In a load-commutated synchronous motor, the torque is driven by the currents in the stator windings, and these currents depend on the rotor position. Since the stator phases are star-connected, the static torque generated by two stator phases connected in series and powered with a constant current offers sufficient information to design a suitable current control strategy. The synchronous machine studied has a reverse type of construction. The switching sequence for the current inverter is correlated with the rotor position by magnetostatic simulation in FLUX2D, using the maximization of static torque as optimization criteria. This study also covers a computational method for determining the operating parameters of a synchronous machine using simulation of the Standstill Frequency Response Test (SSFR).
