Title: The Innovations of Hassan Lamsahel
Introduction
Hassan Lamsahel is a notable inventor based in Friedrichshafen, Germany. He has made significant contributions to the field of motor control systems and asynchronous machines. With a total of five patents to his name, Lamsahel's work reflects a deep understanding of electrical engineering and innovative design.
Latest Patents
One of Lamsahel's latest patents is a motor control system. This system includes a controller that receives a demanded motor current and produces an intermediate voltage demand signal. It also features a voltage demand signal correction means that generates a voltage demand correction signal. The combining means then combines these signals to produce an actual voltage demand signal applied to the motor through pulse width modulation of the switches in a motor bridge driver. This correction signal effectively compensates for unwanted non-linearities caused by interlock delays in the switching of the motor bridge switches.
Another significant patent is a method, computer program product, and system for operating an asynchronous machine. This method involves closed-loop control of both a first and a second three-phase winding using distinct closed-loop control methods. The second method supplies a voltage vector to a second inverter device and transitions from a closed-loop to an open-loop control method. This innovative approach includes supplying a reference current vector to a filter device, calculating an electrical angle, and transforming control deviation vectors into voltage vectors for the operation of the three-phase winding.
