Good gravy are there just so many motors out there. Like brushless DC motors which are absolutely cool in their own right! Therefore I just want to put up here that you should _definitely not_ go thinking that all motors work like this, because many don't! In fact, the universal motor? One of the reasons those are still so common despite their (relatively) shorter life is that they create *gobs* of starting torque on their own. An induction motor would be absolutely awful for something like a power tool with its poor starting torque, unless you went real fancy with a VFD and stuff. It's all about what's best for what purpose!
I love the idea behind brushless dc motors, it's so ridiculous that we can build the things at all. Take what's essentially a multi-phase ac motor, and then have solid-state electronics switch between the phases. Fancier ones can even do things like detect the rotor position by measuring the effects of the (typically permanent magnet) rotor on the winding fields, and apply torque to hold the rotor in place.
I don't know why I watch you but I do and I love it please keep doing what you're doing!!!
Brushless "DC" motors are just AC motors with DC compatible power circuitry.
It's all relativity's fault.
The correct term for an AC variable speed drive is an "Inverter Drive" Telemecanique call them Altivar but that's a trade name. Brushless DC motors are in reality AC motors which are not new at all it's just the miniature Inverter drives that they are more popular. But still will never have as much low speed Torque as a DC motor. With DC you can have Full Torque at Zero speed, it is possible with ac using full flux vectoring however they are very complex and require the motor to have an encoder.

TLDW: Initiating the spin requires more power than maintaining the rotation. This is why if you have a fan thats dying you can sometimes spin it by hand to get it started and it will run fine.

"It operates a lot like transformers but it is in fact a Decepticon" God I had to take a break after this one
The spooky part about this comment is I started reading it right when he said it 😂
When I was a child I had an old reel to reel tape recorder with that type of shaded pole induction motor, where the manufacturer has got clever and put secondary windings on it to drive the electronics so it was a transformer as well

underrated comment
I have an oldish fan (maybe 30 years old, so looks fairly modern compared to the real antique fans) with push button speed control. It very often fails to start on low. I discovered on my own that if I put it on high first, then switch it to low, it does fine, so that's what I normally do. I did assume the higher power was helping it get started, but I'm very glad (because I'm also a big nerd) to know the details of what is going on. As for why this particular fan can't start on low, I'm guessing it's higher bearing friction due to its age since it used to be able to start on low just fine.
It probably needs a clean up and regressing or fresh oil on felt(usually around the bush).. It depends on the design as to which it is. Most modern fans in Australia since the 90's, a light layer of grease does the trick after a dismantle and clean. (Don't robes the bushes unless they're designed to be easily removed, just clean them through!).
My Cold Spot fan sold in Sears in 1950 has no speed control and no switch. Just plug it in and it runs. Bought it at an antique shop years ago. Before using it I took the motor apart and did a thorough cleaning of the rotor & stator. Cleaned the air vent slots and the two bushings. Put it back together and used # 30 oil to lube the bushings. I recommend that you do the same to your antique fan. It will make your fan happy. If I lived in the same town as you I would do the work for free if you didn’t feel comfortable tackling the job yourself. I can’t afford to be a Patreon so it would be my way of giving back.

TC, thank you so much for always having such good captions/subtitles on your videos. I hope you never forget how appreciated they are and how many people they are immensely useful to. It's hard to find effortful captions these days and content creators who are conscious of this need and feature on their videos and who consistently put in the time to making them well-written for their viewers. I am very grateful 🙏🏻
This is the third channel I know of that actively does that. I personally don't need the captions and rarely if ever use them, but I do appreciate them for those who do. I always think significantly higher of channels that do, it's a small but extremely helpful thing for a lot of people
I agree sometimes I like watching g his stuff while listening to music. Plus he writes scripts and uses a teleprompter which I'm sure makes it a bit easier for him to do this.

