel and advise set me on the track of building my own electric motor setup for the 36' sailboat I am building. If I remember it correctly (a while ago now) you expressed an interest in following the build if I ever posted it on UA-cam. I have now posted the first episode showing the motor housing design and should have it welded this coming week. Feel free to check it out. Thank you for all the advise so far and may have some more questions as I am progressing and hope you do not mind:) Thank You / Modular Hippo.
thx for the heads up! best of luck to you with your project. i’ll follow along
Just a few changes/upgrades since this 3 year old vid. A comparison update might be good, incl what you might do differently today, if not already inve$ted in what you have. So much has changed/advanced in the industry.
appreciate the advice will add that to my list of content ideas
Hi Ned's, I am 2.5 years into a Curtis electric inboard on my Redwing 30, located in Bronte. I'd love to take you for a sail and pick your brain if you haven't already headed to the coast!
hi Brynn @brynnnheiley377 be glad to help you out with any questions and love to see your boat sure. i ran into a few challenges I am still in hamilton reach out to me at info@sailons.com
What are you using for your shaft bearing?
a couple of shaft locking collars and flush mount bearing. similar to pillow block bearing but side mounts.
nice
Thanks
Another idea that I might have to copy from you 😂
A pro did that one, Mike from @launchmarineconcepts took a couple visits, one to measure and one to install. Had to be above 12 degrees to install. It's really warmed up the cockpit
Lookin' good!
thx @bradstevens7902 it took a while to get the templates and cuts straight but I'm warming up to it...
Nice dinghy!!!
hey @bradstevens7902 it's gone and has been replaced by a leaky zodiac 9 footer..... ;0

That’s what satisfaction looks like. 👍 Nice work.
Thanks 👍
Hi, I would like to know the caracteristics of your propeller (Size). I have installed a similar golden motor in my boat, and would like to change propeller. thanks
my old prop was the original prop on the atomic 4 gas engine, a Michigan 2 size 16RH14 i changed it this year to a Michigan 3 size 16RH12 to gain more torque while docking. my old 2 blade did not slow the boat down in reverse very well. big difference with the 3 blade. the 2 blade is better under sail as it tucks in nicely behind the keel offering low drag. the 3 blade starts spinning at just over a knot boat speed so increased drag. need to install a brake.
Hi,
hi!
Maybe This dinghy solution could work for you also? It’s 30 for sailboat ua-cam.com/video/JLuRw-Dtk68/v-deo.htmlsi=mrVKlW6mBbScO-Qw
never saw dinghy rings i will have to mull that over thx for the tip
Terrible music why bother
Thanks for that. 48/1200 240v awaiting delivery. No dongle yet as now I know, thanks to you, that I need one. Belfast out.
it worked well for me. i am still using it at a tower site to power the equipment when the power is out from the grid. been working for years now.
looking good already 👌
thx!
Hi, from Quebec... it would be nice if you shared some boat spec, displacement, props spec, etc... I'm going electric too :) thanks !!!
hello from hamilton i will be passing through quebec likely next year, remote chance this year. my boat specs are in the comments a link to sailboat data. its a hughes 35/1500 1975 about 12,000 lbs displacement. was running a 2 blade michigan sailor 16rh14 but this year testing a 3 blade michigan 16rh12. i will post some info once i have some comparison data. this 10kw dc motor replaced my old atomic 4 gas.
@@TheNeds I'm in Matane along the Fleuve Saint-Laurent... Building a 40feet Cat, I will have 2x ME1616 10KW probably with 2 props : 18x14... no idea of what's going to get out of that :)
Where did you get the radiator from
ordered radiators off of amazon
Have you been happy with this Raymarine package after a few years? I assume the masthead winded was no longer needed. Thanks for the helpful video. I’m looking at the same package right now!
Hi I am looking to put one EZ-IB15, In my 28Ft
that’s interesting it wasn’t available when I originally did my electric conversion almost 4 years ago now. it looks like they are using the same motor and vec500 controller but housed it tight together and still offered the liquid cooling as an option. the smart phone app is new and a neat feature but i am still looking for ways to get that info onto the nmea2k network. good luck with your project!
Can i use Victron Energy Converter 48V-12V 9A with 12v to 230v. pure sine inverter?My idea is Make 48v. li-ion battery and put it through Victron,who are connected with 12v. to 230v.inverter.
