Measuring Kv of a BRUSHED Motor & What does that ring do?

Finally a Brushed Motor Video! Here we determine how to calculate Kv for a brushed motor. In fact it easier than figuring out the Kv value for a brushless motor! Then we spend some time on that ring found on many brushed motors. Is there a purpose to it?

When I was into R/C hobby motors and cars i never heard about the ring? Thats interesting! I always wanted to know how to measure KV on brushed motors and after 15 years now I know! Top tutorial so i subbed and liked 👍. Cheers from Australia 👍

[@RCexplained]

Thanks for the comment and sub!

[@beachboardfan9544]

Need to do a vid about that torque ring! Is it just shielding, is it redirecting the field, how does it do what it does? Seems pretty significant for some static object...

[@romper4444]

Wow man I TRULY LOVE your videos! You answer so many questions I've always had in my mind about all things RC

[@remkojerphanion4686]

I've always had my own ideas about "torque rings", but now I know for sure 😉 Cool video!

[@RCexplained]

Thank you!

[@sputnikwood]

I always thought it was just a ring so they can put the brand name on it. Thank you for this info!

[@carnivorecave]

I have jb welded magnets to the sides of motors...Increase the torque.

[@colin1992]

Thank you for teaching us something new

[@RCexplained]

Hey Colin, I hope I can continue to do so.

[@rcbustanut2057]

Awesome info, thanks for sharing 😎 👍
I still have several 12T traxxas motors kicking around after brushless conversions. I may have to experiment with this for the sake of engineering fun. 🤔😁

[@RCexplained]

Right on!

[@z1mon119]

how much kv did yours with and without the standard ring have?

[@madmaxximus1234]

Great info.👍🤙

[@RCexplained]

Thanks 👍

[@open-ats9990]

cool never thought about that ;)

[@haikalyusuf4058]

hey! I came across your 2 videos on BLDC motors as I’ve been having troubles with mine
I wanted to clarify if it’s possible for a spoilt motor controller to spoil a BLDC motor? As reference, I’m using these motor controllers from AliExpress on hoverboard wheels & I noticed using a working motor controller on this “spoilt” BLDC motor causes it to turn a bit at the start, before it makes a whirring sound
Used this exact same motor controller on the another BLDC motor & it can move fine
I’ve ran this “spoilt” BLDC motor through several motor controllers that were afterwards burnt so I’m not sure if the spoilt motor controllers could’ve indeed spoilt it
Is the “spoilt” BLDC motor really spoilt?

[@chosebines51]

The purpose of that ring is to hold the magnetic field closer. Result is probably better torque.

[@nolimitsmunson7475]

which video do I need to watch to get my drill to brushless motor reading info?

[@RCexplained]

[@tedsimington7654]

Can you run the R/C car with out the ring on it? Thanks for sharing👍

[@RCexplained]

Yes

[@fishtailfistscale8362]

So the song goes … if you like then you shoulda put a ring on it! Ha I get it now

[@RCexplained]

Oh, I heard this song before. Now I'm married.

[@owen8538]

Hi anyone know kv of the 14t gorgon

[@polishguywithhardtospellna8227]

9:26 "last question we... Javier"
😅😅😅

[@metroduplic8r5]

What happens if you put two of the rings on the motor?

[@therctutor8100]

I would imagine that the ring increases torque as its extra metal for the magnets to “stick” to.

[@ubreakitirepairit3569]

I think in the end you meant "unplug" your equipment so your batteries don't die. From what I understand, an ESC will still draw from the batteries even when turned off. True or False?

[@RCexplained]

I left the multimeter on last time I used it and the battery was dead. But, it most definitely is correct that an ESC will draw power from the batteries and its best to unplug the battery from the ESC.

[@MangoJim90]

👍👍🔥🌄🙌🤗

[@TheGuzo80]

I think it is a magnetic shield ..

[@Patrick3450]

The ring will increase the torque. The kv will be lower with the ring

[@ragsixracing]

Torque ring

[@ragsixracing]

Why not just put 1 volt thru the motor, then measure the rpm of motor shaft???

[@RCexplained]

This is not the standard and would lead to a different result.

[@did3d523]

kv on brushless is when motor is free.. if you connect to a brushed all is false . if you have tachometer juste take it on brushed direct

[@MrKuztumpainterz]

Heat sink

[@radiocontrolcardevelopment7329]

Some people use it to increase there euhm ... Oh wait no ....

[@romper4444]

Ok hang on... Kv= 1355/7.2v =188.19kv?
That can't be right? I'd guess that 775 motor is around 1700kv no?

[@koruj3264]

this ring is used to increase power by messing with magneses

[@elijahhansberry1558]

Torque ring

[@RCexplained]

yep
