    Thank you for making this series of videos about these motors. I recently bought one AND a new clamp meter at the same time. I thought there something wrong with my new meter when I measured the no load current draw of the motor.
    It should have been 0.68A at max voltage: it was actually 2.2A!
    Further testing proved the new meter was accurate and the motor was wrong. The speed and ease with which the seller offered a partial refund suggests they know there is a problem with supplying accurate motors - which I think your video confirms. Thanks.

    Thanks for the video! Could you tell us how much amps are being drawn at 24v with a LOAD? Thanks!

    775 dc motor is 12v right? ZY775

    Where's the 12v 775 motor rpm??

    can we convert of low rpm motor to high rpm,,,

      If you provide more power, yes. But it shouldn't exceed the max voltage the motor can handle. Another way is using gears...

      FaZaLi HaSeEb Tv yes by using gear and pulley

    What's the torque ?

    Interesting. So, to keep similar performance in one vehicle is needed to buy all the motors in one batch from one single page

      I did buy 4 of them in one batch from the same page and they are all different (performance) :(

      Wow! that's very odd... is a gamble buying this motors

      Indeed. Luckily I got 6 of them... I test and use them according to my needs. You can get one that is not powerful enough or it is a killer but you might have to redesign your power source. Simple as that :(

    2:28 notice at the ammeter,it was showing 5.4 ampere

      just for t=0s and after that will be 0.08A

    This is 12 v motor if we use 24 v any problem will occur in this
