Lamination

Overview

The tools available in the lamination tab allow in defining the outer shape of the lamination.

Three choices are available to define the lamination topology: None, Circular or Square.

By default, the outer shape of the lamination is defined by considering the outer diameter of the stator (defined in structural data).

When the choice of lamination is “None”, original structural data of the stator are considered.

In that case outer shape of lamination is circular without extensions. Outer dimensions of lamination are indicated in general data (structural data part). See illustration below.

Original structural data of the stator: Outer and inner stator diameters

Circular shape lamination

	1	Choice of a circular shape lamination
	2	Additional lamination extension.This corresponds to a diameter extension from the original stator outer diameter defined in the general data (structural data of the machine). See illustration below.For new design, this input won’t be available anymore.
	3	Button to restore default input values.
	4	Button to Apply inputs. Pressing the enter key twice applies inputs too.
	5	Icon to export lamination data into *.txt or *.xls files.

	1	Extension = Diameter extension from the original stator outer diameter. Note: For new design, this input won’t be available anymore.
	2	Original stator outer diameter defined in the general data (structural data of the machine).

Square shape lamination

Main inputs

	1	Choice of a square shape lamination.
	2	Corner type available (Right, Chamfer, Fillet).
	3	Button to select “fillet” type corner.
	4	Button to select “chamfer” type corner.
	5	Button to select “right” type corner.
	6	User input parameters to define the angular shifting of the stator. Note: For new design, extension won’t be available any more.
	7	Button to restore default input values.
	8	Button to apply inputs. Pressing the enter key twice applies inputs too.
	9	Icon to export lamination data into *.txt or *.xls files.

Definition of the slot angular shift

With a square shape lamination, it is possible to set a slot angular shift. It is advised to keep an angular shift lower than one slot pitch.

This parameter allows adjusting outer dimension (D) between outer border of the lamination and the bottom part of slots. For more details see the illustrations below.

Square shape lamination - Definition of the slot angular shift = 15.0 i.e. half value of the slot pitch.

Square shape lamination - Definition of the slot angular shift = 0 i.e. original default value.
