Foc equation
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 WebThe Field Orientated Control (FOC) [1][3] consists of controlling the stator currents represented by a vector. This control is based on projections which transform a three …
