Brushless motor sizes and numbering explained.

[@helicopter7730]

Its really so simple. Apart from the physical size specification and shaft diameter, all that manufacturers need to state is how much Torque, at what RPM and how much electrical Power is been consumed. The rest can be calculated mathematically. I have never understood the purpose behind the kV ratings which indicate motor RPM versus applied voltage, as they are meaningless entities without a known load been applied. Just specify the motors Torque, RPM and Power consumption, and the job is done. The physical motor size is not always indicative of how much work it can do. One day we may see this happen, and most of the questions as to what motor does what will no longer be asked !

[@cimjohansson4878]

so, you will just gear it for correct top speed or adjust how many cells you run? i prefer to know the KV so i can run my 6S and a resonable pinion and still get the right setup. imagine having a 4000 kv motor and buying a new one with 1500 kv just because the torque, max rpm and watt is what you look for. that will be a slow car x)

You wouldn’t believe me if I told you, I’ve custom fabed insane blue printed motors for drag bikes and motorcycle stunt bikes professional drag racing, also built million dollar sport cars, this is the first time I took the time to figure out what the sizes of Rc motors since 1982! I just eye ball it and go. I so appreciate you breaking it down. I have over a hundred rc motors laying around and a caliper right next to them. I just measured one and yup 56118 is 56mm thick, 118 long! How I build hundred of rc’s with never checking and it works, is beyond me. Dont tell anyone I didn’t know this. 🤣🤘👊🙏🏆

Great job. I finally got some answers I was searching for. Mainly motor can size. Most vendors list the shaft size but not the can size. Mainly the diameter. I just measured the OD of a 380 brushed motor and it is 24mm. So now I can simply look for a 2435 brushless motor. It would be nice if vendors included the dimensions of their motors in their descriptions. Again thanks for this valuable information.

​@bharris0128 the numbers on old kyosho motors indeed showed how long they could run. The base was a specific ni-cd battery pack and the number showed how long the motor could run on that capacity until the battery was depleted. For example: the le-mans240 could run 240 seconds until the battery pack was depleted All old kyosho motors had this kind of designation, not just one.

[@valkyrie9212]

CJ N The “s” stands for cells. Each cell is 3.7 volts so 2s means 7.4 volts, 3s means 11.1 volts, 4s is 14.8 volts and so on. As for motors 2s, 3s, 4s, 6s, and 8s capable motors are more standard. 5s and 7s would just be odd ratings but can definitely have a 5s or 7s build. Hope this helps.

[@ardz8279]

The S is for the connection "type" used to connect the batteries with each other and to the electrical circuit: either "Series" or "Parallel" connection. The 2s, 3s means that there's a "Series" connection: 2s, 3s, 4s, 5s, as in, 2 batteries connected to the circuit in "series," 3 batteries in "series," 4 batteries in "series," etc. A lithium battery rated to operate at a typical peak 3.7 volts (by itself) would be rated at 3.7v. So, what about 2 batteries in series? 3.7v x 2 = 7.4v. And three? 3.7v x 3 = 11.1v. It's 3.7 volts more with every multiple. YT is dabom to learn about Series/Parallel circuits.

[@RCJuice]

Most 540/36 motors come with 3mm screws, and most 40/42mm motors come with both 3mm and 4mm screw holes to give you the option. The spacing is the same between both motors, so if you have the physical clearance around it then you can usually bolt an 1/8 motor on a mount designed for 540/36mm motors. In some applications you may need to add some spacers under the mount to get the clearance between the motor can and the chassis plate.

[@ardz8279]

Can you explain the difference between "Internal stator" vs. "External stator" brushless motors, please.

[@philthycoder]

This difference is simple: Think of the stator as the part of the motor that doesn't move. Therefore, an external stator is what you see in all of the above examples, where the casing contains the windings and the central rotor is the moving part. An internal stator has the stationary windings in the center, and magnet-bearing rotor sits around that stator and drives the shaft. internal stator motors can either have an additional shroud around the "front" of the motor which conceals the moving rotor, or the rotor can actually just be the front housing, and the housing moves when the motor is running (think quadcopter motors)

[@RCJuice]

In general, motor shaft length is fixed on a motor and there are not options, there are some motors with options for a shaft diameter but not length. The know if the motor will fit you'd need to measure from the motor mounting plate, and up to whatever is behind it that the motor could hit. You just need 70mm of clearance and if so, then it should fit.

