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?

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

@beachboardfan9544 2 года назад

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...

@remkojerphanion4686 2 года назад

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

Thank you!

@sputnikwood Год назад

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

Thank you for teaching us something new

@RCexplained 2 года назад

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

Great info.👍🤙

Thanks 👍

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. 🤔😁

Right on!

@z1mon119 Год назад

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

@open-ats9990 2 года назад

cool never thought about that ;)

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

@chosebines51 2 года назад

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

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?

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

@RCexplained 2 года назад

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

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

Try this ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-JD1gplvhGrc.html

@therctutor8100 2 года назад

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

@tedsimington7654 Год назад

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

@RCexplained Год назад

Yes

@metroduplic8r5 Год назад

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

@ubreakitirepairit3569 2 года назад

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 2 года назад

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.
