Electric Go-Kart

[Spartan117FS]

Who on earth wants an electric go kart?

Formula 250 Karts can go up to 180 miles per hour.

Gasoline engines for the win!

And that is a 1 cylinder 2 stroke 250cc engine =)

[EETechs]

@Spartan117FS How is a Formula 250 impressive when there are electric superbikes that can do 190 MPH? Have a look: /watch?v=b-SYq8H4xnI. I think you are still stuck in the past. It's not the 1980's, it is the year 2011.

[Spartan117FS]

@EETechs

The smell of fuel, the powerful loud exciting sound of a fuel engine. That's what makes motorsports racing, having fuel in your vains.

And your motorcycle example is poor, not to mention irrelevant. We are talking about go karts, I might as well pick a Formula 1 car or a jet fighter to this comparison if you are going to pick a motorcycle.

[EETechs]

@Spartan117FS So if your gas powered machine went 30 MPH, but made a loud noise and an electric powered machined went 160 MPH then you still would be more excited about the gas powered one? What you say makes no sense to me. Noise is noise I think. I guess I just do not share your passion.

[Spartan117FS]

@EETechs

What the fuck are you babbling about? I'm talking about fast fuel powered vehicles vs electric powered vehicles. And high powered fuel cars always sound better, smell better and are alot more exciting and much more powerful then any electric counterparts will be. I have no objections against making hybrid powered vehicles that add performance to the vehicle, like Formula 1 + KERS. However 100% electric just wont cut it.

[EETechs]

@Spartan117FS If combustion engines are more "powerful" as you say then how come I replaced a 5 hp electric motor on my air compressor with a 5 hp gas, but the 5 HP gas stalled well before it got up to the PSI that the electric motor did. And how come my 3 HP gas engine stalls in my torque video test vs. a 1.5 HP electric motor that did not stall. Maybe you mean lack of power because of the batteries in that they must limit the power so batteries do not die fast?

[Spartan117FS]

@EETechs

Combustion engines were designed to be big. Small combustion engines obviously fail.

Now try getting 2000 horse power out of an electric engine, batteries are another issue too.

[EETechs]

@Spartan117FS Electric motors in the industrial environment are available up to 100,000 HP. I can say for sure batteries suck bad though, and will continue to suck for the foreseeable future. So of course you should expect the electric motor to be bottle-necked by the batteries. A system is only as strong as its weakest link. Which are the batteries.

[traxxasmatt1]

how much money do you want for it

[RaceKill]

@traxxasmatt1

It's not for sale. Sorry...

[knowthytruth]

wow clean, nice and powerful..

[tomtom7773]

Nice kart but they drive it like a bunch of cocsax.

[RaceKill]

@tomtom7773

Then see our new video on a real go kart track. Check my channel out, and subscribe. ;-)

[shortyjk95]

Very very nice!!!

[parquor97]

where could i get one of these for a cheep price?

[Silverstreak350Z]

Any chance you can show it doing some actual driving and not just spinning out?

[FroggySR]

@Silverstreak350Z No not really. We still need to find a track.

[MrCode44]

i had a black one its soo coool

[ThePoliceofficer1234]

can you like make one more nd sell it too me ill buy it frm u for 800$

[0mcgl]

when i say efficiency. i ignore the actual term and say the weight of its fuel. and that is a problem i see with electric cars the batteries are so damn heavy. i mean come on 600 lbs of gasoline will last a damn long time batteries not so much

[Jiggle582]

have ever tryed actualy driving it other than get up to speed and then spining out WHT!

[gozerchris]

Nederland!!!!!!!!

[RaceKill]

@gozerchris

Denmark

[gozerchris]

@RaceKill where is it in Denmark?

[RaceKill]

@gozerchris Randers

[Desmonddd2002]

Hey hey nice go-kart :) Did you use a permanent magnet motor?

Do you prefer permanent Magnets motor or Universal motor.

Universal motor has high power to weight ratio and they are cheaper but i am not sure which one to use, and also is your controller using PWM?

[RaceKill]

@Desmonddd2002

Motor: L.M.C. 200D135

Motor Controller: Alltrax AXE 7245

We can pull 45 kW and 122 Nm out of this 11 kg motor. That is not so bad.

[EETechs]

@Desmonddd2002 If they are huge golf cart sized motors then they are called series wound DC motors, not universal motors, although they work the same way.

[terrettore]

compliments for your work. Have you ever driven it on a track?

[RaceKill]

@terrettore

Thanks.

We have not tried it on a track yet. But we have some plans on doing it once.