When there is difference in the width is clear that more rpm its better a 5mm but with long I dont know.

[@RCJuice]

@@cesarguerra6039 As far as the shaft length itself, 15mm and 17mm length are both pretty common lengths. They are very close and usually, there is no problem on shaft length being too long, if anything sometimes they are too short. Some applications can require a longer length but again, in general this is not a concern. You can mount a pinion gear in either direction on the shaft as long as the grub screw makes full contact with the shaft. I would not worry about the 15/17 as far as a deciding factor on what motor to buy. For the shaft diameter, 5mm is generally better since it is stronger, but make sure you can get the pinion gear you need in a 5mm bore. Some smaller pinion gears are much harder to find in 5mm so just ensure you can get the pinion gear you need.

I bought a 3650 3600kv motor and upgraded my FTX Carnage with it. My question is what does the 3650 in front mean?

[@RCJuice]

36mm diameter, 50mm length.

Howsit, to anyone who can help me out here, I’m more of a nitro person so I’m new to the electric world, Iv got an old tomahawk bx 1/10 scale which I’m wanting to convert to brushless, Iv been eying up the 3674 motor as it’s the longest I can fit on the chassis but my issue is I’m not sure as to which esc to run or what batteries I’d be able to run on it, wanting a balanced build with mega power, I’m willing to throw money at it so I’d rather get some advice from people who know their stuff before I end up wasting money and buying stuff that isn’t compatible lol, any advice anyone could give me I’d greatly appreciate it 🙏🏼

[@RCJuice]

It really depends on the KV you select and the application, most 1/10 scale is going to end up with either 2S or 3S. Since it's a larger 1/10 motor most likely 3S, but check out this video for some great info on KV/Voltage/Temps: kzbin.info/www/bejne/hGmWlZasmKaMqNU

@@RCJuice Thankyou for the reply! I appreciate the info!! Iv been recommended a 4068 and a 3660 motor what you’re thoughts on them?

[@RCJuice]

@@chadrautenbach574 What is the application? A 4068 is an 1/8 sized motor, but plenty of 1/10 cars will accept them. The only issue is the KV's are generally lower because most 1/8 rigs run 4S and up so on 2S or 3S you may not be happy with the top speed.

[@chadrautenbach574]

@@RCJuice Iv given up with that build man, old chassis and parts are hard to find for it, I was wanting to convert the tomahawk bx buggy 1/10, Iv just brought a kraton 6s to get me going and honestly what a machine

Look at Tamiya for source is my guess.

Castle and spektrum sizes are still a mystery js

[@RCJuice]

Yes, they are....

[@publicprofilename4273]

Do you think the reason the finned motors will have a true outside diameter measurement, for the purposes of fitment for custom builds? Maybe not so much for nefarious purposes. Of course you're probably right, cause capitalism.... But if I'm trying to make positive assumptions, I would figure that they're just trying to be helpful by reminding you about the extra couple millimeters to consider when motor shopping for you're custom rig build.

[@RCJuice]

It is a true outside diameter measurement, so it's good info to have when mounting space is tight. As is with many custom applications.

Lol my first rc car has a 3670 bruhsless motor and my second a 56113💀💀💀

He could compare rocks (there all the same ju some of them look like this and some look like that I don't really matter just rocks 😂

[@Mike_Greene]

my man keeps saying things like ALL which is not true. ALL 1:10 cars dont run with 36 mm motors and idk why this guy keeps saying things like that. Makes him sound like he dont know what he is talking about or is out of touch

[@AdoptedYooper]

I think I’m even more confused after watching this video 😣

[@paulsoto4040]

540

[@TheBabyskywalker]

Didn’t mention the power once!!!! I’m more after confused than I was prior to watching

[@bobgeldoff9413]

basically cos ive modified it to be higher and bigger wheels its more a 1/5 th now.in fact i think it looks bigger then some 1/5th scale cars.

[@jacktheripper-hp9tx]

what does the 5 mean

[@troyrichards2914]

The last motor what's the max size battery could you run? 12s ? 16s ? 21s ?
