Fin

1. Overview

Access to the “Fin” area is unlocked when a frame is defined, whose shape is circular or square.

How to unlock the “Fin” area ?
1	“Fin” area is unlocked (as well as the “Cooling circuit” area).
2	Selection of a circular shape frame.
3	Selection of a square shape frame.

2. Type of fins

The tools available in the housing tab allow defining the fin topology.

Three choices are available to define this topology: None, Parallel or Radial.

By default, fin type is set to “None”. There is no fin.

	1	Default setting : Fin type is « None » The housing has no fin.
	2	Button to select parallel type fins.
	3	Button to select radial type fins.
	4	Icon to export fin data into *.txt or *.xls files.
Fin type available

3. Parallel type fins – Topologies and dimensions

3.1 Parallel type fin area

Parallel type fin design area
1	Radial view of the motor, including the housing topology with fin topology and dimensions.
2	Axial view of the motor, including the housing topology with fin topology and dimensions.
3	The section fin is selected to define the type and dimensions of the fins.
4	Selected button to define parallel type fins.
5	Two ways are possible to define the fin dimensions: "Height" and "Extension" options. See below illustrations.
6	User input parameters to define the fin dimensions. For more information see below.
7	Button to restore default input values.
8	Button to apply inputs. Pressing the enter key twice applies inputs too.
9	Icon to export frame data into *.txt or *.xls files.
