A Beginner's Guide to Choosing & Using Motors, Servos and More

[@grigorigahan]

it's hard to overstate how great this video format is. So many maker videos go into 'how' to do something or or show off something very complex they did. Videos like this that break the why in simple terms for a general audience are so so rare.

Big ol' thanks 💜

an actual hidden gem of a channel

[@GrandTheftHollow]

absolutely criminal that this video doesn't have hundreds of thousands more views. great and informative, thank you!

[@TheMightyWej]

Genuinely one of the more intuitive explanations for these topics I've ever heard. I already knew most of the concepts before watching this video, yet somehow I still feel like I understand them more after your explanations. The luggage scale tip is just pure genius! Keep it up man 👍

[@diyoregonnowtexas9202]

Thanks! I'm retired now and want to learn some basic stuff like this for fun projects to mess around with. Ive realized there's quite a learning curve.

[@Core-Electronics]

Sort of thing you only need to learn once though!

[@goldenrebel1st]

That was excellent! So clear, concise and helped my understanding greatly.

[@johnrichardson1949]

Bravo- this is by FAR the best video on this subject ever- and I am a super nerdy old dude

[@phillipesch7556]

I was looking for a video about laser cutting and stumbled upon this....AMAZING, thank you brother I learnt more than i seeked in my search!

[@bausHuck]

Sweet video. Clears up a lot. I want to put a motor on my chain winders on my windows. From this video it seems like a stepper motor is the way to go. Now, I just need to work out a control and maybe a wifi part so I can control it from my phone.

394 likes? Im 3 minutes in and your ability to explain; clear indication of mastery. New subscriber here despite not having seen any of your other videos :) But things could change of course :)

[@Core-Electronics]

Thank you for the kind words! Our other content is more hands on how to achieve a certain thing but glad you enjoyed!

[@hacklucifer]

Thank you very much, you show a lot of base concepts, which can help beginner realize these motors to learn

[@thechadprogrammer5681]

Extremly good explanation with examples. Thank you!!!!

[@tayronamv5687]

great video thank you

[@CharlesShopsin]

This was a great video! Super informative, and well-paced. Also very impressed with your ability to nonchalantly write backwards on the glass board!

[@drfritz142]

Great video. I mean really well done! 🎉

[@michaelmarrinan9981]

Brilliant video so healpful and well delivered. Working on a project where a small lightweight camera will switch between multiple discrete positions by rotating horizontally. I’m guessing a servo motor is the right choice? Would like to avoid using an encoder if possible

[@Core-Electronics]

Definitely sounds like a servo would be the best pick, just ensure you pick a large enough size to move it!

[@bobbybain2576]

This video was so helpful for me, thank you!

[@SmeeUncleJoe]

Great presentation,

[@thefraw]

Yewwww fuck yeah mate, love the vid, love the channel. I'm from the central coast and I love hearing aussies explaining electronics.

[@Core-Electronics]

Thanks for the support!

[@ah-lx9xi]

Interesting, are there linear actuators capable of 100 Hz continuous running?

[@garmiellis]

Hi! You would call a stepper motor the motor of our powered side mirrors of rhe car, which go up down left and right, or those have another specific name? I'm trying to find a mini motor of this kind to move my rear view camera to specific positions. Thanks for your help.

[@Core-Electronics]

It can vary but a car side mirror is often actually a regular dc motor with a very complex gearbox and housing to move the mirrors, the lines of where you can apply things get blurry like that! If you need to move a camera to certain positions then it sounds like a servo might be your bet as you can accurately move the motor to a fixed position. Setting up a pan left and right wouldn't be too difficult, but if oyu wanted left right up down, then that might throw some complexity into the mix.

[@garmiellis]

​Thanks for your quick reply! In that case, it mightbwork if i get a way to attach 2 servos mounted perpendicular to one another, thst way I can succeed with the 4 movement directions. .. i guess in thisncase I would need 2 joystiks.... If I succeed with the gadget Ill show i tto you guys. Thanks again for your imput. ​@Core-Electronics

Great video

[@BastHoen]

Excellent video, thx!

[@MStoica]

Just started looking into Arduino and motors. And I’m confused… From what little info I’ve read so far, nothing mentioned that servos only rotate 180. My understanding was that the main reasons for deciding when you need a servo over a stepper motor is if you need more torque and higher speeds (rpm) then you’d chose a servo. But then, how is a servo useful at all if it doesn’t rotate continuously? if it only does a 180 degrees rotation… Do you have a more detailed video about servo motors? Kind of hard to find videos that aren’t 5-6-7+ years old (I don’t want to watch outdated videos using technology from many years ago, I don’t know if outdated info would help me in any way and I’m afraid of learning something that’s already outdated)

[@Core-Electronics]

Some servos are able to rotate continuously like a stepper motor, while some can only rotate 180 degrees (you can also sometimes find some in 270 degrees, 90 degrees). With a continuous rotation, you can ONLY control the speed of the rotation. With the 180 degree one you can precisely control its angle. This is great in situations like RC planes and cars, you want to precisely control the control flaps of an RC plane, or steer the wheels of an RC car to an exact angle - these 180 degree servos are used here. Our written guide has a bit more info on servos you might find helpful: core-electronics.com.au/guides/digital-electronics/servos-steppers-or-solenoids-choosing-an-actuator-to-move-your-project/ If not, don't worry about older videos, servos haven't really changed in the last decade so the information is still good!

[@MStoica]

@@Core-Electronics wow! Thank you for such a detailed explanation!

[@Alex-si1bi]

OMG! 11 Mo!?
