One nice way to visualize
the windings is to right

then select Plane6 from
the tree, then click apply
(step 3 at right). This
positions/orients the
windings so that

After the winding specifications have been defined, create the winding by right clicking on “Winding” in the tree and left clicking on “Generate” in the drop down list.
• 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.
