Brushless Motors explained in layman's terms (by a Star Wars dork) - New Dewalt Milwaukee Makita

Let's peel the skin back on a brand spankin' new Dewalt 20V XR brushless impact to learn, in layman's terms, how new brushless technology works. Explanations on how Pulse Width Modulation allows digital electronics to output analog voltages, what AC frequency the tools run on and some star wars tomfoolery.

Good god ive watching your videos for almost a decade now! I remember watching this when it came out.

Thank you so much for that PhD line - I too have a post hole digger in the garage...

i laughed so hard at your comment, i thought he was serious until you said that.

[@millwright15]

Thanks, KZbin algorithm. You knew I needed to see the AvE video.

[@VeganHippy70]

I think this is one of your best videos - tear down with electronics tutorial. Keep up the great work.

[@aleksmukha7787]

Just wanted to say thank you for posting a video made by someone competent about what they are making a video on. Trying to look at other videos on brushless motors and they're childs play in comparison.

[@joshuacarey9367]

My favorite show. I listened to you before I go to bed to wind down after working long hours building shit lol. Its calming to know how a tool will fare under the shiny parts. Thank you !

[@TheSqoou]

Look up "aspect ratio" on your Confuser. You've uploaded a 16 by 9 widescreen video in the 4 by 3 standard format. That's why there are black areas around the entire video.

[@TheSqoou]

***** Now that everything's gone digital, public access TV is free for the pickins. Radio too.

[@JeremyPeters]

The Sqoou You should really know what you are talking about before posting things...if this was exported at a 4:3 aspect ratio, the bars would only be on the right and left, not top and bottom. What is more likely the case is exporting at less that 1920x1080 pixels but it is still 16:9.

[@JeremyPeters]

The Sqoou You can have a video that's half the size of your thumbnail and still be 16:9. Size has nothing to do with it, it's the relationship between the length of the top and that of the side that determines aspect ratio.

[@TheSqoou]

Jeremy Peters Oh I see. I've seen it happen also from recording in one editing in another then uploading in one again. Thanks for the correction though. NEEEEERDDDD !!! ... lol

[@brianbowman5402]

I've been watching and enjoying you for a few of weeks. I like your style and we all know you are sharp with a sense of humor. So, hearing you had a Ph.D. kind of fits. Keep pushing the trades, we need them! Anyway, why are you so into the brushes? Yes, its were the electrons meet the road, but are there any performance impacts. Maybe a demo on the same motor with different brushes?

[@drdrums1]

Unless I missed it, your video title is misleading - you don't go into how brushless motors work here. Rather, you're explaining PWM (and doing it quite well!!!). PWM is applicable equally to brushed motors (as you have shown in other videos). Brushless certainly uses PWM for speed control, but the fundamental difference is brushless motors include electronic commutation via FET (or some other switching transistor type), while brushed motors, true to their name, use brushes for mechanical commutation. But you probably knew that.

[@DanielPhillips1977]

[@TokayGekko]

Hey Dr. AvE. Thanks for all the great videos you've made. I've learned a lot of machining stuff (I'm one of those electrocity oriented dudes) from your videos, as well as gotten a lot of laughs. So I though I should teach you something as a thanks. 0v is not the same thing as no voltage. If you wrap your head around it I guess you'll understand why. A voltage is always in relation to another electrical potential/voltage. And especially in confuser circuits its important that a '0' is connected to ground/0v and not just "hanging in the air", if you get what I mean.

[@ZJASPAIR12G]

[@renejacques8288]

I'm trying to fix my dcf899 that does nothing when I pull the trigger. I wanna test if power gets to the motor while pulling the trigger, but my friend warned me about backfeeding. Do you have any suggestion please?

Make a video tearing apart a drill from amazon and the same exact drill from the depot ! I have a strong feeling there are some major differences.

That's far-fetched, Godly explanations? I would say great at best.