Hey, where did you get the software from?
download off golden motors site US under motor controllers i think its called Controller Software and its .rar compressed
Hi, love your videos. I have a question: have you limited the max rpm? All other vendors of boat electrival motors have a max rpm of about 2200rpm… the 10kw motor is by default much higher rpm?
hi, yes by default the rpm was 5000 in the VEC-500 controller. it was a bit high when i had the 1.92:1 gear ratio but when i changed to direct drive i lowered it to 2400 max rpm. at this setting i can still create cavitation on the prop so i try to manage with the throttle (easing in and out). thx for the comments appreciated!
How did you attach the motor to that board?
Can this motor be mounted flat (shaft down) ? I dont see any mounting attachment holes...
the motor has 6 hex bolts to attach it on the opposite of the shaft end. i don’t know for certain the implications of mounting with the shaft up or down facing but i would post on the golden motor user forum. i never looked into it. i know from history that electric motors were the vertical orientation motor choice for many applications. good luck !
That is by far too much thermal paste. It shojld be a very thin layer
Thanks for sharing, very informative and inspiring. I have thrown out my diesel now and looking at GM and thinking that maybe 5kw with a gear 3-1 is enough for my 30fot 3.5ton sailboat. You seem to seldom go over 2kw. Im only a weekend sailor. Would it be enough with a 5kw motor for your boat if you had a 3-1 gear?
thx for the comment. i am not certain there is a right answer as your prop and hull shape have a lot to do with it. the 5kw is probably plenty for your boat as it would be fine for mine (hughes 35). the gear ratio is really dependent in your prop. i had 2:1 on mine but i found it using too much energy. after running 1:1 for me 1.4:1 is probably the right ratio so i just changed my prop and dropped the pitch 2. i will test this season. so i would guess that the power is good but i couldn’t comment on the gear ratio. best common sense and testing doesn’t hurt anything. good luck!
@@TheNeds thanks for reply. I was reading up on the data for the 5 and 10kW motors. The motors are most efficient at around 4k rpm so I suppose both motors are made to run at higher rpm? That was my reasoning about a 3-1 reduction to keep the motor at its most efficient rpm. I also noticed that the 10kW is more efficient at 96v. And if you look at torque between both motors at 48v and around 2500W it’s actually more torque on the 5kw and that is because it’s more efficient at 48v and lower W than the 10kW motor, that is how I interpret the data.
If you need to draw more current, just add a second set of series connected batteries, wired parallel to the first set. Repeat as required until you get to your desired current. You could also increase your voltage by adding more natteries on series if you want higher rpm. Current is your acceleration, voltage is your shaft speed. Electric motors woll tolerate quite a bit of overvoltage, and yiur controller is only going to apply voltage based on your throttle position, so for the cost of two batteries, you could give yourself an "ahead emergency" capability that would bump max voltage from 48v to 60v.
@@TheNeds Keep in mind that a voltage increase is also a capacity increase. Assuming you don't ride WFO on the throttle all the time.
Why don you use the water sea to cold the circuit?
Every video of yours is gold to me.
Great video! The people from Golden Motor recommend the EZ-B72800 controller to me, but I guess this is not programmable. When you are sailing, how do you change the gear? Do you know if using the throttle button? Appreciated!
im not quite following your question. im using the VEC-500 controller and it does have the ability to be programmed. i am not familiar with the one you mentioned. in the programming i can set quite a few things but there are no gears. l have a potentiometer style throttle which uses -5 to +5 volts DC to control forward speed and reverse speed.
In this video, you solved my coupling problem! Thanks a lot!!
nice!
