Continuing the Motor series - with a DIY Encoder test. We’re using a hobby DC motor to spin the DIY Encoder to 3000 RPM. Optical Encoders require precise Electrical and Mechanical interpretation to be accurate. Can our 3D printed Encoder and simple photo-gate keep up at 3000RPM?

I really like your channel and it's helpful to see a channel like yours go into detail in regards to many EE ideas and projects for EE undergrads like me. Just letting you know to keep it up! Your channel has potential to grow with these quality videos

I did something for my capstone that used a motor with integrated encoder. It was a automated pill dispenser careosel. I used the feedback and implemented a fun little PID control loop to regulate the position. Basically making a servo motor. With only 'P', it would act "springy" and you could twist the shaft and feel it fighting back with a spring constant. Letting go it would oscillate like a spring mass system at a few Hz. I could also have added damping with the 'd' term but it was good enough for the application and needed to focus on the other parts that we had a hard time getting to work. I can't remember if I ended up adding an 'I' term

Very Excellent! I hope that through the project we eventually get to a point where you think: "Hmmm that might have worked for me!" I think it would be fun to demonstrate those differences with our controller in a future video!

While you are looking at encoders, I'm trying to find reasonably high resolution absolute encoders with fast output for a motor I am designing (parallel direct would be nice instead of slower serial encoding). I'd like about 1 degree resolution for a 60 degree sweep that can handle at least 10k RPM. Controller will be custom to drive 4 full-H bridges (8 stator poles and 6 rotor) with variable strength quick pulses.

@EEforEveryone 2 года назад

Wowza, that's one heck of an encoder! For sure it's possible- I've seen 10k rpm before.. scary. :) I have memories of gears melting, etc. :) I'll keep an eye out, and let you know if I come across anything! Total aside, your motor project sounds pretty awesome. I hope it goes well!

¿Usaste un circuito de histéresis para el sensor IR?

@EEforEveryone 2 года назад

HI Jorge, great question! There is hysteresis via a Schmitt trigger on the photoDiode - 74-series logic!

@realchristopher4334 2 года назад

Damn! What a fascinating thing to be watched! Hahahaha!

@EEforEveryone 2 года назад

Aha,Thanks Real Chris! I'm glad you enjoyed. Feels good to have some fun in the lab!

Hi... I'm long time viewer of your channel... I just have a crappy question from a long time... don't answer if you don't feel comfortable and simply delete my comment if you want to but are you a trans guy or biological one?

@EEforEveryone 2 года назад

Hi BD! No crappy questions! I was born as a man. I'm certainly not the manlyest man you'll ever meet, but ironically, accepting that makes me more of a man. My guess is that's what you meant by biological? Either way, I hope you're doing well- and you feel good about who you are. There's only one of you in the world, and I'm glad that you're a part of E4E!

@burhanuddin127 2 года назад

@@EEforEveryone certainly you're the best guy,and sorry to ask that question....

@EEforEveryone 2 года назад

Thank you, BD, and don't worry about it. :) I hope you have an awesome day!