As an avid fan collector, I’m thoroughly impressed with this video. The explanations are FANtastic. The off-high-medium-low sequence is the most commonly found on fans with rotary switches. But there’s plenty of fans with the increasing speed sequence. Also, that’s one fine 1930s Robbins & Myers 1304 table fan you got there :)

Decepticons are transformers
@@MrKYT-gb8gs Finally, an educated person
I always thought it was a safety thing, since you're more likely to shut the thing off when it's going faster.
I figured it was for kids, since they like to do things like turn knobs, and they usually like to turn them to one extreme or the other. Instead of turning it to a more dangerous high speed, they would turn it to either off or low.
I guessed the reason correctly, because my cheap fan stall a lot, I need to turn it with hand before it can turn on its own, just like old propeller plane, so I guessed it has something to do with torque and friction
Yeah id always thought "oh like stoves that makes sense" but I never actually thought about it
@@ImAlwaysHere1 what kind of logic is that dude?
@@Scumful The logic is that if a child turned the knob, it is likely they would turn the fan off or to a lower speed. The reason that might be important is that children also like to stick their fingers in fans. If the fan is off, the child would not get injured. If it is on low, the child's fingers are likely to get less damage, or possibly stop the slow moving fan blades and receive no damage. I thought the logic was pretty clear.

Stalling is still a thing on PC fans. When you bypass auto fan controls on modern motherboards (to allow fan stop) you need to measure manually how much duty cycle you need to start the fan again reliably. I have 3 exact fans models but each on of them starts at different %, so I end up taking the highest value. The reason for this is to activate the fans quietly when you need them, scale them to the desired temperature.

Thanks from a long time fan, it feels like this video was made for me. I used an old fan from my grandparents which had a button to push down to select a speed and if you started at a low speed it sometimes stalled and you could see it sort of arcing or something to try to get it to go and it felt quite unsafe so I stopped using it. This video helps me understand why it behaved that way. They don't build 'em like they used to!
I've been curious about this forever. I understand why old some dysfunctional fans I've had to deal with wouldn't get started until I physically spun the blades myself to get it started. Very interesting.
Before watching the video, I really thought the main reason for _1-2-3-OFF_ was to save the fan from inadvertently being left on. My reasoning was that if you're in a hurry (or just inattentive) and turn the knob towards 'OFF' before rushing out of the room, you'll immediately be aware that you didn't turn it all the way if it's now on '3' (or 'max'). But if '1' were next to 'OFF', you might think the fan's slowing down means it's about to stop as you walk away, when it'll actually be wasting electricity for all the hours you're away.
You have a point.
Have you noticed that it's like that on gas stoves? I still think the reason is safety, so you don't accidentally leave it on the tiniest flame and not notice.
@@sindicta5757 Indeed 👍
I never thought that before, but thats a good point and some solid thinking! As for gas stoves that do the same thing, it could be for safety, but now after watching the video I think it's so the flame has enough gas to ignite in the first place from being set to the "high" setting.

If the fan wobbles too much when on high it's unbalanced. Much like balancing the wheels on a car after installing tires, there's weights that can be applied to fix this.
@@user-ez9id7td4b I don't have enough fans installed to raise the ceiling **ba-dum-tiss**
I love the useless setting! It's designed to cycle the air around without a lot of air flow. My fan is on the 1 setting all winter to help circulate the hot air from the ceiling to the floor. Hot air rises so all the heat in your house just sits up at the ceiling and your floors stay cold. A ceiling fan will push that hot air down or pull that cold air up and helps keep the room more equally heated

Side note, I'd love to see a "Our US Electrical System is Weird- here's why" video.
Ah, but that's a story for another time
*starts new KZhead channel* still not enough to cover this topic
Great Idea. TBH "why is Something in the US Stupid" could be a whole series!
Mantis 04 pbs ?
If you think it is weird now go back in time 50-90 years when there were pockets of DC, 25Hz and 50Hz grid in the country...Then consider the time before outlets were standardized where each room would only have a lamp or in some cases a lamp and a power receptacle that consisted of a lamp socket near the baseboard of the room with a little door to cover it when your electric fan or other device wasn't connected...
I've been looking for a channel like this my whole life not sure how I am just finding it. Keep up the good work !
I've noticed very recent fan designs seem to no longer do this, but thank you. I've wondered this for years.
This is the first time ive heard someone be smart while referring to a rotor as a “spinning thingy”
@Ken Hudson to this day we have to do something like that. I'm sure you've used a pull start lawnmower or weed whacker at some point, right? Just like the old wind up cars and biplanes, you're pulling a cord wrapped around the motor to get it spinning.
@Ken Hudson I think Charles Kettering invented the self-starter for cars and made a bundle of money. In the teens or 20s I think.
@@AndyZach Kettering made the first practical electric starter motor for cars in 1911 and Cadillac used them on their 1912 models. He was a cofounder of Dayton Engineering Laboratories Company, abbreviated as DELCO (later bought by General Motors and merged with their spark plug division AC Ignitions to become ACDELCO). Kettering was a very prolific designer, and had near 200 patents in everything from electrical designs to paint to diesel engines to cruise missiles (in 1918) .
"This here is my biggest fan" _sad viewer noises_
I cackled

