BOLTR: Dyson V9 Motor. ALIEN TECHNOLOGY CONFIRMED?!

Official C**T Hair ruler: ► www.etsy.com/ca/listing/46420...
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.

You are definitely one of the most educational and informative creators on KZbin. You are also one of the most entertaining. Thank you for every video you have posted.

[@frollard]

The 1 volt out is probably because it's designed to spin at 100krpm and you're giving it 300...

[@davidsuzukiispolpot]

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

[@Flyingwigs]

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.

[@thelennipede9382]

[@djaydeved]

... FULL BRIDGE RECTIFIRE

[@listerdave1240]

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.

[@listerdave1240]

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.

Let it be . Keep up the good work .

[@alexanderrice5224]

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.

[@jjkosinski]

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?

[@nfsking2000]

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.

[@bansheedearg]

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.

[@Financialturmoilexplained]

definitely alien ... from planet ork

[@Debraj1978]

But SRM should have teeth on rotor as well. But that does not seem so from the video, its just a smooth cylindrical rotor.

[@PangolinSystems]

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.

[@natemorte]

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.

I didn’t understand half of what you did/said but I’m subscribed. So much fun.

[@RichardRParsons]

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.

[@Graham_Langley]

+Capo Agreed. From a quick bit of Googling it does indeed seem to be a permanent magnet motor as expected.

[@OverdrivenXR]

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

[@Sizukun1]

just a thought: the magnet must be working against the imposed field. this means F is proportional to V x B. to get some real horsepower, a crummy magnet could be compensated for by a humungous B field, which in this case may be the intent, i.e. to be pulsed at high rate and voltage. if you measure the horsepower, and input power, then compare the efficiency to a normal motor to see if the hi voltage approach in the B-field generator is worth the weight. second design intent may be that the horsepower per volume may be a novelty so that can also be compared. i would expect that the intent is a cheaper way to get enough horsepower in a smaller and lighter package.

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.

First time viewer. Happened upon this video after watching a top 10 "strange engine" video. I'm sure it has been said many times before but video was very informative and, more importantly, very entertaining. It's too bad i didn't have profs like you in College or i may have dove off into some form of engineering major. Anyway, very cool video and first couple min was enough to get my sub. Keep up the good work sir.

Can someone explain to me what that green exray paper thing is, it's really interesting.

[@discountoutdoorstore]

Its called magnetic viewing film...shows you the magnetic field lines. Handy for figuring out the configuration of the poles and such.

There is no green paper in this video, Steve. Discount, that film you're discussing doesn't answer Steve's question, because Steve asked about green paper, which there is none of here.

[@tomplum2751]

Yes it is. And Frank, 2π Radians is 6.28 (2.dp) which you've rounded up to 6.3c. That's the same as 2π.

This channel is pure therapy.

I still think that once the smoke escapes the unit is kaput. This was so enjoyable, brushed motors, brushless motors, reluctant motors all combined with alien technology. Just an amazing video. Thank You
