Skew

1. Overview
BAR – SKEW design area
1 Selection of the ROTOR subset: BAR panel (Click on the icon BAR)
2 SKEW tab indicates the tools to define the bar skew angle
3 Visualization of the motor radial view with bar topology and dimensions.
4 Visualization of the rotor developed view to visualize the bar skew
5 Choices to define a skew: None – Continuous (Continuous in our example)
6 Skew inputs to be defined
7 Buttons to restore the default input values
8 Buttons to validate the inputs (Pressing the “enter key” twice applies inputs too).
9 Skew outputs (read only)
10 Button to export the skew data into *.txt or *.xls files.

2. Set a skew angle
How to set a skew angle?
1

Choose the definition mode of the skew:

Stator slot – Rotor slot – Shift angle
2 Definition of the skew angle depending of the definition mode
3 Visualization of the chosen skew angle on the machine radial view
4 Visualization of the equivalent axial slot angle on the rotor developed view
5 Equivalent axial rotor slot angle (read only)
6 Equivalent stator slot pitch (read only)
7 Equivalent rotor slot pitch (read only)
Note: The user can add a skew angle on the rotor or on the stator. If a skew is already defined in the stator when setting a skew on the rotor, the stator skewing will be automatically reset to “None”.
