Skew

Type of skew

The design of the pole can be considered with or without skewing. Hence, two solutions are proposed:
  • None: The pole is not skewed.
  • Continuous: The pole is designed with continuous skewing.
    Table 1. Pole – Skew - Design area - Skew type available


    1 Default setting: skew type is « None ». The pole is not skewed.
    2 Button to select a skewed type of pole.
    Note: The user can add a skew angle on the rotor or on the stator. If a skew is already defined in the rotor when setting a skew on the stator, the rotor skewing will be automatically reset to “None” and vice-versa.

Continuous skew

Table 2. How to define a continuous skewed pole?


1 Choose the definition mode of the skew: Three choices are possible:
  • Stator slot pitch ratio
  • Rotor pole pitch ratio
  • Shift angle
Note: whatever the definition mode is, the resulting shift angle must be an element of [-180.0, 180.0] (deg).
