Rotor Skewing

    • junaed.buet

      What is the difference between continuous and step skew in ansys maxwell 2D ? As the number of slice is needed to be given more than 1 in skew model (The result is same for slice 1 for any angle and no skew model), how to get the skew model like the left image below?

      Hi junaed.buet,

      For Maxwell 2D transient designs with cylindrical rotational motion setup, the transient solver can
      take into account the effects of skewed rotor slots by using a multi-slice model.

      Continuous skew, the default, is used for induction motor rotors.

      Step skew is used for permanent magnet rotors.

      The left image(a) in your picture can be represented practically as a sliced model.

      You can refer to the “Model Settings Tab > set skew model options” sections under maxwell help.

      Hello @junaed.buet,

      The main difference between continuous and step option is the way of defining the skew angle. When you choose continuous as skew type, the calculation is still discrete. You could choose a larger number (5~11) for slice number to make it closer to the continuous PM in practice.
