# Winding architecture

## 1. Preamble

General information: In the software winding datasheet, the parameters written in blue correspond to user input parameters and the parameters written in black correspond to data resulting from computations.

## 2. Terminology – Illustration

 Slot composition 1 Wire (also called strand). 2 Conductor, that also corresponds to a turn section (one conductor = one turn).A conductor is composed with one or several wires in parallel (wires in hand). 2* The hatched area corresponds to the conductor’s useful area. Area which 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).

## 3. Terminology – Application in Motor Factory

 Slot composition 1 Wire (also called strand) 2 Conductor (also called bundle). That also corresponds to a turn section (one conductor = one turn).A conductor is composed with one or several wires in parallel (wires in hand). 3 Coil, which is an assembly of several conductors (i.e. several turns per coil).

## 4. Classical winding architecture - Inputs

The following inputs define the winding architecture

## 5. Sections for building the winding

A scrolling selection bar helps to choose the section in which one can define winding settings.

The winding can be built step by step, one can access the different sections by clicking on the following buttons:

• “Winding” to build the winding architecture
• “Coil” to set how is defined the coil and to see how are filled the slots
• “Insulation” to define all the winding insulations
• “End winding” to define the topology and dimensions of the end-windings
• “X-Factor” to adjust phase resistance and end-winding inductance
• “Potting” to define the topology and dimensions of the potting around the end-winding
Note: “Potting” section is available only when the housing is defined with a frame (circular or square shape).
 Building the coils 1 Section to define the winding architecture 2 Section to define the coil settings 3 Section to define the end-winding settings 4 Section to define the X-Factors 5 Section to define the potting. This section is unlocked when there is a frame
