Defining the Rotor Pole for a Claw-Pole Alternator

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 tree on the desktop. (You can also enter values in the Properties section of the desktop without opening a separate window.)
  2. Enter the pole embrace at the pole tip in the Tip Embrace field. This value must be between 0 and 1, exclusive.
  3. Enter the pole embrace at the pole root in the Root Embrace field. This value must be between 0 and 2, exclusive.
  4. Enter the pole thickness at the pole tip in the Tip Thickness field.
  5. Enter the pole thickness at the pole root in the Root Thickness field.
  6. Enter the Pole Length.
  7. Enter the Slot Depth.
  8. Enter the Shoe Thickness.
  9. Select the type of magnet to use in the rotor pole from the Magnet Type drop-down list.
  10. If a magnet is being used, enter its length in the Magnet Length field.
  11. Enter the width of the second air gap in the Second Air Gap field.
  12. Click OK to close the Properties window.
