WebJan 16, 2024 · To make this reference-frame transformation work, it is necessary to measure the rotor position directly using speed or position sensors (sensored FOC) or infer it indirectly (called sensorless FOC). FOC does this and calculates the rotor flux angle at a kHz rate to then control the currents in the stator windings WebFor currents in a motor with balanced three phase windings, these measurements provide values iaand ib. icis calculated by the following equation: ia+ ib+ ic= 0. 2. The three-phase currents are converted to a stationary two-axis system. This conversion provides the variables iα and iβfrom the measured ia and iband the calculated icvalues. dave biagi home repairs
