10/1/2004 9.0 New Features July 30, 1999 Low Frequency Electromagnetic Analysis of Motors Work Bench Environment Motor Analysis in the Workbench Environment Upon entering the workbench environment, read in the design modeler geometry stored in motor2_base.agdb. Motor Analysis in the Workbench Environment You should see an end view of the motor geometry. Using the left mouse button (LMB) click on the blue dot adjacent to the triad in the lower right corner of the plot. This should result in the isometric view shown at right. The image can be dynamically rotated as follows: Position the mouse cursor on the display Hold down the middle mouse button (MMB) Move the mouse cursor Motor Analysis in the Workbench Environment Bring up the enclosure tool as shown at right. This will be used to automatically create a mesh of the magnetic domain between and surrounding the imported geometry Note the details that appear in the lower left pane after this selection is made. We will edit these default values. Motor Analysis in the Workbench Environment Click on the individual entries in the right hand column of the details pane and edit them as shown below. Enclosure name changed to “Air” Shape: Cylinder Alignment: Automatic Cushion: 8 mm Target: All Bodies Merge Parts?: Yes Motor Analysis in the Workbench Environment After editing the details, right click on “Air” in the tree. In the drop down list that appears, left click on “Generate”. This will create a cylindrical volume of magnetic domain in which to immerse the imported parts. Motor Analysis in the Workbench Environment In the tree, open the item “1 Part, 5 Bodies” by clicking on the “+” symbol to the left of it. Do the same with the item labeled “part” that appears below it. Note that the single part in the model consists of 5 individual bodies (stator, rotor, magnet1, magnet2, and “solid”). Right click on “solid” and in the drop down menu, request that it be hidden in the display. Note that the display of any individua
