Of course you'll need a double bearing for axial loads in forward and reverse... Sendt fra Yahoo Mail p? Android P? tir., den 16. mar. 2021 klokken 10:47, Carsten via

Hi, Steve Consider to make your thrust bearing with a high quality spherical roller thrust bearing, eg. of SKF brand. This can accept torsional forces much better than ball thrust bearings.Then you

The other mfg of thrust bearings I considered is Aquadrive. I think with both Python Drive and Aquadrive you can also buy a thrust bearing without the CV shaft and have them machine to adapt to

I used a Python Drive thrust bearing and CV shaft combination. There is another similar mfg, but i can’t recall the name. The bearing at the motor plate is a radial support bearing. The CV shaft

I'm in the process of planning and installing a Hyper-9 motor at 154V with a battery bank of 48 280Ah 3.2V LiFePO4 batteries I received from China. The motor is rated to be plenty powerful to replace

Consider that you want to operate your motor in the sweet spot which is usually somewhere close to full throttle. If you overpower too much you might be running in the 20-40% capacity range which is

ratios vs heat: My 10 kw motor can spin 5000 + rpm Intuitively I topped my ratio at 2700 ( for longevity i thought ) But at slower rpm the cooling fan is also slower = less cooling . I mostly use the

I love it! Great pictures on your website as well. Best of luck on your work this spring! When the wind is up do those pole-mounted solar panel produce a lot of drag?

Randy, I can give you a benchmark for how LOW you can possibly go.? I've been pushing a 45',? 20 ton, concrete bilge keel hull with a 48V, roughly 8 kW, "golf cart motor on steroids" for about 8

The ME1616 with the Sevcon Gen 4 Size 6 will give you 24kw of power continuously (48kw peak) at 96v. I'm building my conversion with 2 of them (48kw continuous, 96kw peak) via saildrives on my 34' 4.5

Dan, The reduction ratio was an experiment. I started with 2.34:1.0 which gave too much motor current at too low motor voltage/speed. I then tried 3.00:1.00 which was too far the other way. I settled

Thanks for the numbers. Some more questions. What did you do for a thrust bearing? And where did you source the pulleys? They look almost like they could be stainless in your photo. Do you recall the

Dan, Can’t recall the belt wrap percentage. I did consider this in my design and think I’m likely under the 30%, or close to it. I remember it was right on the edge. It’s been 7 years, or so

This is a very tidy installation. The only thing I wonder about is the engagement of the belt on the prop shaft toothed pulley. It does not look like enough but it is hard to tell in the photo. I

Ryan,2 Sevcon controllers and 2 ME0913 motors electrically separate. One throttle with the signal sent to both controllers. Actually I have 2 throttles, but one is a spare. It can be quickly put in

I think if you look at the Rigging Doctor motor videos you get a look at the drive system. Looks like just two simple belt drives to the output shaft. https://www.youtube.com/watch?v=sMxBC2oE3jo I

Thanks Christopher! Do you have a photo of the drivetrain? It sounds like you have them in mechanical parallel but electrically separated (two controllers)? Do you use a single throttle to drive the

I have 2 X 10kw Thunderstruck kits in my Morgan Out Island 41. I built my own reduction system to parallel the motors using one belt. I have a 22KWh battery bank at 48V. I have a 4.2 kw/120VAC Fisher

Thanks Dan, this is helpful! I wonder, are electric yacht using a differential or just two pulleys on the same output shaft? The positioning of the motors makes it look like they are using a

I have a 46' sailboat that I'm converting to electric. I have the ac35 from thunderstruck which I believe is 32kw motor. I'm letting it with a 72v battery bank. The guys at thunderstruck told me that
