Title: Mathias Lehmeier: Innovator in Electric Drive Technology
Introduction
Mathias Lehmeier is a notable inventor based in Neumarkt, Germany. He has made significant contributions to the field of electric drive technology, particularly through his innovative patent. His work focuses on improving the efficiency and performance of electric machines.
Latest Patents
Lehmeier holds a patent titled "Parameter identification for induction machines." This invention presents a method and control apparatus for determining parameters essential for controlling an electric drive equipped with an electric machine. The patent enhances the start-up process of the electric drive by utilizing a current indicator as a signal at the three-phase winding connections of the electric machine. It involves measuring the d-component and q-component of both the stator voltage and stator current at these connections. The process includes two measurement steps: first, applying a rotating current indicator to the winding connections while orienting the electric machine to minimize the exciter current in the q-axis. Second, when the rotor is stationary, a field winding is short-circuited, and a binary noise signal is applied to the winding connections to determine the stator impedance as a control parameter.