Well done. I thought you explained the simplified electrical intricacies very well. You have gained a new fan.
I have a fridge fan that stoped turning last week. I replaced with a new one, but still didn't knew why the old one stopped working. Now your video is giving me a clue.
"They look a lot like Transformers, but they're actually Decepticons." Well done XD
Lol 😁😂
Decepticons are transformers!!!! AHHHHHHHHH
"They look a lot like Transformers but are actually Go-Bots" would have made more sense.
Watch this
@@jamesdlin7 Pretty sure he's playing on the word "Deceptive"
I literally could not care less about this, that being said, I watched the entire video.
I got lost about 3 minutes in. After that it was just me listening to him ramble and show some fancy diagrams. I really just don't get this stuff, and most likely never will 😅
Well i actually hate this since fans are really irritating, j mean when you turn it on and its already its highest speed your like,welp....that was it,thats the max,see?no satisfaction
Well maybe you don't, but I'm a fan.
same -_-
Welcome to Technology Connections, get used to it
I actually discovered a few of these concepts on my own, by accident, without realizing it. I sleep with a small fan blowing on my face, and when my last one started stalling out, (after running for several hours a day for 8+ years) I figured out that switching it to high would get it going and then change it back to low or medium.
I had wondered about this ever since I first saw an induction motor in physics class at high school and when I asked about how they wouldn't start I was just given a nothing answer, I had completely forgotten about it. As I learned more I had just assumed that they would use a capacitor to create a phase delay, and then never really thought about it again. I never knew about shade poles, such an ingenious if not MacGyver-esque solution. Great video man!
"This looks a lot like transformers but are indeed decepticons" I had to pause the video to laugh
I guffawed
And I had to stop to write an angry " um well actually!" Comment about decepticons still being transformers.
In old reel to reel tape recorders the motors WERE literary transformers. 2 in 1.
I just laughed while watching. But you do you.
"Fans: it's what's for dinner!" Mmm... dusty.
😂😂😂😂 they do collect dust
Can someone explain me this joke? I’m not a native speaker.
Old 90s joke. BEEF, ITS WHATS FOR DINNER
@@AttilaTheHun333333 "Beef. It's What's for Dinner" is an American advertising slogan and campaign aimed to promote the benefits of incorporating beef into a healthy diet. . It's just a silly reference.
@@Lethgar_Smith thanks for the explanation. I'm not an american. That's why i don't understand the reference
Nice concept and episode -- it got me to take a double-take on some our 3 still in use Westinghouse fans (more than 100 years old) - and THEY start at low. They are a nice complement to our 99 year old house....and push massive amounts of air!
I watched this video long ago and it all makes sense. Just recently I remembered I have a box fan from the 1970s that has the settings OFF, HIGH, LOW, OFF. It's worked great over the years with just minor oiling. It's motor seems rather large. Just wanted to offer that counterexample.
"We are talking about Flemming's rules and Lenz's Law when you are older" He's technically correct !
Because time passes
The best *kind* of correct!