Amazing video! I'm from Barcelona and I'm on the process to convert my Furia33 to electric with a 10KW Golden Motor engine. Until now I consider to put a 2:1 reduction with gears but now I see that you've connected directly. My boat has 4tons and the RPM in the propeller right now is 1600 RPM max. Do you recommend to connect the engine directly or with a reduction? Thanks a lot!
i think that with the direct drive im a touch heavier on the torque than ideal prop cavitation is easily reached too quickly with direct drive so i’ve lowered the max rpm setting to 2500rpm but i can still hear the prop screaming. the 10kw is very torque heavy as compared to the 5kw, about 30% more. for me 2:1 was too much and 1:1 to little i think its got to be in the middle of those ratios to reach the highest efficiency of the motor quicker. i found 2:1 just not enough. at 600 watts its up there about 80+ efficient but any less (trolling speeds) is not so i try to bring it to 750 watts to 1700 watts is my range. anywhere less is creating more heat than necessary and any more and thing really start becoming too inefficient and creating cavitation. sorry not a straight forward answer more like it depends but keeping the motor rpm in an efficient space means it will run cooler. also the lower the rpm the longer your batteries last so there is an argument to have a lower gear ratio when considering energy consumption. i am not in a hurry and 100 amps lifepo4 batteries get me about 20 nautical mile range at 3 to 3.5 knots so i’m happy with that. im a sailor not a power boater. i suppose lifestyle matters too in the thinking. i sail almost in and out of dock and i’m not in a hurry to get there.
@@TheNedsmaybe a larger prop would get you to the sweet spot for your motor? Than you can put more torque into the water at lower rpm. Also recuperation should work better/at lower speeds. Downside of course is, it's more water resistance when sailing.
this year i installed a Michigan sailor 3 to replace the michigan sailor 2 that was originally on the boat. i kept the same size (16) but lowered the pitch from 14 to 12. my boat speed is fairly close to the old prop but i have more torque starting and stopping. Also under sail i used to need at least 5 knot to spin the prop but now need just over 2 knots. i had to install a shaft brake to control the free spinning regen as it spins at much lower speeds now. you are right about more drag it feels the same as towing a bucket behind me…. more testing to compare notes but the added torque is getting me in and out of the dock easier.
@@TheNeds Hello! Finally I've installed the golden motor BDLC 10kw in my 33 feet boat. How can I share with you some videos?
@martinconstante if you are on youtube send me your URL
If You are still doing the direct drive setup, it is possible the propeller has a bit too much pitch? Reducing pitch would reduce the load a bit, maybe running cooler also?
What are you using in front of the load plate to isolate radial and axial loads?
as the boat is out of water i took the locking shaft collars off to verify alignment as i pulled the shaft to make sure its straight. axial load is 2 shaft collars on each side of the bearing on the steel plate. the radial load is a jar coupler. the spider neoprene gasket is the piece between the two steel couplers that provides a bit of wiggle room between the propeller shaft and the electric motor shaft
Really great breakdown - thanks for the details! After watching a few of your videos, I decided to buy the same motor you have. it drives Monday! I have.a 1985 Morgan 36 with the original Yanmar diesel, and I can't wait to tear out the old fuel tank and engine! I have a few questions if you don't mind... 1. where did you get the drive shaft coupling? 2. Where did you get your motor mount? 3. Did you notice any weight distribution issues after you removed the original engine and fuel tank?
hi good luck on your project! i got my drive shaft jar coupler at princess auto. it was available on their website. i hand built/welded the motor mount myself. when i removed the fuel tank i gutted the boat and started over. i rebuilt the layout so my weight distribution was almost 2000 lbs lighter. i moved the water to the vberth and the batteries where the engine used to be so i could roughly keep the weight balanced port to starboard and bow to stern. my waterline is 3 inches lower with all the weight i removed so i can pile quite a bit more in for cruising provisions etc. now i have a galley i like and more room as i rebuild her. thx again for the note i hope you get your conversion working well for you!
Very interesting video. Thank you for documenting your work! From the computer side, I recall instructions that say to put the heat sink goop on really thin, as that improves the heat transfer. It would be interesting to compare the temperature of the controller vs the temperature of the coolant as it leaves the pick-up coils, and again after the radiator, to see where the heat transfer bottlenecks are.
thanks for the note! yes i think thin is better, enough to pick up any gaps. i did measure with the laser pickup thermometer but i wonder how accurate that is. the intake and outflow on the cooling plate is definitely lower but after getting the shaft aligned well with little resistance the heat stays pretty level on the controller. right now i have about a 12 to 14 degree difference measuring out vs in after cooling between 750 watts and 1700 watts.
@@TheNeds Regarding the laser thermometer... I have one, but find that the laser's spot isn't where the temperature is actually being sampled. At a range of a foot or so, they seem to be off by about a half inch. Makes it really hard to get a reading that I trust. I've since picked up a "Thermal Camera". I got the one from Acegmet, but there are many others. It's amazing how much more I learn about what's going on with a picture instead of just a point, even if the point were accurate. Not cheap, but worth it. It was quite a surprise, for example, seeing how hot some of my crimp connections were.
