Defining the Stator Pole for a General DC Machine

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

To define the rotor pole:

  1. To open the Stator Pole Data Properties window, double-click the Machine > Stator > Pole entry in the Project Manager tree. (You can also enter values in the Properties pane of the desktop without opening a separate window.)
    2. Note: For a two-pole machine, a pole embrace of 0.75 yields a magnet with a span of 135 degrees (based on 0.75*180 degrees).
  2. Enter the inner diameter at the pole center in the Dmin field.
  3. Enter the diameter at the pole tip in the Dmax field.
  4. Enter the width of the pole arc with a uniform air gap in the Bp0 field. For an eccentric air gap, enter 0.
  5. Enter the width of the pole tip in the Bp1 field.
  6. Enter the maximum width of the pole shoe in the Bp2 field. This field is only available for a Pole Type of 1.
  7. Enter the minimum width of the pole shoe in the Bp3 field. This field is only available for a Pole Type of 1.
  8. Enter the size of the pole shoe fillet in the Rp0 field. This field is only available for a Pole Type of 2.
  9. Enter the fillet between the pole shoe and the pole body in the Rp1 field. This field is only available for a Pole Type of 2.
  10. Enter the pole shoe height in the Hp field.
  11. Enter the pole body width in the Bm field.
  12. Click OK to close the Properties window.