But right now are we rebuilding the control system with a new 6” touch display for driver information, and a 12” touch display as real time monitoring and service station. And a PLC for IO handling and monitoring. Its a real never ending project.

[RaceKill]

@terrettore

Thanks. Not yet right now are we chancing the control system, just for fun. We are to guys from the automation industry and we are making PLC control system and HMI touch panels on the cart and a remote HMI panel for real time monitoring.

[FearTygaToe]

what kinda engineer are you? and damnn ur my hero

[RaceKill]

@FearTygaToe

Thanks

Main Components:

Motor: L.M.C. 200D135

Motor Controller: Alltrax AXE 7245

Batteries: 6 X ODYSSEY PC925

Power Cables: 70mm2 CU

[Ebdan88]

What is the name of the motor you are using? thank's

[N3KR0MANTIXfan]

i have a question... whats the name of your chassis because i may have the same one and i want to buy the body kit for it but i just cant because i dnt know what kind of kart mines is.... thanks

[bryan7771]

sweet that means the cops cant do shit

[Illiamdra]

Mario Kart FTW

[Hogasofa]

isn't just cheaper to get a gas powered one?

[RaceKill]

@Hogasofa

Yes a gas powered will be cheaper, but not as fun to build. We are to power engineers that think its fun to make this cart.

[92rs25th]

@Hogasofa that and gas engines dont provide instant torque like that.

[Skytrainn]

thats sweet, but doing donuts is about all its good for cause all the power is converted to torque instantly, which is great for acceleration, but going 400 meters on that thing with the throttle wide open and it drains the battery mad quick

[RaceKill]

@Skytrainn

If the wheels is blocked the batteries is drained in about 3 minutes. But aggressive driving time is about 15 to 20 minutes.

[1colombia1980]

GREAT WORK, What is exactly the function of capacitors? And how many volts are the motor?

[RaceKill]

@1colombia1980

The function for the capacitors was to delver the peak current and take some of the stress off the batteries. In some of my other videos you can see that the capacitors is removed and a extra battery is installed. The maximum power is about 600 Amps at 86 Volts makes 51kW and 110Nm.

[lexichronicle]

smart move adding the bypass caps!

[FroggySR]

6Kw with the right gearing should make it drive, but with the acceleration of a rental gocart :-(. We use in total around 5000 usd. Batteries alone is 1450 usd.

[xXwhygodwhyXx]

where did you get the frame?

[RaceKill]

Its a used second hand race kart.

See the video with 7 batteries instead of 6, that much more fun. In my videos...

[talibanrules]

were you get the motor ?

[chrisdude1001]

i am building a version of that

it is like a t-rex

(for people who dont know what a t rex is:

three wheeled vehicle with two fron wheels and one in the back)

[K0xd]

Thats exectly what i want to make!

[davison1021]

howd u connect the batteries regular or -+-+-+

[RaceKill]

The batteries is connected in series -+-+-+-+-+-+

[amando96]

series give you speed, but paralell give you run time??

[wires99]

More batteries in parallel give you more current and torque, more in series give you higher voltage and speed.

Ha ha. Check out my video (watch?v=CykCx1xLEzQ) at 00:48. I didn't know there was a SONG about it. LOL.

Seriously though, nice work.  I should have started with a normal racing frame instead of building mine from scratch. I've also considered upgrading NK2 to the 7245 - it's amazing what a 50% increase in power can do.

[gmoney2896]

what type of batteries are those, and were did you get them

[RaceKill]

The batteries is ODYSSEY PC925. The type is AGM its low cost and very powerful. It can handle 925A in 5 sec.

[ninjamonkeymonster]

odysseys are very nice batterys!

...but expensive

[RaceKill]

Compared to what?

Lithium batteries are 5 to 10 times more expensive!

[ninjamonkeymonster]

just to cheepo china made SLA batterys

( $20-30 each )

odysseys are tons better batterys from what i hear and are $100-200 each

[gmoney2896]

About how fast does your go kart go??

[RaceKill]

About 70 - 75 km/h

[skootb2]

how much was the motor u brought

[RaceKill]

The motor cost about £900 and the speed controller about £450. We found out that the 200D135 was the right choice for our project. We was looking at cost, power and weight.

[skootb2]

are there any other fast motors for cheap that aren't discontinued

[RaceKill]

Yes. The frame is from a used gas powered kart.

[smii3]

does it have reverse?

[RaceKill]

Only forward drive.

[smii3]

did you convert it (from a gas one) because im going to buy a frame of a racing go kart, but add an electric motor

[RaceKill]

The motor is from L.M.C.

Lynch Motor Company Ltd

[bimbolino14]

wheres the motor from?
