Title: The Innovations of Marc Lambrechts
Introduction
Marc Lambrechts is a notable inventor based in Kessel-lo, Belgium. He has made significant contributions to the field of motor control technology, holding a total of 6 patents. His work focuses on enhancing the efficiency and functionality of brushless DC motors.
Latest Patents
One of his latest patents is titled "Lead angle detection for BLDC motor control." This invention provides a lead angle estimator that accurately estimates the lead angle of a brushless DC motor. The lead angle is defined as the angle between the phase-voltage-vector of a phase-voltage and the phase-current-vector of a phase-current. The lead angle estimator consists of a sampling unit and a processing unit. The sampling unit is designed to obtain phase-samples, which measure the phase-current. The processing unit estimates the lead angle by calculating the difference of the phase-samples during an extremum period around a maximum or at least the phase-voltage, followed by normalizing the obtained difference.
Another significant patent is the "Method and electronic circuit for stall detection." This method is aimed at detecting stall conditions in a multiphase motor that operates in a sinusoidal micro-stepped mode. The process involves measuring at least one phase current and/or the sum of all phase currents at regular time intervals synchronized with the micro-steps. It calculates the difference between the measured phase current at a specific moment and the previous measurement, as well as the difference in the sum of all phase currents. The series of obtained current differences is then analyzed to generate a stall detection signal.
