Calculating Properties for Core Loss in RMxprt (BP Curve)

To be able to extract parameters from the loss characteristics (B-P Curve), you first set the Core Loss Model of the material to Electrical Steel as a material property in the View / EditMaterial window.

To calculate core loss properties for an electrical steel material:

  1. Click Tools > Edit Libraries > Materials.

    2. Or in the Project Manager tree, you can also right-click Materials, and select Edit Library.

    The Edit Libraries window appears.

  2. Click Add Material.

    3. The View/Edit Material window appears.

  3. In the Core Loss Type row, select Electrical Steel from the Value drop-down menu.

    4. This enables the Calculate Properties for drop-down menu at the bottom of the dialog box with the following two choices:

    • Calculate Properties for: Core Loss at One Frequency
    • Calculate Properties for: Core Loss versus Frequency

    It also displays parameters associated with Electrical Steel materials.
