ENCODERS - How do they work? - DIY vs Commercial
In many applications, where we use electric motors, we need to know the speed or position of the motor shaft. To do this we use encoders, but how do they work? In this video we will explain in detail how a quadrature encoder works.

Making a balancing cube - CUBLI inspired - Part 1: Setting up a 1 DOF test bench.
Просмотров 33 тыс.4 года назад
In this video series we are going (or at least try) to make our own version of the CUBLI, based on Arduino. Original CUBLI video: ruclips.net/video/n_6p-1J551Y/видео.html In this first part we will make a test bench to test the balancing capabilities of the system in only 1 degree of freedom.
When will you upload the 2nd video, its een 4 years.
Still waiting for next part 2.
Hey, what happen?
please make more videos!
What happened ??? No updates?
Is there a part 2?
Where Is the second part?
I need your advise about how to make this project
Please make another video! 🤞🙏😋
bruh??????
sooo no update?
More about reaction wheel plz
where is parts two?? :c
awesome video, where is part two ?
pmw signal 😂
wow, i dont know how i got to such a small video but here i am.
Well that was a fucking lie. Way to waste 10 mins of my life
Next episode?
Very good video and also waiting new part here. =)
I bought similar looking hall sensors but I can’t get them to work. They don’t seem to detect a magnetic field. I checked the pin layout multiple times to make sure I got it right but nothing works with those. And I don’t understand why u need a resistance
So I just tried to make this balance with this motor and I don't think it is possible. The motor is a very high rpm (1000KV) and low torque motor (torque is much more important for this application). It takes this motor a few seconds(!) to change direction, which I think is because it is a sensorless brushless motor. This means it will just fall over when you try to tell it to change directions. Also you likely need a way to measure the angular velocity of the wheel, eg an encoder, so you can account for that in your control algorithm. There's a few other youtube videos with working examples.
Yeah don't bother with this guy. He probably saw the Cubli video and thought "I can make that" but when he actually tried it he found out it was too difficult and stopped (hence no updates in over a year...)
I have done sucesfully similar project. You can check out here ruclips.net/video/8RsnoAd-GSI/видео.html. For your problem with motor i recommend using pmsm motor, or cheaper and easier - dc motor. We are controlling the torque here, and in dc motors torque is directly related to current (with torque constant specific to the motor), so by controlling the current you can control the torque.
How can I contact you?
Nice video! Hope you will make the next parts soon.
Can you make more parts soon?
