Latest Patents

Mohamed Hamida holds a patent for a "Method for estimating the electromagnetic torque of a synchronous electric machine." This device is designed to estimate the electromagnetic torque of a three-phase synchronous electric machine that includes permanent magnets. The invention features a first flux estimator with two integrators of electromotive force, which 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 that determines variables to correct the flux estimation. A detector generates a signal to reset initial flux conditions based on the flux estimation when discrepancies between the estimated torque and a setpoint torque exceed a predefined threshold. This patent showcases his innovative thinking and technical expertise in the field.
