  • @uddipmitra
    @uddipmitra 5 років тому

    Good explanation overall. The one thing that struck me is that I thought one should apply the right hand rule to determine the magnetic pole when current flows through a coil. The author applies the left hand rule.

    • @HomoFaciens
      @HomoFaciens  5 років тому +1

      As explained in the video, the left hand rule is true when considering the flow of negative charges (elctrons). Considering the conventional current (flow of positive charges) you must use your right hand. In the video I am using red balls to illustrate conventional current (flowing from positive to negative) and blue balls to illustrate what it looks like when considering the flow of electrons (from negative to positive).

    For unipolar motors araging the steps in the order 1,2,3,4 would have been far easier to follow. Like this it just makes it look more complicated. Check the datasheet of KH42JM2. it shows the steps very clear and nice.

    • @HomoFaciens

      Well, three phases are the simplest type of unipolar motors and it's similar to brushless motors. That's why I have chosen this type. I keep your idea in mind.

      +Alex Echeverría I guess this isn't a "normal" stepper motor, but a DC motor with an encoder. Try to find a datasheet for this type of motor. Have a look at the working principle of closed loop DC motors:

    • @alexecheverria

      You are wright HomoFaciens! At the back of the motor there is a device to count rotation and in the iddle of motor I cannot see what 5 cables are for. I am building a CNC cutter and have real nema17 stepper motors for it. I will use this one for something else as I am not familiar with a way to control it using arduino and Easydrivers. Have to read and look lots of your great videos. Thank you for answering my question.

  • @genepezzulo
    @genepezzulo 9 років тому

    Shouldn't the solenoid poles be inverted with the current flowing in that directions? I mean that north and south of the stator polar expansions should be "coloured" (red and green) in the opposite way to match the field generated by that animated current.
    Unless the blue dots running into wires are electrons.

    • @HomoFaciens
      @HomoFaciens  3 роки тому

      "Right" are bothways of treating current as I am demonstrating in this video!
      When talking about the direction of current, you must also say what current you are talking of. The action of a conventional current (hypothetical flow of positive charge carriers) flowing from right to left is identical to that of electrons (negative charge carriers) flowing from left to right. Its simple like that.
