    good video but should the positive and negative connector be changed? the north magnet is attracted to the positive side(because positive is south) and the south magnet is attracted to the negative (Because negative is north).

    I dont think this DC motoro will work unless you switch the terminals.

    please upload more videos.
    They r awesome

    should the armature be spinning the other way? by the right hand rule the side with the current going away should have moved up, not down?

    that was very nice

    thank u for your explanation

    This is a fucking gift

    Thank you very much. You are real guru in the electrical machinary. Your awesome video helped me understand & remember these knowledge easily

    good work.

    In the DC motor, do axles on both sides of the motor spin, or only 1 side? When I buy generic motors, only 1 axles is exposed and moving. Would love it so that axles stuck out both sides of the motor!

    Great video, thank you.

    Hard to believe somebody that can make their own voltmeter would stop a saw blade with their hand

    I watched a video on youtube, It said that "when you put a loop with a current through it (DC current) in the permanent magnet, the rotor start to rotate because of the torque, based on the lorent law" but in this video, you say rotor rotate because the two poles of magnet of stator attract the two poles of coil, This problem make me feel quite confused, please help! Tks you and love you!

    thanks you very much! it's understandable much more the other videos I watched

    i couldn't be more fascinated. great video. are all induction motors brushless?

  19. cepson October 1, 2015 at 9:08 pm

    Very nice. Simple, yet instructive.

  20. stef dolan October 1, 2015 at 9:56 pm

    I have been watching every other video hosted by engineers with fancy animations explaining how the motors work and your video is the best by far. Thank, I know I will pass my electrical test tomorrow

  21. Andrês Santana October 1, 2015 at 10:08 pm

    really nice video!

  22. karun mathews October 1, 2015 at 10:43 pm

    If the whole idea is to magnetise the copper core then why not attach the to wires to the two sides of the magnet? Or why not just put another magnet inside the motor?

  23. shan alvi October 1, 2015 at 11:28 pm

    Pleace make a video on how you make voltage regulator

  24. rovannon October 2, 2015 at 12:27 am

    I like your stuff but man you are a bit creepy:)))))

  25. James James (BuyAussie) October 2, 2015 at 12:54 am

    very nice explanation. thanks!

  26. Ganesh man Lama October 2, 2015 at 1:09 am

    You are just good for your explanation. Very easy to understand.Thanks a lot.

  27. Telmo Monteiro October 2, 2015 at 1:10 am

    You do explain things well! This is good stuff! Thank you!

  28. Will Merritt October 2, 2015 at 1:46 am

    I know this is a old video but my question is what actually goes on when you want to run the motor in reverse?

  29. Mohammad Tamim October 2, 2015 at 1:50 am

    Very useful,
    Many thanks for sharing, …
