Creating a Core with Poly Holes

Normally a Shaded Pole Core UDP has only one pair of holes. In order to create a poly-hole Pole Core UDP, you need to use subtraction and move commands. Detailed steps are as follows.

  1. Create a core as described in Creating an Outer Shaded-Pole Core.

    2. Original ShadedPoleCore

  2. Make a copy of the current core.
  3. Select the desired inner core in the history tree, and right-click to choose Edit > Copy.

  4. Then right-click the same object in the history tree to choose Edit > Paste. This process is shown in the following figure:

  5. Change the new object to a Hole filler.

    6. Click on CreateUserDefinedPart of ShadedPoleCore2 object, and set InfoCore property to 5 in the pop-up window. The objects in the coordinate system window are shown in the following figure:

    Change the InfoCore of the second ShadedPoleCore

  6. Move the hole filler to another position for subtraction.
  7. Select the hole filler (ShadedPoleCore2) in the history tree.
  8. Click Edit > Arrange > Move from the menu. The modeler switches to move mode and prompts you for a reference point in the status bar.

  9. Enter a reference point by clicking at the origin. Another option is to enter (0, 0, 0) in the keyboard entry area of the status bar, and press Enter.
  10. Enter a target point along the Z-axis by clicking the mouse along the axis. Another option is to enter (30, 0, 0) in the keyboard entry area, and press Enter, which is shown in the following figure.

  11. Choose the core (ShadedPoleCore1) and the hole filler (ShadedPoleCore2) to make a subtraction.
  12. Select both the core and hole filler by pressing Ctrl on the keyboard.
  13. Click Modeler > Boolean > Subtract to subtract the two selected objects.

  14. In the Subtract window, put core (ShadedPoleCore1) in the Blank Parts and hole filler (ShadedPoleCore2) in Tool Parts.

    15. Select the Blank Parts and Tool Parts

  15. Click OK to finish subtraction. The core look likes the following figure:

Another option is to copy and paste multiple cores, change them to hole fillers and move them to different positions to create a core with more than 2 pairs of holes. The following figure shows a sample hole:
