Manually Specifying B-P Curve Coordinates
To manually specify the loss characteristics (B-P Curve):
-
In the View/Edit Material window, set the Core Loss Model of the material to Electrical Steel or Power Ferrite.
When you do so, this enables the Calculate Properties selection for the drop-down menu at the bottom of the window.
-
Select either Core Loss at One Frequency or Core Loss versus Frequency from the drop-down menu to open the B-P Curve window.
-
Select Core Loss Coefficient from the Calculate Properties for drop-down menu to open the BP Curve dialog box.
-
In the BP Curve dialog box, enter B and P values in each row of the Coordinates table.
-
To add or edit rows, click the following buttons:
- Add Row Above
- Add Row Below
- Append Rows (In the dialog box that appears, specify the number of rows to append to the table, and click OK.)
- Delete Rows
Note: The value of B
must increase along the curve. Placing the cursor in the field in the Coordinates table enables the Add Row and Delete
Row buttons.
As you enter values, the graph is updated.
