Title: Wolfgang Hammel: Innovator in Motor Control Technology

Introduction

Wolfgang Hammel is a notable inventor based in Bruchsal, Germany. He has made significant contributions to the field of motor control technology, particularly in the development of methods that enhance the efficiency of three-phase machines. With a total of 12 patents to his name, Hammel's work has paved the way for advancements in motor control systems.

Latest Patents

Hammel's latest patents include a method for determining the rotor position of a three-phase machine without using a rotary encoder and a device for controlling a three-phase motor without using a rotary encoder. These innovations utilize a converter that operates through pulse-width modulation. The converter incorporates model variables for the rotor angle and the current indicator of the three-phase machine. In his method, at least two values are measured that represent the local inductances of the machine. The error of the model rotor angle is determined by calculating weighting factors based on the model rotor angle and current indicator. A weighted sum is formed from the measured values and weighting factors, with an offset value subtracted from the sum.
