Fin

Type of fins

In this section, three choices are available to define the type of fin topology: None, Parallel, Radial.

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

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

Remember: The cooling device “Fin” is not available for outer rotor topology.

Table 1. Fin type topology design area - Fin type available – Case of circular shape housing

1	Default setting: Fin type is « None ». The housing has no fin.
2	Button to select parallel fins.
3	Button to select radial fins.

Table 2. Fin type topology design area - Fin type available – Case of square shape housing

1	Default setting: Fin type is « None ». The housing has no fin.
2	Button to select parallel fins.
3	Radial fins are not available when considering square shape housing. The corresponding button is greyed.

For the parallel type fins, two ways are possible to define the fin dimensions: "Height" and "Extension" options. See the illustrations below.

Table 3. Fin type topology design area – Topology and dimension of parallel type fin

1	Button to select the parallel type of fin with constant height.
2	Button to select the parallel type of fin with constant total extension.
