Skew

1. Overview



BAR – SKEW design area
1 Selection of the ROTOR subset: MAGNET panel (Click on the icon MAGNET).
2 SKEW tab indicates the tools to define the rotor (magnet) skewing angle.
3 Visualization of the motor radial view with bar topology and dimensions.
4 Visualization of the rotor developed view to visualize the rotor (magnet) skewing.
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”.
