Issues while computing the efficiency map scalar control

In a few examples such test leads to errors - error messages and resolution failures (ref.: SLVFXM-16492, SLVFXM-16793).
Note: This test is provided in beta mode.

Efficiency map vector control – Bad computation for Ld

The computation of the d-axis and q-axis inductances has been implemented in the framework of the new test Effciency map – vector control U-I.The computation of Ld via the d-axis flux linkage response surface gives bad results (ref.: SLVFXM-17679).

The flux density is not displayed in accurate mode computation

While computing a working point (U, f, N) for an induction machine with a skewed squirrel cage and outer rotor, the flux density inside the airgap is not displayed. (ref.: SLVFXM-16154).

Scalar Maps or Efficiency map (U,f) tests fail with hairpin winding technology

Sometimes, the tests Scalar Maps and Efficiency map (U,f) are not correctly solved with a hairpin winding configuration, like for the Motor M1 of the reference catalog (ref.: SLVFXM-15843).

Scalar maps test can provide bad results

Warning: This test is still in beta mode (ref.: SLVFXM-17587).

Issue while computing the efficiency map (scalar control – U, f or U, I)

This problem occurs when there are 3 poles represented for the periodic portion of the model under consideration (ref.: SLVFXM-17150).

Torque slip curve

Test results are not continuously consistent over a torque slip curve. This occurs with the test Performance mapping T(Slip) - induction machines with a skewed squirrel cage. When the user targets a working point as an added value to be computed with the whole Torque-slip curve, sometimes this additional working point doesn't belong to the curve (ref.: SLVFXM-12599).