[@edwardbadlands8621]

Gotta love AC/DC rock on AvE

[@adrianrodriguez6046]

So, because we’re converting to AC, it’s safe to assume the 14 volts he read is because: Veffective = Vmax/sqrt(2) = 20/1.41 = 14.18V

my freightliner trucks heater motor must be brushless the am radio is being drowned out by this same sound . any idea how I can cancel it out?

[@MoeBabaloosh]

My brother's old Toyota did the same thing, and when he accelerated, you could hear the pitch go higher through the speakers. He took it to a friend's shop and they installed something called a "ground loop isolator" on the radio. Not sure how it works or how to install it, but it worked. Hope that helps.

+AvE Whats your PhD in? I'm materials science coming from a mech e undergrad. I like your parts about "reckoning", I try to teach my students to think about their answers in a similar fashion. They often don't anyways. For instance, I'll craft a problem dealing with diffusion that expects an answer of tens of hours--then I'll often times see answers that exceed the age of the universe, or are so fast that a photon doesn't have time to transverse the entire distance of a proton.

[@talamacus73]

Piled Higher and Deeper.

[@mrrodgersphysics]

This guy is very knowledgeable (and pretty funny) - but I think his explanation of PWM is off. My understanding is that the signal from a PWM pin is always at 100% of the operating voltage, but by modulating the with of the pulse, the microprocessor can vary the power available to the motor. The whole reason one needs PWM, as opposed to something simple like a rheostat, is that most motors simply won't work once the supply voltage drops below a certain value. So if you try to run an 18 volt motor at 10% power by putting 1.8 volts across it, it just won't turn at all. If you give it a full 18V, but only for 1 out of every 10 µs, it'll run, but only 1/10 as fast/powerfully. I think the display on the o-scope confirms my interpretation of PWM; the multi-meter is confused because it's in AC mode, but it's reading what is actually a digital signal. Again, this guy knows a stink-ton more than I do about materials and manufacturing, so I'm ready to be corrected - but I don't think I'm wrong.

[@zyxw12347]

+mrrodgersphysics Very close, but there are multiple measurements being taken. The multimeter was in VAC whilst across two of the three motor windings; the reason being, the MOSFETS that control the motor are outputting AC. That "brushless DC" motor is essentially a 3 phase motor with a permanent magnet armature!

[@keithjurena9319]

torque is a function of current..pwm for motor control is variable torque as 10% duty cycle is closer to 10% rated torque at stall than 10% of rated voltage. RC electric aircraft have used PWM for motor throttle for a while now. and with brushless and sensorless PM motors. pretty awesome to get 1Hp from a 4 ounce motor running 16 volts at 65 amps..

[@silvermediastudio]

+mrrodgersphysics Don't ruin it. haha

[@chadkrause6574]

Close on the PWM. There really are 2 types, the one your talking about (like what arduinos put out) and then there is the RC standard where it goes from 1ms to 2ms and 1.5ms is neutral and 2ms is full forward and 1ms is full backward. Then this repeats every 10-11ms

[@kickinbackinOC]

zyxw12347 Hey, buddy! Was just looking at some older and hilarious AVE videos, and came across your comment! So if it's a three phase motor, I guess it has three windings? Are the windings hooked up in delta format? How many leads come out of the motor? 3, or 6, or? The reason I'm interested, is I need a very small 3 phase motor with 6 leads, which is an even longer story!

[@padraics]

Young AvE, so serious!

[@ericluffy7970]

Make the three wires on the motor go: ++0--0 0--0++ -0++0- wherein the the 0 is important to nullify the 3x or 1. harmonic.

[@GBlunted]

Interesting how I didn't balk when the term, 'DaveCAD' was actually used in a sentence? I watch too much of you KZbin makers! Although this AvE guy I'm not as familiar with (will subscribe after I post this comment) probably because of my personal preference for electrical education and the more electricity oriented side of making things and stuff...but after a few videos I'd queued up and made it through, I'm subscribing to this guy for the jokes!
