  • Yes you are a very smart boy you are the future

  • Dude! GREAT!! Very clear

    

  • fly back diode AKA clamping diode. In the event anyone hears the term.

  • great work , i learn lots from this vedio.

    keep this work on .

    Thanks

  • Are you doing an tutorials on light speed engine circuit boardz?

  • where is your video on PWM you mentioned in this video?

  • Great Video!

  • Thanks a lot ! keep it up :)

  • Don't give out too many secrets.  If the lay person learns to much I am out of funds :)

  • Yeah, I learned something. Hopefully I can just buy a motor controller that will do all the difficult stuff. :)

  • Great job., very helpful to me

  • Excellent intro - clear simple and extra good for us visual learners. I am using it for my students.

    Thanks mucho - Davo (electronics teacher)

  • are you smart  teacher the best..god bless you .

  • you expane good

  • Videos were clear all explanations were spot on and the outro kept me searching for other videos related! Nice job

  • if your only giving like 9 volts to the motor, why was it sparking?

  • GREAT JOB

  • good job

  • Very interesting indeed and very helpful. Thanks for taking the time to do this, please do more. Thanks again.

  • You explain better than my lecturer!

  • awsome!!!!

  • Excellent, excellent video. I would like to make a sun tracker with two motors under the control of a microcontroller. One controlling pan and one controlling tilt. Would anyone sell this cheaply, already made or would I save a lot of money by buying all the parts myself and putting it together?

  • I want to be smart as you!!!

  • Really awesome, keep up the good work with all your videos! (You better keep making them :P)

  • I just recently got into microcontrollers, and I'm wondering where can you find pic controllers, can they be found in household electronics, I have several mother boards from 20 different types of computers, dvd players, r/c cars or do I have to order pic controllers from the internet, I'd like to know, i have a breadboard on standby...thanks.

  • NerdKits is a source of inspiration .

    Tanks from Spain.

  • thanks for the upload. i like it!

  • how do i work a robot from visual basic application on a laptop ?

  • I like your model of a motor, great stuff!!!

  • Great video,

  • I like what you have done. I would be interested in hearing about a high current 30-50A reversing direction pwm speed controller

  • Excelent video!

  • Subscribe dude.

  • Nice video. I had an asian teacher for energy conversion (machines/motors) and you explained the DC motor very well compared to my teacher. I liked how you touched on various subjects such as H-bridges, PWM, and heat sensors as all of them can be used to improve a motor control design and I have used them all in my designs as well. As for all the advanced topics (such as turn on/off times, power dissipation) usually with today's technology, if you pick the right part, they are not an issue.

  • Great video man, can't wait for the next one :)

  • subscribed dude

  • Awesome video, very well done.

    subscribed.

  • Excellent video. Aside from the initial observations I didn't know any of that information before. I'll be looking forward to working with motors now in future projects.

  • Great job explaining whats going on with motors!

    I had a DC motor with a green thing in parallel with the motor, was this a flyback diode or a filtering capacitor, which one is more common?

  • I'd guess that the "green thing" was a capacitor for filtering electrical noise, but the easiest way to check would be to see if the motor behaves similarly when you switch the polarity of the applied voltage. If the behavior is substantially different, then it's probably a diode, serving as a current path in one direction and limiting the speed. But in all likelihood, it is probably a capacitor. Hope that helps!

  • I would also say it is a capacitor. Most power electronic applications (DC Power supply) involve a capacitor across the load to help with noise/filtering and produce a better looking DC waveform. For simple applications such as this in the video, it is common to have a flyback or freewheeling diode.

    Other applications like H-Bridges solve that problem automatically provided it is operated accordingly.

  • @nerdkits

    I don't understand the #9 circuit... :(

    The spark comes from where? Are you rotating the motor?

  • Excelent as usual. Keep on the good work.
