Insulation

Definition and terminology

Table 1. Illustration of the slot composition

1	Wire (also called strand).
2	Conductor, that also corresponds to a turn section (one conductor = one turn). A conductor is composed of one or several wires in parallel (wires in hand).
2*	The hatched area corresponds to the conductor’s useful area. Area that includes: the wires + insulation + free space. This is not the conductive area.
3	Coil, which is an assembly of several conductors (i.e., several turns per coil).

Circular shape type wire

Here are all the available insulation types

Table 2. Insulation types
Label	Tooltip, note, formula
Wire	Insulation thickness of the wire
Conductor	Insulation thickness of the conductor. Available only for rectangular shape type wire. See the below illustration.
Coil	Insulation thickness of the coil. Available only for rectangular shape type wire. See the below illustration.
Liner	Insulation thickness of the liner
Phase separator	Insulation thickness of the phase separator
Impregnation	Insulation spread inside the slot
Impregnation goodness	Quality of impregnation (percentage of winding impregnation)

Table 3. Illustration of winding insulation for circular shape type wire

1	Insulation thickness of the wire
2	Insulation thickness of the liner
3	Insulation thickness of the phase separator
4	Wedge to close the slot and maintain the winding inside. It is a part of the slot insulation. However, when needed, the wedge must be defined in the slot topology configuration and not in the insulation settings of the winding area.

Rectangular shape type wire

Here are all the available insulation types.

Table 4. Illustration of winding insulation for rectangular shape type wire

1	Insulation thickness of the wire
2	Insulation of conductors. This is available only for rectangular shape type wire when the conductor (i.e., the elementary group of wires in hand) has a rectangular outer shape.
3	Insulation of coils. This is available only for rectangular shape type wire when the coil (i.e., the group of turns inside a layer) has a rectangular outer shape.
4	Insulation thickness of the liner
5	Insulation thickness of the phase separator
6	Wedge to close the slot and maintain the winding inside. It is a part of the slot insulation. However, when needed, the wedge must be defined in the slot topology configuration and not in the insulation settings of the winding area.

Impregnation

Table 5. Illustration of winding impregnation in slot

1	Winding without impregnation. The surface of the slot’s free area is white.
2	Winding with impregnation. The free area of the slot is colored (light yellow). The impregnation goodness is defined by indicating the ratio between the volumes of impregnation material and air bubbles to be considered.
