• FD2: Slot Angle => 22.5
• Clash Detection? => Yes
Setting clash detection to “yes” will bring up another row called “Bodies for Clash Detection” in the winding details pane. Click the cell to the right, highlight “rotor” in the tree, and click Apply. This will trigger a check for interference between the defined windings and the rotor stack.
