What does 'digital' motor mean? I still don't know. Judging from the control waveform, Dyson doesn't either. We'll look at the Dyson motor from the inside out. We'll also do some test firing of the control board and motor on the bench and use our trusty Rigol to see what the motor controller is doing.

Agreed
Keep them in business for the next 30 years
Robert Emerson theres a very fine line
There's an AvE bumblefuck dictionary somewhere on the interwebs.
Dyson Vacuum next, I want you to investigate their bullshit with their suction technology
JACK SPARROW magic
JACK SPARROW yessss!
my dyson works pretty well but the materials are pretty junky, really wobbly plastic
My Dyson vacuum is 5 years old sucking up dog hair and it still works just as good as when I bought it
cyclone dust collection works great. look into cyclone dust collection for wood working shops, collection bins fill up but filters stay clean MUCH longer than a simple suction/filtration system. You can even add cyclone collection to existing filtration systems for woodworking. Works amazing for router and tablesaw work.
The 1 volt out is probably because it's designed to spin at 100krpm and you're giving it 300...
frollard That is a perfect explanation. The generated back emf is proportional to the rate at which the magnetic flux changes in the loop times the number of loops (turns) of wire.
So if your coil generated moderate -voltage at low RPM, you would need a ridiculously high voltage to drive-in at high rpm
the stepper motor has a very high wind count, and usually only run on 12 or 24V, high rpm require very low turn counts for more power. its the same in rc motors.
well i mean. SRSLY HOW IS HE GONNA DO THAT XDDDDDD
Yeah.. european.. like their cars that run at a million RPM and sound like dremel drills. And they don't have any neodidleyum either ;-)
funny guy! buy a european v8. low rpm!

Great and informative , people need to chill out and let the man be and express him self in any way he feels he wants to , people focusing on his accent changes and giving advice on how they want to hear it, that's not good , if you kill people's natural creativity you kill part of them , reversing what you actual want to achieve , open mindedness is the only way new information can be passed and received . Let it be . Keep up the good work .
Hey AvE love the combo of brains and bullshit, just not sure of the ratio.

in this vid he uses more German then in the vid with, the 5 inch Metabo "Winkelschleifer" ;)
i was gonna suggest AveAussie also but i think he's already bastardized English quite nicely haha
Basterdized Lol
The low emf does NOT mean it is not a brushless DC motor. The emf is more or less proportional to the RPM and must be compatible with whatever voltage the motor will be supplied with when running. That particular motor is meant to run at tens of thousands of RPM while you are cranking it at probably one or two thousand RPM so I would not expect it to generate more than one volt.
If you look at the type of motors used in RC airplanes, drones and such they have a 'KV' rating which specifies the RPM achievable per volt. These can vary from about 500 to 20,000 typically. At KV 20,000 motor may be rated at 80,000 RPM running on a power supply of 4 volts. Such a motor would typically be in a micro drone with a single cell LiIon battery.
More typical for a medium sized drone would be a KV=900 motor which would do, say 13,000 RPM at 11 volts. If turn the shaft of such a motor at 1000 RPM with an electric drill it will generate less than 1 volt p-p of EMF.
I think what you are seeing is just that.
Forgot to mention - same applies for a stepper motor, the difference is that a stepper motor is designed to work at very low RPM maintaining a high torque. Consequently even turning it slowly will generate a high voltage.
Lister Dave. Forgot to mention fack off!

Lister Dave is spot on though.

100w in that size isn't too surprising considering how much air they've got going through it.
I wonder if the failure to chooch in the vice might be because it's seeing the revs rise too quickly due to lack of air resistance from the housing.
i agree. the little electric brushless motor in my RC car is 1.6kW and that thing fits in the palm of your hand. i thought it would have more power.
1.6kw, wow that's one hell of a motor to fit in the palm of your hand. Strong forced air cooling?
Kalvinjj nope. just gets cooled down by air flowing past it. The car goes 120kph so there is plenty of airflow.
It's about 100W motor you plank! The other 1500 W is power consumption of the heating element.
You don't seem to be so good at reading... we ARE talking about the 100w only on the motor, and the 1.6 kW one is another story
A V2 rocket joke? This is the joke for me, this is why I'm here.
I spend quite a bit of my time in bed watching videos on UA-cam. A buddy of mine showed me your videos a few weeks back and I gotta say... You are definitely one of the most educational and informative creators on UA-cam. You are also one of the most entertaining. Thank you for every video you have posted.
I've heard other folks on here mention AvE, but it took me months to finally watch an AvE video. I've been missing out! Might have to adopt Neodydlium!

