Title: Ewald Fehlauer: Innovator in Synchronous Motor Control

Introduction

Ewald Fehlauer is a notable inventor based in Weiterstadt, Germany. He has made significant contributions to the field of motor control technology, holding a total of 2 patents. His work focuses on methods for controlling synchronous motors, which are essential in various industrial applications.

Latest Patents

Fehlauer's latest patents include a method for controlling a synchronous motor for the implementation of an AC voltage. This innovative method provides a rated value proportional to a desired frequency of the AC voltage, which is related to the rotational speed of the synchronous motor. The rated value is continuously accumulated to generate signal values that are used to address stored function values in a memory. These function values represent at least one AC voltage, which is then converted and supplied to the synchronous motor to generate a rotary field. This process ensures that the frequency of the AC voltage defines the rotational speed of the motor.

Another significant patent involves a synchronization method for a run length-limited (1,7)-code. This method includes inserting a synchronization sequence in the bit-serial sequence of three-bit-wide code words. The synchronization sequence consists of at least three consecutive three-bit-wide code words, with at least six zeros between two ones. This innovation is crucial for maintaining synchronization in digital communication systems.
