Defining the Stator for a Three-Phase Synchronous Machine

Use the Stator windows to define the slot dimensions, stacking factors, air ducts, and insulation of the stator. The stator is the outer lamination stack where the three-phase windings reside.

To define general stator data:

1. To open the Stator Data Properties window, double-click the Machine > Stator entry in the project 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 theSlot Type:
1. Click the button for the Slot Type.
   The Select Slot Type window appears.
2. Select a slot type (available types include 1 through 6). Slot types 1 though 4 are filled with round wire. Slot types 5 and 6 are filled with rectangular wire. If Auto Design is enabled, the software designs an optimum slot geometry; in this case, you can input the tooth width dimension, and the software determines the slot width accordingly.
Note: When you place the mouse cursor over the slot type, a schematic of the selected type appears, displaying the slot dimension variables.
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 pressboard in the Pressboard Thickness field. Enter 0 for a non-magnetic pressboard.
11. Enter the skew width, measured in slot number, in the Skew Width field.
12. Click OK to close the Properties window.
