DoubleCage UDP

The DoubleCage UDP is used to create a double squirrel-cage winding in a slotted core created by the SlotCore UDP or VentSlotCore UDP for induction machines with a double squirrel-cage rotor. The created double squirrel-cage winding can also be used as a subtract tool to derive a core with top and bottom slots.

The main difference between double cage and squirrel cage is that a double cage has double slots instead of single slots. The following 2D figure shows the bottom slot, which is connected to the normal slot. The parameters for a bottom slot are similar to those of a normal slot. Other parameters are exactly the same as a squirrel cage.

Note: For parameters such as Skew, FilletType, SegAngle and parameters related to slots, refer to SlotCore UDP parameters.