It's called a 'switched reluctance' motor. They're very cool, but not alien techology. They create a very fast rotating magnetic field within the rotor using the external coils. The rotor contains a special arangement of magnetically 'soft' and 'hard' (typically ferrite and transformer iron) materials that gets dragged around due to magnetic induction. This sets up eddy currents within the rotor which act like magnetic gear teeth. It is this gearing effect that allows the motors to reach such extermely high speeds.
The fan is taken from the design of small turbofan jet engines, which been the subject of incredibly rigourous research because of their uses in transportation, energy comversion and war. Also amazing, but well researched.
thank you mate. I just wander if it really runs continuously at 110k rpm? is it power effective? or power hungry. we don't use them in electrical drones?
Alexander Rice Induction of eddy currents in the rotor is negligible and has no effects on the working principle of the motor. Also there is no rotating magnetic field like in AC machines. Nobody who research on SRMs call it like that.
For a coil gun, you want a fast projectile, which suggests not only that is reluctance required, but also people have been doing it wrong.
definitely alien ... from planet ork
But SRM should have teeth on rotor as well. But that does not seem so from the video, its just a smooth cylindrical rotor.
The waveform is Class D mode B (pulses both high and low, thus having a "common mode" component). And I'm sure they are NdFeB magnets... The magnets are unplated, but passivated. Hobby motors use similar magnets with a similar surface treatment. The reason the back EMF voltage was low is because the number of turns on the coil is made low, to keep motor inductance low, to work well with the 30kHz switching waveform. What's so special about the motor is that there are not multiple "phases" as would commonly be the case with a typical brushless DC motor (for example 3 phases). Here there is only a single phase. The motor is started by the torque supplied by the coils, but pulling (initially) against the strong cogging torque.
Lol pangolin over here, this is not even in your bussiness direction :')
I was going to say it was a class D amp. I've read about this but never seen the actual wave forms. 100% awesome!
Hello Mr.Spock, how are things on Vulcan?
What ensures it starts in the proper direction?
blargg,
DC motor... I would think polarity.

Did dyson take the same thing as their "silent" room fans and use it in this hair dryer? Would be really cool if you could emulate that 30khtz wave and get the motor screaming again.
Saw (& heard) one of the early desk fans in use - to me it sounded like more of a resonance thing, more like spooling up a jet engine rather than the whistle of a motor controller.
I laughed; I learned. This is what youtube is for.

'Reluctance motor' sounds like one of your made-up terms!
en.wikipedia.org/wiki/Reluctance_motor
Wikipedia on the other hand, is made-up knowledge =)
Technically, all knowledge is made-up
No, actual knowledge is based on observation, experimentation and repeatability.
Because Wikipedia is unreliable at it's core. Granted, in many areas the "control of the masses" is sufficient to moderate and weed out malicious edits. But in many cases it's not. As it's an open platform, and anyone can edit it, no information is guaranteed to be correct or even relevant, even if it looks like it has decent references.
But yes, it can often be a good starting point, and to double check stuff that "you know", i.e. know well enough to know if the information is clearly falsified.

It dies, son!

