Defining a Three-Phase Induction Motor

The general procedure for defining a three-phase induction motor is as follows:

  1. Insert a three-phase induction motor into an existing or new project.
  2. Double-click the Machine entry in the Project Manager tree to define the general data, such as the number of poles and machine losses.
  3. Double-click the Machine-Stator entry in the Project Manager tree to define the stator geometry.
  4. Double-click the Machine-Stator-Slot entry in the Project Manager tree to define the stator slot dimensions.
  5. Double-click the Machine-Stator-Winding entry in the Project Manager tree to define the stator windings and conductors.
  6. Double-click the Machine-Rotor entry in the Project Manager tree to define the rotor geometry.
  7. Double-click the Machine-Rotor-Slot entry in the Project Manager tree to define the rotor slot dimensions.
  8. Double-click the Machine-Rotor-Winding entry in the Project Manager tree to define the rotor conductor, ventage hole dimensions, and skew.
  9. Double-click the Machine-Shaft entry in the Project Manager tree to define the magnetism of the shaft.
  10. Optionally, right-click the Machine entry in the Project Manager tree and click Insert Housing to add a machine housing.
  11. Right-click Analysis in the project tree, and click Add Solution Setup to define the solution data.
  12. Choose File > Save to save the project.
  13. Choose RMxprt > Analyze to analyze the design. Note
Note: When you place the cursor over an entry field in the data windows, a brief description of that field appears in the status bar at the bottom of the RMxprt window.

Once the design is analyzed, the model can be viewed in the Maxwell 2D Modeler, or it can be used to create a new Maxwell 2D project, and a new Maxwell 3D design.
