12 kw rc motor

[gwhy!]

I wish I can get my hands on one of these motors , I have asked but no joy

[zEEz]

perhaps we should contact this chinese company if we want to be extra-fast

http://yuneec.com/PowerMotor.html

the limit is that their motor and controller are targeted to aircraft use,
so we would have the same recurrent problem: they are not suited to
tolerate the high load at low rpm we need ... BOOOOOOOOMMMM

have fun

Is this topic really DEAD? No COLOSSUS talks anymore????

Is this topic really DEAD? No COLOSSUS talks anymore????

Im going through the very slow process of building a controller from scratch! And splinter is using a kelly so.... Whats there to talk about we are at the mercy of mosfets that cant handle colossus!

Weppppp, Arlo, a lot to talk about it would be ....

Some months ago I heard about a website to sell colossus online, about an imminent
ultimate version for people willing to buy, a matched controller tested in Croatia ....

But after that just Dead Forum and nobody around

By the way, Arlo, how about the super-fets from lfp you wanted to use?

have fun!

In my very early stages of controller testing I lernt how to blow up over 1000$ worth of megafets in seconds and it wasnt even colossus's fault! Dont worry I will have colossus running at very hi power levels it just takes time. Im building a bench for my lab and am lerning to program PIC processors and building an open source controller see "Not simple controller thread" It will come together it just takes time!

Seems like the Croatian dudes are busy with the RIMAC Concept One. I hope to get a hold of them again soon.

As for making the motor run. I am using a Kelly 500amp 72volt controller on my bike and I am doing test runs on the bike to confirm the setup.
Here is the setup


Here is a ride up and down the street


Here is a longer ride getting up to 70km/h


Note I am running a 30ah Headway pack and I am limiting battery current due to that. With the last tweaks (controller settings and Burtie's Timing Adjuster fitted and dialed in) I am now getting up to 85km/h with 100amp draw on the battery that is around 7.6 Kw assuming my battery pack is holding up to 76volts (need to add a volt meter for testing).

I am yet to have the Kelly cut out or blow up.

[gwhy!]

I would still very much like to get hold of one of these motors, So is it only two of these motors that is being played with on this forum ?. Do the motors still exist ?. Not much point trying to work out a controller for the motor if no one can get hold of it.

[zEEz]

This is right: the RIMAC concept car has taken the lights away from
the COLOSSUS MOTOR .. THAT MAKE SENSE !!! The guys have bigger things ...

.... so we wait and see what will happen next!

Thanks from the updates from arlo and splinter .... 7kW is a good output
for that motor if the system is reliable and working fine ...

have fun!

Note I have not hooked up the water cooling on this yet so until I get my full battery pack and the cooling I will not be pushing it much harder.

7kW stable no plasma without water cooling and chopped battery?
So far so good ..... I would say it is working REALLY fine ...

Wish I could experiment with something like this once in the near future!

have lots of fun!

[Arlo1]

I havent looked to much at the RIMAC concept one but.... HOLY SHIT I wana sell every thing I own that burns gas and make an electric car like that! IS it possible it uses 4 giant versions of colossus?

[markobetti]

Splinter - great stuff !
I am not working on RIMAC project..Hal is ... Two big giant motors are not in anyway affiliated with colossus , those motors are by the way inrunners as i can see. Colossus motors are still in test mode (we didnt run it with new controller), and hal is busy so he didnt have time to put it on Egenric. Arlo and Splinter have the motors since they are the first two guys who wanted them badly enough and had experience or friends that can help if something goes wrong. We are working on them , i have made something new ; so i am waiting for factory to send it a . After 3 months we will start taking orders i think. Just give us time to get all bugs controller-motor figured out .

[markobetti]

Splint , do you have cycle analyst ? Some readings from it ?...would be good

[SplinterOz]

I am not running the Cycle Analyst I have as it is a direct plugin model and that does not work with the Kelly.
However I am going to rig up a small camera, volt meter, amp meter and GPS speedo so you can all see how it is going. Give me a day or so.

Ah, good, thanx for the info! Just let us know when Christmas Orders will start !!!

Shitzz..if you were in Croatia , me and my pal Grga would put so many instruments on your motorbike from cycle analyst to couple of dozen volt meters that you would look like New Year crithsmas in New York.. Doesent anybody have the version you need near you - just for you to abuse it for a while ..? Basically Cycle analyst records also peak power , my other instruments dont do that... Well i know one that is being made here in Croatia , it will record anything....but still in early stages...

If you follow the wiring you can open up the Kelly and install the CA to work with it. Just have to cut the end of the CA wire plug off and solder the wires where they need to go on the circuit board.

Arlo1, I am quite happy to leave my working and in warranty Kelly intact. I might be able to get hold of a cycle analyst and shunt later this week. That would allow some real data.
However I can get nearly all the same info with a amp meter (already on the bike), speedo (have to put on the magnet) and volt meter. That will give me the instantaneous usage at any time for any given speed. I just don't know Wh per km not a big deal at the moment.

Yeh if you have the data you need its not worth the hasle. Have you got something to watch phase amps?

I think I can strap a clamp meter onto the bike for that measurement... might be hard to get it into the same camera shot though.

[SplinterOz]

Here is the bike running.

Note the 1030 is the battery Amps multiplied by 10, using a neat gizmo from Zeva to drive the tacho.

So for the hard of seeing...
78km/h
67 Volts (boy these headways sag)
103 amps

This makes for 6.9Kw for 78Km/h not too bad.

[zEEz]

Hey SplinterOz!
Your motorbike is already useable for short range commuting ... that is Great!
are you planning to add more headways???

I wonder how fast you could go with full motor current and Liquid Cooling ...
130kmph should be there ...

Do you plan to make it street legal? How it is with regulations in Australia?

have fun!

Here is the link to my build thread... http://endless-sphere.com/forums/viewtopic.php?f=10&t=25697.
But to answer your questions...
24S5P of Headway's 10ah
Full motor current and water cooling is in the works.
The ADR (Australian Design Rules) have a section on modified motorcycle and another on EV conversions. I just have to comply and get an Engineer's Certificate.

Already having fun.

Great news! It is a pity that in Europe the modifications to EV are more difficult to legalize

I understand your fun and the fact that with 50Ah-75v battery it can last enough long
between each charge

have fun!
