[@elewizard]

Yeah, my mistake 😑

[@AndyDoesJapan]

I spent all day trying to figure out steppers and nothing was more valuable than this video. It truly is the ultimate guide!

[@elewizard]

Glad it helped! Cheers 🍻

[@wulloxske]

Finally a clear and helpful description of how a stepper motor works. Thanks!

[@elewizard]

Glad it was helpful!❤️❤️

[@surviveable]

Best video introduction on stepper motors. Watch this if you’ve never used one and plan to.

[@elewizard]

Glad you think so ❤️❤️❤️

[@hadiumidiyeh]

Yes, as you mentioned in the description, I was confused about the common wire at 12:50. Your videos are very helpful. Thank you so much.

[@elewizard]

Yes, that was a mistake 😑

[@MattyEngland]

I've watched a lot of stepper motor videos, and this is by far the best explanation of the different types 👍👍 Thks very much.

[@elewizard]

Glad you liked it!👍👍

[@dsbohra]

[@doublepmcl6391]

Thank you for your time and making this video. Even I have watched other videos on YT, in this one you are explaining everything step by step. Very NOICE! 😃

[@elewizard]

You're very welcome!❤️❤️❤️❤️

[@AirmanCS]

Your channel is amazing to be so new, pls continue to make videos, they are the best!, I love microcontroller projects, and raw electronics. Arduinos can be either too big, complex or expensive when you are trying to make sellable PCBs

[@elewizard]

Thank you for the compliment ❤️ I will do my best for you I agree with your opinion about arduino 👍

[@hamidsalman2476]

Best explanation ever. Thank you bro.

[@elewizard]

You are welcome, thanks for watching dude

[@gumse666]

I have used microstepping with stepper motor drivers supporting microstepping. But I never understood all the details behind it. Now I do, great video.

[@elewizard]

Awesome, So I hit the target 🎯

[@wizhippo]

Can you in a future video go over selecting an appropriate stepper motor? Perhaps clarify if higher or lower inductance steppers are better or worse? Benefits of driving at higher vs lower voltages? Basic torque expectations? There are soo many on common shopping sites with steppers of varying specs. I believe for most hobby applications such as 3d printers it is hard to too wrong, but I have been had issues in the past not knowing that the steppers I bought had an unusually high inductance as I did not know at the time this should be considered and did not work for my application. Love your videos and the excitement you bring to them!

[@elewizard]

Yeah, selecting right stepper motor for a specific project can be confusing. Maybe some I could make a video on this subject in future

[@jorgeboardman]

[@ChandrashekarCN]

why you are not using black sound absorption foam panels on wall?? it's make you talk even smoothly (also looks good on background ) expected small stepper driver compared with yours. thanks

[@elewizard]

Good suggestion 👍👍👍

[@sudheerkumar5966]

Very good sir

[@elewizard]

Thank you, my friend

[@DesertVox]

Would it be possible AT ALL to drive a 4-wire stepper in a UNIPOLAR configuration, because in theory you can energize each coil using the UNIPOLAR method. Maybe it will have less torque and resolution, but it should be possible, right? Maybe it would be like the 3-wire steppers?

[@IamSholiSJ]

Will this reduce noise as well during motor spin?

[@umesh.kumar.naik278]

Great video... Sir can we drive this with 555/cd4017(using 4 output pin).. I think it will work.. Thank you sir

[@elewizard]

Since cd4017 is a 10 bit counter, NO, normally you can't use cd4017 to drive a stepper motor, if you are determined to use this IC to drive the stepper motor, you will need some other ICs beside cd4017 to make it able to generate stepper motor pulses.

[@alirezarahimi3708]

very nice ❤ i love you arta

[@elewizard]

Thank you so much 😀 my friend

[@KerrySainsbury]

Excellent video, up until you displayed some magic numbers without any explanation of how you determined them. Any video explaining the process you used would be awesome!

[@elewizard]

Trial and error. This is the magic method I used 😉

[@adammontgomery7980]

He did say the torque response is nonlinear when applying pwm. If you just graphed the numbers he gives, you should see the true torque response

[@gauthierostervall4849]

Do you mean the PWM levels of the microsteps? My guess is that these follow the first fourth of a sinus curve. It would make sense, sines and cosines are exactly that: linear coordinates of circular motion.