@SHAHMI ISKANDAR BIN SHAMSUL - he'll talk about it in the future. in the future you will be older.
@@Archgeek0 Awwww. I wanted to say that.
I'm glad to see Technology Connections isn't too big to dedicate an entire video to it's fans.
Get out, but first here is a high five
glad* its*
I work for a motor/VFD manufacturer and I appreciate the first part of the video. Well explained even if you say you oversimplified it
I can't sleep without a fan blowing full blast at my face! I'm glad the high setting is right next to off because I never use the medium and low settings. Fun fact: in South Korea, a lot of people are superstitious about fans and somehow think that fans blowing at night is dangerous because they think the fans steal your breath, lol.
6:09 “something like a fan which could be running for DAYS at a time...” Laughs nervously at the fan in my room that I turned on and forgot about years ago.
1000+ days is still "days." Also, don't turn that fan off unless you want to buy a new one. A fan that's been running for that long will very often die if you turn it off and try to restart it. As we said of hard drives in I.T., "it's like patients in an old folks' home, you put them down to sleep and some just don't wake up."
That's a really long time!
i am high class cause i turn mine off every 4 years to clean it;)
@@Bacteriophagebs And 1000 days is 8.64e+7 seconds, which is still "seconds" but that's not how we communicate timeframes, sir.
Wtf that fan is probably the dustiest dirtiest garbage ass fan
my fan goes from off, low, medium, high sorry ladies i'm already single
Yuh I got 0, 1, 2, 3
@Briny what the hell kinda fan do you have bruh
@@MysteryNotes A fan with 26 buttons/switches
Half my fans go: High - Off - Low, the other half Off - Low - Medium - High.
my fan has 정지, 미풍, 약풍, 강풍
I swear I was just thinking of researching this a day (maybe 2) ago. It made sense for the motor to build up speed to reduce strain on the motor but this explanation makes perfect sense.
this helped me understand the difference in table saw motors! and also some of the noise differences.
Fan designer: "We must put High first for safety" Also fan designer: *Makes a spinny finger-muncher*
Back in the day where if you stuck your finger into spinning blades and lost a finger, that's Darwin telling you it's your fault. Their motto: "Safety third!"
The safety of their warranty department.
My grandparents had one of those heavy, metal fans with barely any grill. They look worse than they are. The edge around the circumference is always protected, and if your hand approaches the blades from the front, it will most likely be pushed back due to the angle of the blades. It's only a problem if you come at it from behind, where the leading edge will hit you first. I wouldn't let a toddler near one, but for older children and adults, it's fine. You'd really have to _want_ to injure yourself with them.
@@ironcito1101 well, pc fans are pretty much like that (because they're supposed to only be used internally, so without any finger-risk) but I've been able to cut myself 2 or 3 times while working on them when turned on :) (I couldn't shut them off because they were servers, and I didn't make any hardware change anyway)
@@ironcito1101 Oh cool, I'm also a heavy metal fan!
This guy’s rhythms, tone, and terminology makes this the highest quality education I’ve ever seen in terms of helping true novices understand complex topics.

