The Feigao motor has arrived. The 580L motors look rather impressive. I will have some pictures and sales info by the end of today.

580l??? Is that like the size of a 600 brushed motor?

580L? A quick search show it to be 45x50 in size.

"Ferrous loss free brushless motor, 6 poles. World first 580L size ferrous loss free BL motor."


6-pole motor should be nice in a 45mm diameter.

Also, the diameter larger requires a larger water jacket. Any plans of one, or will the KB45 heatsink work?

Never mind. I looked it up. It's a 45mm can. Should be a torque monster!!!!!

Nope, not that one. Its a new motor, not on their site yet. 2 poles. A water jacket for it is in the works.

Steven,

I take it that this motor uses the same mounting bolt pattern as a say the KB45.

Flying Scotsman
11-16-2008, 01:01 PM
Steven, if I removed what look like allen head screws on one end, would the Kb45 water jacket fit?
Or would that be a dumb move?

Duggie, I'm nots sure on the fit, but I will try. Even with the jacket we make the screws will have to be removed to get it to fit.

I just received the 580 6L winds also. Should make a good 4s motor.

whats the advantage of using the new 580 l as opposed to the 540 xl 8 ? i am building an mm hull and want to get the best for the buc. so when i pick a motor (in my budget zone) i awant to make the right choice. will a hydra 120 esc be good enough for the 580 or not? still a newbie so now the watt thing has me a bit confused. 8xl, 1000 watt max 580 l, 1400 to 1800 max. batteries determine watts being applied or what? really want to understand :doh:

Steven Vaccaro
11-18-2008, 01:40 PM
volts x amps = watts. You know volts from the batteries you use. The amount of amps is determined by the motor and load(prop size). The bigger the prop, the more load. So a motor can be run at varying loads. For example I have run the same 540xl motor at 40amp to 80 amps, depending on what I was trying to accomplish.

The 580L has a weight advantage over the 540XL. The heavier the motor, the more torque is will have.

These are all general thoughts. There are very thick book discussing the finer details that spin my head.

ED66677
11-18-2008, 01:51 PM
The 580 has bigger can diameter and more or less same rotor lengh than the 540XL, so it will have more torque

sewerpit
11-18-2008, 01:57 PM
thanks guys you answered my question, so an 8xl with a max of 83amps and 7.4 volts would yeild 614 watts as compaired to a 580 -8 with a max of 91 amps and 7.4 volts yeilding 637 amps, so the 580 can be run using 2 4s in series to get 14.8 x 93max amps = 1346 watts still under the min 1400 to 1800 watt min/max . 0r should the 4s be run parallel to keep the volt down. does what im saying make sense or am i just a little slow lol

ED66677
11-18-2008, 02:30 PM
Two 4S in series will give 2x4x3.7=29.6V!!!... Assuming you talk about 4S lipo's with nominal voltage per cell of 3.7V
I guess you ment two 4S in parallel to double available max amp from batteries?

sewerpit
11-18-2008, 02:47 PM
sorry, yes i was using nimh volts so 2-4s 3300 in parallel would give me how many watts if the 580 8 has a 91 amp max

Flying Scotsman
11-18-2008, 03:07 PM
Sewerpit, do not get too concerned with the maths, as it all goes out the window with the prop you choose and the setup. For a hydro 120 I would select a 9XL for 4S a 12XL for 5s. as a max
Conservative...yes...dependant on your prop, boat length,width and style. Those are the factors that count. Your mean machine will not benefit from this new motor...My 2 cents

Douggie

ED66677
11-18-2008, 03:08 PM
4S lipo's (14.8V) the 580-8L will give you 4x3.7x91=1346Watts

sewerpit
11-18-2008, 03:22 PM
thanks to both of you for your simple answer, makes it sooo much easier for me. 9xl it is . will keep you all posted once my build begins :thumbup: ill get to proper prop when that time comes :confused1:

ED66677
11-18-2008, 03:38 PM
Last thing, I'm sure Douggie and others will agree, you cannot really compare a 540-8XL to a 580-8L...
first the weight, a 540-8XL will just fit, for example, in a 29" mono, while she would look like a submarine with the 580-8L!
second the torque, the 580-8L will have something like 30% extra torque compared to the 540-8XL, it will be able to spin a much bigger prop and move a much bigger hull!

Good job getting this motor, Steve. I run a Lehner 2250 in my P mono, which is only 1 oz heavier than this Feigao.

I bet this motor, X445 prop, a CC120 or ETTI 150, Titan 33 or DF 33 will run just fine on a 1P setup and handle a 1 mi race heat.

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...

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.

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.

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??

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.

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.

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.

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
11-20-2008, 09:28 PM
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.

I ran the 580L 6T on my XT460 Tunnel hull yesterday. The motor is an animal, far too much power for the 7.5 sized tunnel hull. Folded the bladed over on a heat treated octura 1450, huge amounts of torque.

Setup:
Lee Craft XT460 tunnel
Hyperformance 7.5cc bullet drive
4S2P 4500 30C elite cells
CC Hydra 240
580L 6T
Prather S235

Temps after 6 laps and a mill lap:
Motor-115f
ESC-cold
Cells-120f
6100 mah used.

I think a 7T will be better on this boat. Unbelievable performance for the money. The 6T is going in a rigger next. The 6T and 7T are probably the ultimate budget P class competition motors. I certainly wouldn't feel like I was at a disadvantage running them against more expensive options. Upgraded bearings aren't a bad option.

Here's pis of the boat and install. The hull is 33 7/8" long. It's 41" from the nose to the end of the cavitation plate. The 580L is a big motor and it looks small on this setup.

I milled holes in both the endbells so that it would drain after the inevitable flips and flyoffs.

I'm going to swap the 6T for a 7T and tune it to run 2 lap time trials. I can only imagine the carnage of a 6 boat heat of these things.

So what was the consensus on this? I ask because I am about to build a 29" sprint cat and thought for a moment about the 580L. It initially would seem that this motor is to big for a 30" hull but you, Heath, has been able to make this work. Any thoughts from anyone else? thx

I am considering this motor for my Triton build. Any thoughts? overkill? after quite a bit of researching I found this hull was designed to handle more power than most people put in it.
