• For this example currents were selected that are part of the interpolation points 5, 9, 13, and

15, and a measurement at rated motor current was carried out:

[5-24] Saturation characteristic: Distribution of the interpolation points

4. Create a characteristic based on the values calculated for Vp.

• Here, the values which have not been adjusted must be determined by interpolation

between two values.

• Note: In this example it was assumed that the inductance does not change considerably

below 3.75 A. For this reason the same Vp value resulting from a measurement with a motor

current of 3.75 A was used for all interpolation points below 3.75 A.
