LapCoil UDP

The LapCoil UDP is used to create a coil for lap-type distributed AC windings or lap-type DC commutating windings in a slotted core created by the SlotCore or VentSlotCore UDP. This UDP can also create a coil cross-section used as a terminal for current assignment.

Property	Description

A single coil is much easier to be described with a slot core as reference. In the following figures, coils are in gray and slot cores are orange. The lap coil’s InfoCoil property is set to 1 to use a single coil to show parameters of lap coil.

This first figure shows a Single Lap Coil with Coil Pitch set to 2:

This next figure shows a Single Lap Coil with Coil Pitch set to 4:

Axial Single Lap Coil with Coil Pitch set to 4:

Below is an axial view of an outer core winding with bended end coil. The lap coil’s InfoCoil property is set to 0.
