KB45-08L 2300kv Brushless Inrunner

You can expect 80-90 amps draw on a motor like this.

I don't recommend at all this motor on a car on 4s. Take a classic brushless 3674 or a 4074.

Sorry but I take KB45-08XL 1600KV 3,528KW

The boat is a 120cm speed boat with a very deep V-Hull amd the weight is 8kg.

Another motor is the XK4082 - 1600KV perfectly for the vanquish and the motor is still cold! The combination with a 45mm 2blade screw is really the BEST MIX at all!

No. On 3s amps go to 130A (127 mm edf) So, 100 amp esc will burn

red is positive, black is negative and white goes into the last plug! hope this helps

The hobbyking 150A ESC has orange yellow and blue wires???

 Hobbyisity 204 points

are there little symbols near where the wires come out on your motor??

 Jslasher 7 points

This is sensorless correct?

 Hobbyisity 204 points

it could be with the white cable

 David 7 points

the wire order does not matter, red is not positive, black not negative. it is essentially a 3 phase motor. hook it up, if it runs backwards, reverse any 2 wires and it will run forwards.

 Michael2 158 points

You make a short in The MOTOR!! If it is too hot the lack is burning and you have contact to other cables from induction

Hola! El voltage mximo que soporta el motor son 36v as que lo mximo que podras usar es una lipo de 8 celdas. Por lo que vi en los comentarios, la mayora lo usan con 5s o 6s de 4500mAh. Las caractersticas son las siguientes: 2300rpm/v, 3439watts, eje de 6mm y voltage mximo de 36. Espero te sirva la info. Saludos!

Ten en cuenta que para consumir 3439W a 36V el motor necesita 95A. Cada celda de Li da 3.6V o 3.7V, así que podrías usar hasta 10 celdas. Lo más seguro es suponer que la potencia estipulada es para 36V y 95A. No te recomendaría superar los 95A. Yo medí la resistencia de los bobinados y es de 25mOhm.

Good cooling and I think it will work!

if you use this motor with a traxxas slash, it will fly without wings. super powerful.

I would say yes, but you must use a good watercooling and 1 of the turnigy marine 180 A ESC

the novak hv is only for sensored motors!

If you do try this i recomend at least a 1/2" thick plexiglass bullet proof wall inbetween the motor and every living creature you want unhurt.
be sure to make a video so you don't have to explain to the doctor what happened. Maybe have a fire extinguisher handy.

If it stays together for more than 5 seconds, i'll be impressed.

 scarletboa 350 points

yes, a 44mm heatsink will fit this motor just fine.

 jvgjvg 107 points

how many poles has this motor??

 Micho69 277 points

2 poles

 gadelavega 2 points

I think it is a 3 pole motor: it has 3 wires and you can feel it "clogging" six times when you spin it one turn by hand.

 gadelavega 2 points

Consider that this is a 3.5kW motor, even 1pcnt loss means 35W. That's a small incandescent light bulb!

 gadelavega 2 points

The motor is rated for 3.5kW at 36V which means 95A. I wouldn't go over that.

 Deryn 101 points

What technical specs do you need that are not listed?

 dredr 59 points

how many turns ? is voltage of 22,2 v enough to run it ? how many milimeters between the mounting holes ?

thanks for your answer

 Deryn 101 points

This one is an 8 turn motor (the number before the 'L' or 'XL' is the number of turns).
6S (22.2v) will run it, and produce big power.
4S (14.8v) would even be enough to run it, and run it well - comparable to a nitro engine with equal tooth pinion/clutchbell.
The d.e.s.c.r.i.p.t.i.o.n states 36v max, but a more realistic maximum would be 26v (7S).
Not sure of the mounting hole distance, but from the picture I would guess from 28-30mm.

 dredr 59 points

Could you please tell me the the maximal Ampere when it runs with 6s lipo. i plan to use a 100 Ampere esc would this be enough ?

with best regards
daniel

 scarletboa 350 points

this motor runs best on 4s lipo and has 30mm spacing between the bolt holes. i have a couple KB motors and as long as you don't go over 40k rpm with them, they don't get hot and can pull a huge load. if the motor is too hot, but the esc is cool or warm, you are likely undergeared. in 1/8 rc trucks, gear for 40-45mph.

8 turns , water cooled mount water cooled jacket is needed.
