SSFR

Positioning and objective

The aim of the test “Characterization – Model – Motor – SSFR” dedicated to the wound field synchronous machine is to characterize all the parameters of the D-axis and Q-axis equivalent schemes by performing a frequency analysis.

Figure 1. Characterization – Model – Motor – SSFR” – Characterization of all the equivalent scheme parameters D-axis and Q-axis equivalent scheme data – 2nd order is considered in the example above. Reactances and time constants of the machine are computed

These results are based on the magnitude and the phase of the operational inductance transfer function which are computed with Finite Element software Altair Flux 2D.

The resulting reactances and time constants of the machines are also provided. Hence, such data can be used in system modeling tools like Altair® PSIMTM to evaluate the behavior of the machine with its drive and control system.

The following table helps to classify the test “Characterization – Model – Motor – SSFR”.
