Defining the Rotor Pole for a Line-Start PM Synchronous Motor

The rotor pole drives the electromagnetic field which is coupled with the stator windings. Use the Rotor Pole Data Properties window to define the rotor pole.

Note: Some of the fields in the Rotor Pole window change, or are inactive, depending on the Rotor Type you select.

To define the rotor pole:

  1. To open the Rotor Pole Data Properties window, double-click the Machine > Rotor > Pole entry in the Project Manager tree on the desktop. (You can also enter values in the Properties section of the desktop without opening a separate window.)
  2. Enter the limited diameter for the magnet ducts in the D1 field.
  3. Enter one or more of the following magnet duct dimensions, depending on the pole type selected: O1, O2, B1.
  4. For all pole types except number 8, enter the width of the rib supporting the bridge in the Rib field.
  5. Select the type of magnet to use in the rotor pole:
    1. Click Magnet Type button.
      The Select Definition window appears.
    2. Select a material.
    3. Click OK to close the Select Definition window and return to the Properties window.
  6. Enter the total width of all magnets per pole in the Magnet Width field.
  7. Enter the maximum radial thickness of the magnet in the Magnet Thickness field.
  8. Click OK to close the Properties window.
