Defining the Stator Data for a Three-Phase Induction Motor

The stator is the outer lamination stack where the three-phase windings reside. In the project tree, double-click Machine > Stator, Machine-Stator-Slot, and Machine-Stator-Winding to define the physical dimensions, slot data, wires, and conductors for the stator.

To define general stator data:

  1. To open the Stator Data Properties window, double-click the Machine > Stator entry in the Project Manager tree on the desktop. (You can also enter values in the Properties section of the desktop without opening a separate window.)
  2. Enter the Outer Diameter of the stator.
  3. Enter the Inner Diameter of the stator.
  4. Enter the length of the stator core in the Length field.
  5. Enter the stacking factor for the stator core in the Stacking Factor field.
  6. Select a Steel Type for the stator core:
    1. Click the button for Steel Type.
      The Select Definition window appears.
    2. Select a steel type from the list, or define a new steel type.
    3. Click OK to close the Select Definition window and return to the Properties window.
  7. Enter the Number of Slots in the stator.
  8. Select the Slot Type:
    1. Click the button for the Slot Type.

      2. The Select Slot Type window appears.

    2. Select a slot type (available types include 1 through 4).
      3. Note: When you place the mouse cursor over the slot type, a schematic of the selected type appears, displaying the slot dimension variables.

      Optionally, check User Defined Slot if you wish to define the slot dimensions using the Slot Editor.

    3. Click OK to close the Select Slot Type window and return to the Properties window.
  9. Enter the number of sectors in the Lamination Sectors field.
  10. Enter the thickness of the magnetic end pressboard in the Pressboard Thickness field. Enter 0 for a non-magnetic end pressboard.
  11. Enter the skew width, measured in slot number, in the Skew Width field.
  12. Click OK to close the Properties window.