[@EEFTARUNA]

thank you

[@elewizard]

You're welcome

[@waldtk3000]

In a free society there is no conflict in seeking ones self-interest and the interest of others, but quite the opposite and in a much larger scale. In free capitalist society, one can only succeed by providing goods and services to others that represent a great value to them and at a price they are willing to pay. Before writing “The Wealth of the Nations¨, Adam Smith wrote another book entitled “Theory of the Moral Sentiment”. In a large sense, “The Wealth of Nations” is a continuation - albeit with a larger economic perspective and emphasis - of his previous book (“Theory of the Moral Sentiment”). Also, philosophically, helping others in greater need is in no way alien to our own self-interest; but quite to the contrary, it often comes with a sense of reward and inner self-gratification - thus it is fully aligned with the ideas of Objectivism. However, in no way, does that mean that we put others ahead of ourselves or of our own self-interest.

[@johnbarry8185]

It would have been nice, if you would have shown the way you connected the circuit. Your information is informative, but knowing the schematic, and why the schematic is wired a specific way would be REALLY nice.

[@elewizard]

Yeah, it would be nice but I have to keep the content short and avoid talking about things that are less related to the main subject. Sorry for that😉

[@amir2010r]

you are awesome 👍

[@elewizard]

You too, amir

[@isettech]

There is another category of stepper motor, that appears no different but is much better suited for micro stepping applications. Most stepper motors use a magnet and have combed pole pieces in typical construction. These when power is removed have a considerable magnetic cogging as you can feel every step. For some applications where smooth operation is required, the cog steppes are much less intense. As the driver does not have to fight those steps, when driven with a micro stepper driver, they are much smoother and perform much more closely to a synchronous permanent magnet motor, but with the same number of steps per revolution. The downside is a lower torque, and it has very little force to hold position when power is removed. The upside is the micro steps are much more even in the absence of strong cogging of the motor

[@elewizard]

Thanks for sharing ❤️❤️❤️

[@astroswell]

afaik the stepper drivers are judged by the purity and accuracy of a sine wave they are able to produce. But how is it produced? Is it just a combination of high res PWM and a capacitor?

[@elewizard]

Yeah, driver ICs produce shifted sin waves to smoothly rotating the shaft. It is analog voltage which can be produced by a DAC and buffered by a current booster circuit. Also there are are other methods

[@astroswell]

@@elewizard thanks!

[@Enigma758]

I was taught that using phase shifted sine waves is the best method for microstepping.

[@elewizard]

That is the best way to go for microstepping. As I mentioned in the video, there are several methods to implement this technique

[@maungmaungtint8572]

Thanks

[@elewizard]

Welcome😊

[@jpsilver3510]

So if i understand this correctly i can just get 4 mosfers and run a 4amp stepper motor for $2 instead of getting a $30 stepper motor driver? Also could i use another mosfet to control the torque?

[@elewizard]

Yes, by using 4 transistors you cab make a unipolardriver and by using 8 transistors, you can make 2 h-bridges which is enough to make a bipolar driver. Also you need some other components like flywheel diodes

[@jpsilver3510]

@elewizard ohh awesome! Thank you so much! You are the first person who actually responded.I do appreciate this more than you think! But i think a bipolar driver would be fine. How would I control the torque of the stepper motor if you dont mind me asking? Im busy making a racing sim using some parts i got from an industrial printer. I was successful in creating a rotary encoder using 2 linear hall sensors and a diametric magnet by placing the sensors 90° out of phase. I was also able to create a simple usb circuit that uses pins on an arduino nano, only thing i still need to complete is the force feedback of my steering wheel. Do you think a stepper motor would be fine or would it be better to buy a dc motor?

[@elewizard]

You can control the torque by PWM👍 a stepper motor would be fine, also you can use a DC motor+encoder

[@jpsilver3510]

@@elewizard thank you so much! You where very helpfull and i hope someone else could learn from this too!

[@arvetemecha]

Hello, it might not be cheaper though, cause you might encounter further difficulties like driving your mosfets correctly, because achieving PWM control with quite "high" current mosfets (I mean more than a few mA) out of the ohmic region can be tricky. But anyway, that's part of the fun :-)

[@hazratwalihyderi8521]

[@elewizard]

Thanks🍻

[@elewizard]

It was a mistake, as I have noted on the paper, it the one at left is bipolar and the one at right is unipolar

[@roysigurdkarlsbakk3842]

Thanks for this, but I guess I'll get a tmc2209 instead ;)

[@elewizard]

Yeah, that is a good idea. But this video give you a deep sight of what is going on inside the technique.
