Customized step skew

Table 1. How to define a custom step skew?

1	Custom step skew definition mode.
2	Click on the button “Set values” of the field “Step skew description” to open a dialog box to define the custom step skew. Refer to the section that illustrates how to fill the Custom step skew table via the dedicated dialog box.
3	Virtual magnet opening to adjust the axial view to any size of magnet opening - It must be included in the range of ]0;180] degrees.
4	Equivalent stator slot pitch (read only).
5	Equivalent rotor slot pitch (read only).
6	Visualization of the machine-developed view resulting from the axial slot angle, the number of layers and the virtual magnet opening.
7	Visualization of the chosen skew angle on the machine radial view.

This section illustrates how to fill the customized step skew table via the dedicated dialog box.

Once clicking on the button “Set values” of the field “Step skew description” the following dialog box is opened.

Table 2. Step skew description – Dialog box to define the customized step skew

1	Browse the folder to select an Excel file in which is described the custom step skew configuration.
2	Button to refresh the table data when the considered Excel file has been modified.
3	Fields to be filled with data to describe the step skew configuration to be considered.
4	Button to validate the inputs (Pressing the “enter key” twice applies inputs too).
5	Button to empty the table contents.
6	Button to close the dialog box. The last modifications are not considered.

Note: The first value of the shift angle must be “0”.

Note: The shift angle of each layer (or index) refers to the reference axis given by the dash line in the axial view (position of the first layer).

Note: The sum of the thickness of each layer must be equal to the rotor length.