Reluctance motors are composed purly of soft magnetic materials resulting in no cogging when the excitation windings are unpowered. For very high speed brushless motors you need both a high excitation voltage and a low stator inductance. This low inductance can be achieved by a low winding number. This will explain the small induced voltage when you turn it at low speed.
+Capo Agreed. From a quick bit of Googling it does indeed seem to be a permanent magnet motor as expected.
no idea what reluctance motors are and such. Do know in radio control inrunner motors there are 2 types of stators. Slotless and slotted. Slotted uses some kind of ferrous material (usually sintered and laminated) in the windings which creates the cogging when turning by hand. Slottless doesn't have any ferrous material in the stator and spins smoothly by hand. For rc applications the smaller higher kv motors intended for higher rpm generally have slotless stators while larger higher torque motors generally have slotted stators.
After typing this I reread your comment and better understand it. Now realizing I'm basically explaining the first part of your comment but still feel its relevant and not wanting to delte
hey AvE hook that to one of your power rectifiers and crank it up till it lets out the blue smoke
IT'S ALL RIGHT THERE SHEEPLE! WAKE UP!
LOL great laugh this morning.
WOULDN'T THE ABSENCE OF BRUSHES PROVE IT'S A BRUSHLESS MOTOR
No need to shout;) but you’re right. This is a brushless DC motor designer at high speeds (rpm) at low voltages.
The stepper is designed to have high torque at low voltages so it won’t ‘loose’ (skip) steps.
What's the saying... Less is more? So I guess the absence of brushes is technically the most brushes one could have.
Elegant profanity and I was entertained! Nice one!!

I'm in a low class college with no electricity and I understand what *you're* talking about.
The way that motor is designed reminds me of the sensored brushless motor in my RC truck. Runs at 12.6V pulling 20A. Size of a D-Cell. It's mental.
most 3.5t 540 sized brushless motors are rated at a bit under 700w!
Yeah I havea Trackstar 13.5T 540 3150kv that is quite powerful. Designed for 2S but it runs 3S no problem.
My friends racing RC car has a sensorless brushless motor running at 16.8Vand pulls 100A continuous or 210A burst current, it runs at like 55K RPM and makes like 4 HP and its about the size of a D-Battery too.
Back when motors where Brushed a 36mm can (540) is what you would find in a 14volt DeWalt drill and a 40mm can like a Castle 2200kv (775) is what you would find in a 18volt DeWalt drill. With these new Brushless motors I don't know if there is a standard can size for power tools.
That sounds about right. The most I've seen on a Castle log from a 40x96mm brushless motor was 14hp running 8s
AvE has been identified. neodiddlyum. AvE is ned flanders.
you should make a t shirt that says "it's all just 1s & 0s" and have a smoking power tool in the background.
What you talking about Willis?
I've learn't pretty much everything I know from you, sir. Thanks for letting me hang out with ya and have a few beers and laughs.
You are wrong! This is a brushless DC with a neodymium magnet core! Speed is monitored by a Hall sensor and controlled by a 8-bit microcontroller switching with a h bridge of mosfets.
can you back this up, he took it apart lol
Did you even watch the video? That's not neodymium.
Seems lika a weak neadymium then.....
High speed requires a weak magnet, not a strong one. Also, neodymium is not rugged enough. Protective chrome coatings and quality control would be way too much hassle.
Nicholas R.M. Technically speaking, the hall sensors are used for position, not speed. That is how the commutation is done in a sensored brushless DC motor. If that is the case, it would not function properly when the motor is separated from the all sensors and the hall senses are often on the PCBoard.
AvR thanks that this is a sensor less brushless DC motor in which case there are no hall sensors and no optical sensors at set up for position sensing. The position sensing must be inferred by current or back EMF in the coils.
Believe me when I say I've never seen anything of yours nor do I know how this got on my homepage. But I like it.
Thanks for the free edumakation! :D

