Big Boy Feigao 580L

Wouldn't one of these work? http://www.offshoreelectrics.com/pro...?prod=gnd-4198

Hmm.. My 31" Olympia Hydro may need a new power plant.

The 580 is listed at 1800 W
1800 devided by 22.2V = 81A max

The KB45 is listed at 3000W
3000 devided by 22.2V = 135A max

It would seem to my that the KB45 would be a better motor with more power.
Also you can get a water jacket on it to keep it cool.

My first thought on this data is that the KB motor is listing it's Burst max W, and the Fiego is listing it's continuous W... I may be wrong...

I also bet that the Fiego is a better quality motor than the KB.... I've heard the KB motors don't perform up to their rated specs, but that's just what I've heard... I've never tried one...

[ReddyWatts]

The KB45 is 1500 watts continuous with water cooling/ 2700 watts 30 second burst.

So I am guessing the Feigao 580L is 1800 watts continuous with water cooling / 3000 watts 30 second burst.

[TRUCKPULL]

This is taken from the offshore Website
It clearly says 3000W

How can you say it is 1800 watts continuous with water cooling,
When you can not put a water jacket on it with the screw heads on both ends.

remove screws on one end...install water jacket..reinstall previously removed screws..done...

That all sounds good, Have you done it yet??
Are the screws put in with thread lock??
Did you strip the screw heads trying to get them out??
Did they stay tight after you put them back in??

Big question is does the water jacket fit without leaks??

Larry

[ReddyWatts]

Geeeez.....never been threatened on here before about a private message.

You are correct. I did not mean to contradict your statement. That is just what I had personally recommended for KB motor from experience and was guessing at the 580L.

If this is your own opion then post it that way.

Put this on the web site or I will.

Why send me a PM saying that your numbers are your own personal opion.
The numbers I posted are posted on the Offshore Web Site.

You posted some numbers, but forgot to tell everone that they are your personal opion.

You must remember that a lot of other people read this to try to find true Info.

I respect Steven enough to believe that the info on his web site is true.

My threat as you call it was to state that your numbers are only your personal
opion.

[ReddyWatts]

Cause its best to keep this kind of chatter off the site.

Agreed! Now back to the subject at the matter and keep the threats and distasteful comment in private or somewheres else.


Boy that 580L looks some good!!
I cant wait to hear some results.

Sweet Buddha...It'a simple piece of machinery...why all the angst
In the absolute worst case Screws can be removed even if locked into place via cyanoacrylates with a little heat...ruined threads can be retapped and screws replaced.
You'd think I was promoting kitchen table brain surgery

First let me say that I would not have offered and marketed a motor for our boating community that would not accept some sort of water cooling.

The below picture was not going to be posted but I thought since some have had some questions I would post it. The reason for not posting is that the jacket is rather tight, but will fit with patience. I hope to have something along the lines of Feigao XL jacket/ Neu jackets in a month or so.

Why BLUE?? LOL

Keep up the good work Steven!!

Also, screws are removed easily with a quality 1.5mm driver. End bells come right off and can use these bearings

Thank You for that report.
It is intresting that they use the big 6mm bearings with the 5mm output shaft.
I like the Octura Flex Hex 5mm couplers more then the set screw type (6mm).

The shaft is 6mm with a optional 5mm output shaft.
I opted for them this way. Because of the more coupler options.

Good call on that one!

The cooling jacket you showed, is that a new jacket or the same KB45 jacket? Looks similar.

[Steven Vaccaro]

Thats a kb45 jacket. The OSE Feigao 580 L jacket will look similar to this.

[TRUCKPULL]

Now that looks good.

larry-

i will have you Ply wood.

[robby76]

would like to know from the "sport" pros if this motor would be a good candidate for a twin 53 or 58 inch cat using one of these hulls:

the gaser version run around 13,000 rpm using somewhere around a 65 to 70mm prop.

how could this be set up?

would be a twin drive LiPos

[TRUCKPULL]

For a hull that size you would want to run 8 to 10S
8S with a 850KV motor would be 25,000 RPM and smaller props.

I got my 580 6L today. Good bearings and balance. The phase wires are roughly 10ga. It looks great on the outside.

So I opened it up and it got better. The winding are evenly compressed with the coils nicely lined up (no wandering at all). Lots of copper in this motor.

The rotor is well balanced with the magnets mounted on an 8mm shaft that is turned down to 6mm for the bearings and again for the 5mm output shaft. Some how I don't think we have to worry about the shaft whipping at high RPM.

Now for some good weather to go testing. Oops, gotta build the boat first.

P.S. The KB45 water jacket fits fine.

The bearings are still the lesser expensive Asian ones. Some are better then others. But in the end a good set of bearings will be a thing to consider.

[Boatman]

How many of these things sold? Does anyone have anything good or bad with experience yet? I would like to run one on 8S. It will be my first HV setup and in a 36" glass cat boat. Very light.

[ReddyWatts]

Any test results of the 580L???
