Latest Patents
Taherzadeh holds a patent for a "Method for estimating the electromagnetic torque of a synchronous electric machine." This innovative device estimates the electromagnetic torque of a three-phase synchronous electric machine that includes permanent magnets. The device features a first flux estimator with two integrators of electromotive force to estimate the respective components of the flux in a fixed two-phase coordinate system tied to the stator. Additionally, it includes an estimator for calculating the torque from the estimated-flux components, a second flux estimator that utilizes currents in a rotating two-phase coordinate system tied to the rotor, and an observer to determine variables that characterize magnetic uncertainties of the machine. This setup aims to correct the flux estimation of the second estimator. Furthermore, a detector generates a signal to reset the initial flux conditions of the two integrators based on the flux estimation from the second estimator when the discrepancy between the estimated torque and a setpoint torque exceeds a predefined threshold.
