【正文】 n the Workbench Environment Add a request for calculated values of “Total Flux Density” on all bodies (the default). 2 1 New Features Workshop ANSYS 10/1/2022 37 Motor Analysis in the Workbench Environment Add a request for calculated values of “Directional Force/Torque”. 2 1 New Features Workshop ANSYS 10/1/2022 38 Motor Analysis in the Workbench Environment Set “Orientation” in the details pane to “Z Axis” (., calculate torque about the global z axis). Click on the cell to the right of “Geometry” in the details pane and left click in the vicinity of the rotor centroid. You will see a number of “sheets” appear in the display. Left click on these one at a time until you find the one associated with the rotor (the rotor will be highlighted in green as shown at right). Click “Apply” as shown. The rotor should be displayed in a dark blue color. 2 1 3: Click around here 4: Cycle through “sheets” until the rotor is highlighted in green 5: Click Apply New Features Workshop ANSYS 10/1/2022 39 Motor Analysis in the Workbench Environment We have specified nonlinear BH data for the rotor and stator but will suppress its usage so that the solution can be obtained expediently. Choose “Rotor” in the tree and set “Nonlinear Material Effects” to “No” in the rotor details pane. Do the same for the stator (shown at right). 1 2 New Features Workshop ANSYS 10/1/2022 40 Motor Analysis in the Workbench Environment Execute the linear solution as shown at right. 1 2 New Features Workshop ANSYS 10/1/2022 41 Motor Analysis in the Workbench Environment One the solution has pleted (~1015 minutes), you may select an individual body for postprocessing. For example, to view results on the rotor, right click on it in the tree and click on “Hide All Other Bodies” in the drop down list. 1 2 New Features Workshop ANSYS 10/1/2022 42 Motor Analysis in the Workbench Environment Selecting “Total Flux Density” in the tree produces a contour plot of the magnitude of the B field in the unhidden part(s). The B field may also be plotted as vectors by clicking on the vector graphics button. This button toggles between contour and vector displays. 1 2 1 2: Access vector plot representation New Features Workshop ANSYS 10/1/2022 43 Motor Analysis in the Workbench Environment You may also experiment with the vector plot controls. Vectors may be “element aligned” (one per element) or “grid aligned” (displayed with a user selected density). Length may be scaled for better visibility. The wire frame button makes the body transparent so that the vectors within the volume of the body may be visualized. Magnitude scaled 3D arrows Wireframe Display Grid aligned New Features Workshop ANSYS 10/1/2022 44 Motor Analysis in the Workbench Environment A contour of the z ponent magic forces and rotor torque about the global z axis may be produced as shown at right. 1 Net Torque