Dude your captions are epic. I’m slightly hearing impaired so I always turn them on where possible, and I love the Easter eggs you’ve slipped into them, ha
Interesting trivia: Electric fans were the first common household electrical appliance. Light bulbs were, of course, first, but this was the first common use of a motor.
There is a bit of overlap with vacuum cleaner and washing machine, but in general due to the cost, electric fans were available earlier, around 1900-1909. The vacuum cleaners were available from around 1908 in mass. And washing machines from around 1915. There were available earlier (as early as 1904), but really only started being used widely around 1925-1928. All due to the cost of course. Same for hairdriers, they only kicked off around 1920.
More interesting trivia Michael. One of the very first electrical appliances was an electric vibrator. This was used in doctor's offices to bring women to orgasm. Years ago women had a lot of sexual hangups and sexual frustration, doctors diagnosed this as hysteria so the women would come in and the doctor would masturbate her, obviously, this took considerable time on the doctor's part so the vibrator was developed. As they use to say "truth is stranger than ficton."
Dildos were up there too. They were made before electric shavers.
@@Norm475 Well, we all know new ideas are always turned to sex early on. The internet is for porn, after all.
Imagine people surprise when some areas went from 25 cycles to 60
Lol Electrical Engineer here. He's not even joking when he says he's simplifying things
When i started to learn electronics i was like, cool, this so logical and easy to understand. At a certain point i gave up and went back to believing it's essentially all magic, infused with lots of maths and some occult quantum stuff sprinkled on top. It's better that way.
i think he screwed up the "breaker box in your home" saying to use two 110 vac for 220 vac and you only get 208 vac .isn't all US homes usually 220-240 coming into box? being two separate 110 vac hot's? I had a 220 compressor and no 220 outlet.but had a 220 line changed to two separate 110 outlets for my washer and gas dryer. they took out the 220 breaker and installed two 110 [20 amp] breakers. I ALSO use these outlets for running high amp stuff outside with a ground fault extension cord. but I made a 220 adapter using those two hots for my compressor. it worked fine. until it did not. IT stalled and melted the motor. expensive mistake. MY biggest stupidity was ,those two hots ,were still going back to two separate breakers and i think only one tripped. so stupid . learned it from a youtube video. stupid.
@Jestivius Jovial_Emperor so what is normally coming into a US. residential home, like for stove and dryer ? would i need a new line from the pole for 240? Now I'm really confused.
I’m a electrical motor technician, I couldn’t agree with you more lol he never even dipped into electrical theory.
immrnoidall you missed the line about it coming in as three phase. Because the phases are 120 degrees apart, the ac voltage between two of them is 208.
Thanks dude, I love your videos, informative & entertaining lol
Thank you. Always that question in the back of my mind....
"Yes, I'm oversimplifying it." I understood 3 words of what he said.
The terrifying part is there are 4 words in that sentence
Yes I’m it
"... and I'm getting deeper than I need to, as always..." That's literally why I watch your videos, keep it up!
Thank for finally answering this! I always wondered why, but never enough for me to look it up.
I watched this video about a year ago and found it quite interesting. I came back today because my stand fan just had a failed kickstart! (Relatively new fan, never happened before, fully plugged in.) Initially I set the switch to medium but it didn't start, turned it off and back on and it started going. Kinda cool to see it happen in-person!
I had an old (60's, 70s?) fan which used to stall relatively frequently. Eventually, I realized dust had gotten into places it shouldn't have an increased the required starting torque. It had no issues after a deep clean
Ok.
Ok.
Ok.
Ok.
Ok.
As an electrical engineer, I feel like you did a really good job of simplifying and explaining it for a layman 😄
As a layman, I feel like I did a really good job of pretending to understand these concepts
Shut up
@@andreipaul968 what?
Lol
@A.J. Ello Uh huh. You donæt understand how relevance works, or?
While I was deployed to Greece, I bought a fan to help cool the room. When I returned stateside,I brought the fan back home. I changed out the electric plug to US type. Because the fan was designed for 50 hertz, I was now operating it on 60 hertz. The fan speed increased significantly, and eventually the plastic fan blades broke off.
Don't know why this was on my feed but definitely loved it. I'll never look at a fan the same again.
you said “this is my biggest fan” like you have a collection of many different sized fans but you are especially proud of this one
It could also be his only fan and he would still be right
I wouldn't doubt that he does
I live in the UK and I have never seen a fan with high next to off, this is a completely alien concept to me! Great video as usual :)
Same as me in Australia, we just have 3 buttons for different speeds on our fans. But I do have a very cheap fan which sometimes doesn't start on low speed at all, it just stalls or takes about 45 seconds to get up to speed.
same, i live in germany, never saw that before. i have a fan with a button that you press to turn it on and a button to change speed, or those clicky buttons idk how to describe but even on fans with turn-knobs its just Off-Low-Mid-High. is this just in the US?
Same in Sweden. I have a desk fan with a rotary power switch which is in the order 0 to 3, with 0 being of and 3 being high, never seen a fan with high after off.
I’m in Singapore, and there are no fans with high next to off that I have seen.(idk, maybe because former crown colony?) They are all just 0, 1, 2, 3 buttons
Also in the UK, I imagine its due to being 240v vs 120v probably maybe gives it more starting torque even on low setting.
Bless you. I have been asking myself this exact question for 23 years.
I FEEL LUCKY THAT I FOUND THIS CHANNEL SOME TIME AGO, ITS BRILLIANT
I want a fan that can have a volume knob, to have "infinite" levels of speed, like a volume knob, it gives you more precision.
It's called a Variac.
I want a fan that goes up to 11.
i want a van
@@hercules5813 Why don’t you just make ten the top setting, and make that a little stronger?
