Title: Michael Friedrichs: Innovator in Torque Sensor Technology
Introduction
Michael Friedrichs is a notable inventor based in Hanau, Germany. He has made significant contributions to the field of torque sensor technology, holding a total of 3 patents. His innovative work focuses on the development of advanced magnetic foils and manufacturing methods that enhance the performance of torque sensors.
Latest Patents
One of his latest patents is for a ferro-magnetic foil designed for a torque sensor. This invention features a magnetic foil that is wound and attached to a rotating shaft in strip form at an angle to the shaft axis of rotation. The magnetic strip is mechanically stressed based on the torque acting on the shaft, generating voltages in two secondary windings surrounding the magnetic strips. The voltages differ due to the varying forces acting on the two strips, providing a measure of the torque on the shaft. The strips are formed from stamped segments cut obliquely from an amorphous tape, which is cast with a profiled cross-machine cross-section that has regions of varying thickness. This tape can be manufactured using a nozzle with a correspondingly shaped orifice opening, through which molten amorphous alloy is discharged onto a moving cooling surface.
Another patent by Friedrichs outlines a method for manufacturing a torque sensor, which shares similarities with his previous invention. The method emphasizes the importance of the magnetic foil's design and its application in measuring torque effectively.