Great video!! How works with the hard conditions of sea and wind? What is the max speed to your boat? Appreciated!
Thanks a lot! I'm converting my Furia 33-foot sailing boat to an electrical engine using the Golden Motor kit and your videos are gold to me. Greetings from Barcelona, Spain.@@TheNeds
Looks peaceful
If you're trying to lower the temperature of the controller and motor more, wouldn't a larger volume of liquid and radiator be a better idea than more fans?
Have you been able to use the regen feature to be able to charge battery back when sailing. I would appreciate a lot that you would share with me all tips on this topic. Many thanks
i was unsuccessful with regen. i have that feature but the controller ‘beeps’ when regeneration is engaged which is very annoying. aside i experimented with it and couldn’t figure out how to get it to charge without beeping. if you go the same route and figure it out i would appreciate knowing how you got it to work. once i put enough panels in my setup generates more power from solar than i need (at the moment)
Hello, I am following your electric experience with a lot of interest. You inspired me so much, that I've decided to replace my old diesel engine by a Goldenmotor 10KW electric motor last spring. I sailed the whole summer with it, but I am still facing a regen problem.
Hope you're better now, and keep making progress. Am so impressed by the way you're explaining and giving updates on your electrical motor and cooling... am thinking of going electric but my vessel weights abt 7tons full keel (kgs) and I wonder what would you improve... larger motor or larger Vector controller? Am also in doubt mounting it by pooling or direct on shaft ... they have also the 20kw version available so the current draw should be lower? Have plenty questions and due my location in Canary Islands (Atlantic ocean)
thx for the note and i don’t recommend breaking your achilles lol. its been brutal. to choose the motor i went by HP mostly. the old atomic 4 had “30” horsepower but i have that in quotes. i estimated it at 1/3 as under normal operating speeds it was probably 10 hp due to the combustion engine wastes of power. the 10kw is about 13 but 85% efficient so it matched up perfectly for me. in fact because of the torque rating the 10 i would say is even better than my old gas engine. so the 20kw would be close to 26 hp. the controller i was told by golden motor has a recommended pairing with thr appropriate controller i would stick to their advice. best of luck to you!
@TheNeds wonderful thanks so much , will keep you posted of what they suggest me... Take care and blessings 🙌
@mr.crision thx for the feedback and good luck!
This is a very interesting video. I'm in the process of converting a 50' ~20000 lb catamaran to electric. I'm thinking about using 4 of these 6.5 kw motors to push it. I've noticed that electric motors are most efficient at like 20% of their output hence 4 motors running at 1 kw each would provide much more thrust than 1 motor running at 4 kw. Probably due to torque and cumulative prop size.
thank you for the comment and good luck on your project. At the time of my conversion i had little real world info available which is why i started creating these. also to document and share so i can remember what i did too ;) getting older lol. i have live test data in ep84 too. according to golden motor test curve chart peak efficiency is at 5000 watts for my motor but at 1800 watts its over 80% and i’ve found that 1600 to 1800 watts to be a good spot for speed, battery consumption etc. it seems thats the sweet spot for me but i often motor at 1000 watts and its still more efficient than my old atomic 4. i would concur with your 20% statement. you’d also have redundancy with multiple motors which is a great advantage. sometimes power in compared to power out isn’t the only factor as some props behave differently at certain speeds so gear ratio is important to consider as well. getting the rpm efficient and motor efficiency to align i think is a worthwhile goal to put time into. cheers and good luck!
@@TheNeds they say these motors are hermetically sealed. Nothing is ever maintenance free but what’s your impression on the build quality?
i bought in 2020. no maintenance. no wintering. motor feels solid. controller i had a bad one initially but after swapping no issues. wish it was smarter to get data like heat onto nema2000 network. thats something i have created workarounds for like sticking temp sensors on various parts. aside ill never go back to fuel but my style is im not in a hurry i’ll get there when i get there. going electric is not for everyone.
You might try tire cleaner. They seem to work great on white walls too. Not sure what material you have on your dingy
thx for the tip i didn’t think of trying that
