Yes, it's all dependent on the speed you wish to hit. If you don't care about speed 500w will be enough. RPM range for submerged is 10k-25k. Your build will be on the lower end of this range and possibly even lower depending on what your goals are. 60in is huge.

Hi, I have recently found this channel and like the explanations about motor KV but I am missing something I see everytime I build a RC jet drive powered boat. I will give an exact example I measured: I tested a boat with the completely same jet pump (same propeller, same load) with two brushless motors, both 3660 size, rated for the same power output, on 4S. The first motor with 1700kv spinned the pump up to 20k RPM and pulled 20 amps. The second 3180kv motor spinned the pump almost to the exact same RPM but consumed 40 amps - outputting the exact same power but being two times less efficient. The thing I am curious about is this RPM drop under load. With no load, the first motor would spin at 25k RPM, the second would spin at 48k RPM, but both drop to 20k RPM when loaded. So: How is the RPM drop related to efficiency? Why is the lower KV motor more efficient?

I'm still trying to figure out how to do this but basically you need to know your final drive gear ratio Once you know that then you take your volts x cells x kv for your motor rpm then take rpm ÷ final drive for axle rpm. And as for the speed you would also need to figure out how to convert wheel speed to mph or kmph and that usually depends on wheel size but thats all I know best of luck

@RCexplained4 жыл бұрын
Hi Isuru, this comes up quite often and will be a video I make in the distant future. The wires are not as thin as you may think. The reason is because of the length of the wire. In a typical house in North America, we use 12 or 14 gauge wire for about 15A of current. The difference here is the wire is running well over 60ft in length. Our ESC's and motor's using the same gauge of wire are usually less than 2ft in length. A huge difference. This is why they can be rated for a much higher current then you may be use to. In RC, all the current ratings you see are indeed in amps. What you need to watch out for is continuous ratings vs peak ratings. This is very important.

Have you measured how much current (amps) the motor draws at full power. The electronic speed controller reduces the output power if the motor draws too much current. My suggestions are to measure how much current ist flowing and use an ESC with higher amperage. I had a similar problem, in my case the cut-off voltage in the ESC was set to high and the motor didn't run at full speed. At half throttle the ESC switches off the motor. My solution was to buy a hobbywing program card and set a lower cut-off voltage. My setup Lipo: HRB Power 12S 6000 mAh 50C (4x3S lipo), ESC: Hobbywing Flyfun v5 130A Brushless motor: Eagle Power EA98 KV120 propeller: 3080 inch carbon fiber propeller.

Probably drawing too much current, either run a smaller prop or get an esc to run higher current. You can also try running a much smaller prop or less agreesive pitch but using 3S instead of a 2S to achive a similar speed, that way your using higher voltage to achive the same power instead of current draw also note that method only works when you're trying to just get the same amount of power from higher voltage either by smaller prop, gearing down or using a lower kV motor, if your going up in voltage to achive higher speeds and power your over current problem will not go away and may even get worse.

I know the motor can handle this kind of RPM since it was previously used on this voltage with an airplane propeller at 200+amps. The current car has an 18t pinion. I can fit a 13T (maybe 11T with modification). Maths says I should be close so ok - 3s x 3200 x 18 = 172800 vs 6s x 2650 x 15 = 206700 - the differential between the 2 in rpm at the drive is around 19-20%, the differential in motor size/surface area is >23%. How about with a 75% throttle limit? I understand the electronics but I don't understand drive losses and relative loads in rc cars.

@@RCexplained Apologies, I was doing cells x kv x pinion size for a comparative value at the spur, all other variables are the same. 18T vs 13T is the available pinion for each, I can go down to a 13T and a 18T is known working for the existing setup. I'm trying to close the relative difference in motor RPM with the gear ratio on the pinions. (3s x 3200 vs 6s x 2650 then x by the pinion teeth). On a plane I'd just prop down and use ecalc to guestimate where to start, I don't know how much changing the gearing on a car deloads the motor. I watched your other high KV motor video, I understand trying to drive gearing too fast can be amp hungry. There's not much data around quantifying that, car guys don't seem to be that into electronics and data logging.

I've been fixing up my oldest RC car that I got back in highschool. This thing overheated and broke CONSTANTLY to the point that it got so frustrating that I completely quit the hobby until a few months ago. Now with some hindsight and maturity, I see that it was probably a poor idea to "upgrade" the motor by switching to one of the same size but moving from 3300kv to 5700kv, while at the same time moving from the stock 23t pinion to a 29t, while also at the same time moving from 2s to 3s. Now I see that I was essentially setting it up to be a speed run car, because yeah it would completely overheat in about 3 minutes of running but damn could it go fast in a straight line (before inevitably slamming into a curb) At this point im still using the 5700kv motor, but switched the pinion down to a 17t and and now its a 2s car. It works pretty fantastic now. I really wish there was a youtuber like you back in the day, would have saved me so much trouble haha

Well I’m defending the 6s battery. You could change how it’s wired and then say “ we can run the 6s for this application “.
@RCexplained4 жыл бұрын
My 6s battery would have to be cut in order to rewire it to another configuration. It is just one pack. Perhaps you are talking about having 2 3s packs?

I think I missed the point that the motor is getting this energy regardless. It’s about the motor .

My wife said your video is non sense: The biggest is better, all other parameters are driver skill or loosers complaining with maths why they have a little one. If you do not have enough room on your car you can even use a motor bigger than your car using a secret pro tip: Put the motor (or two motors) in a big trailer.

I like to think bigger is better, however a kraton exb with a 1/5 800kv motor although will work will sure make the truck go like stink but it will handle like crap and be so heavy that a remotely heavy crash will likely just break the truck. You do need a good middle ground and not an extreme at either end.

@@markmmm1737 Of course you have to adapt the car to the big motor. If someone is complaining of a big motor: This mean he did not found solutions for his weak roller or weak tires or weak transmission and it does not mean the big motor is the trouble. For my motor I had to find glue to stick my tires on the road because tires where spinning even at high speed. The big motor was not the trouble, the trouble was the tires. Now I use motorcycle chain wax on my foam tires: It really make noise when I unglue it from the road (seriously). :-)

Your math is based on batteries ran in series. Run series and parallel together and your rpm will drop because the voltage will decrease and mah will increase right? I’m stoned sry man.
@RCexplained4 жыл бұрын
If you run lower voltage, yes RPM will drop.

you gave some false facts, if motor has 2000w at 98 amps it means there is 20.4 v, P=UxI, so U=P/I, and here you started to fail, now you should found resistance of motor and it is if I=U/R, then is R=U/I, what gives R=0,208 ohms, so with less voltage you can not get more ampers than 98, so your calculation for 14.8 v and 11. 1 v are totally wrong, at 14.8 v I=71A, and at 11.1 v I=53.4 A, did you have in elementary school basics of electricity, i had
@BenjaminMarquez-q2g11 ай бұрын
Then you should know that it’s not written P=UxI (like you did because it’s confusing and wrong) it’s simply P=UI. Even worse you are wrong. You are using the resistance of something that has a voltage of 20.4 on a calculation on a problem with 14.8 volts. Of course when you drop in voltage current increases. Elementary boi.
@makantahi373111 ай бұрын
@@BenjaminMarquez-q2g you are wrong , how you can get more current with less voltage, with same resistance,(voltage pushes current), this motor has peak power at 98A and voltage at 5S, if you want same power with less voltage, motor must be designed with thicker and shorter wires to get less resistance, then tesla would not have 800v in car because your logic would say that 400 or 600v is enough, go back to school

All fine and dandy if the motor manufacture has the max RPM noted.
