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

Ғылым және технология

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

    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...

    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?

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

    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?

    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.

    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

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