Winding insulation

1. Overview - Definition

Here are all the available insulation types.

Label Symbol Tooltip, note, formula
Wire * Insulation thickness of the wire
Conductor * Insulation thickness of the conductor.

Available only for rectangular shape type wire. See illustration below.
Coil * Insulation thickness of the coil.

Available only for rectangular shape type wire. See illustration below.
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).

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.

3. Impregnation

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.

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.

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.