So the Dyson advert machine is 100% all wank, who would have thought.
Shocking, innit?
The adwert IS all wank, as always. BUT this was a seriously fancy machine with more expensive and fancy parts than its $20 counterpart.
But have you ever owned any dyson products?
I have got 2 vacuums, despite the marketing, they just work, and work really really well. Blows anything else out of the market and thats what dyson does.
My corded vac, 12 years old or just about, spent a total of $15AUD on it in that time, I lost my favorite tool for it, so just called a number and had one posted easy as pie. And I dont even baby it, Vacuume plaster dust, saw dust, sand, Hell even broken glass from a smashed car tailgate window. Now I have one of their cordless items, i dont even use the plug in, Sent it to my brothers house when their shitbox broke.
Expensive yes, but the proof is in the long term cost.
Yeah but it dries the hair well 🤷🏼♀️ cuts down my getting ready time from 90 to 45 mins
Not to mention 500 dollars spread across 100,000 people who almost definitely never buy this hair dryer, or take it apart..
We should all give him the half a cent each he needs to buy another $500 take-apart-toy/dissection subject.
or if a tenth of a percent just became patreons...
keep your vick in a dyse(-on)
Oh man, after I stopped laughing and learning, I subbed you, brilliant! 👍😎
New favorite word... Bumblefuckery.
Nice math at the end of the video. Enjoy your video not just for the edumacation. But for the funny bits too. Learning can expensive if you do it right, like at university.
There are plenty of brushless motors for RC planes and especially multicopters that have very low back emf constants, like 300-500 rpm/volt. So unless your drill can do 1000+ rpm it's not that surprising to see only 1-2v out. It's also not uncommon to see small motors like that (150-200 grams) rated for 300+ watts (maybe optimistic, but they too have exposed windings with a lot of surface area and air moving directly across them)
That said, I don't see anything on the board that makes it obvious what kind of motor or drive topology they're using. Especially confusing to see only two power transistors and two wires going out to the motor. Is the blue box a film cap? How is it connected - in parallel with the electrolytics or something else? Does the motor have any cap out there with it (like a single phase AC motor)?
is there an AvE drinking game? Its got what drunk nerds crave.
apcolleen Brawndo!
apcolleen Every time he says "Fack" or "doodly-doo"...
apcolleen check for his "drinko" vidjayo.
Loving the combination of invented words, technical knowledge and just general give-no-fuckery it's a refreshing change keep up the good work sir!
seems like you never saw water pump on washing machine. Basically same design just dyson wanted higher speeds so instead using 50 (or 60)Hz from net they added their own controller to adjust frequency and by that adjust speed..

neodiddlium magnets
Every time. I learn something new, and I get a good laugh. Thanks man.
Some reluctance motors have magnets embedded in the rota to assist channel the magnetic lines of force through corridors eg the Tesla motor
As a magnet specialist, I can confirm the magnet on the rotor is a neodymium multipole ring magnet.
AvE, Shop Tour?

I know what neodymium is. It was the humorous mispronunciation that I was pointing out.

the newest dyson motor patent 20170170697 states: ' The magnet ( ex: that is mounted on the rotor ) is a bonded permanent magnet of the sort typically used in permanent magnet brushless motors, and in the example shown the magnet is a four-pole permanent magnet.'
Reading the patent it strikes that the main focus is in creating components that are in essential aspects optimized to lower friction, weight, increase airflow. The c-core stator is a unique work of art and the true heart of this optimized motor.
Actually, the low voltage is due to the motor being designed to run at high rpm. It's engineered to hit 110k rpm at its operative voltage, therefore you'd have to reach that rpm to get the voltage out of it. Your drill simply doesn't have the rpm output to get the voltage up. Also the voltage measurement could be off by measuring across two phases only give 66.7% of the voltage. Your stepper motor is engineered to operate at very low speeds, which is why you can get voltage from it by spinning it with your hand.
Bouta go verify that,but not suprised if homie didn't glance at the engineering documentation (he only reads when he's on toilet)
I wanna believe all the eng resources at Dyson they'd have something very unique. A 110Krpm motor like this is super cool!
Thanks for the detail.
I wished someone did something like this for the V10 or V11 motors.
90% of the time i cant understand you 😂
The "Veetavagamix".... HAHAHAHAHAHA
Does the Dyson patents not describe the construction and operation of the motor?
Probably but where’s the fun in that.
"JFM!", "Doctoral Dissertation", "Palestine", "Sheple" I love this guy!! lol
I wondered myself when I saw the claims of inventing a new motor.
I have to admit that I'd not come across a two coil brushless DC motor before this.
While I admit that the breadth of my motor experience is not that wide, all the ones that I had encountered had been 3 pole motors, the most common using, at any one time, 2 coils for driving and the undriven coil for sensing.
This difference was enough for me to concede, for the time being, that their claim of invention was not altogether nonsense.
Regarding dicks in vices. Do you have any special methods or tools for non-destructive extraction ??
