Publication number: 20250216460Abstract: A sensor system for an electric machine includes a sensor/transmitter apparatus arranged in a power connection area of the electric machine. The sensor/transmitter apparatus detects a physical measurement variable associated with the electric machine and to transmit a signal associated with the measurement variable when the measurement variable exceeds a previously defined threshold value. The physical measurement variable is voltage and the sensor/transmitter apparatus is designed to detect overvoltage in the electric machine. The sensor/transmitter apparatus includes a circuit which includes a resistor. The resistor includes a layer which is designed in such a way that a partial discharge in the layer during the overvoltage in the electric machine causes a value of the resistor to increase.Type: ApplicationFiled: April 14, 2023Publication date: July 3, 2025Applicant: Siemens AktiengesellschaftInventors: TOBIAS KATZENBERGER, BASTIAN PLOCHMANN

Patent number: 12348100Abstract: Various embodiments of the teachings herein include an apparatus for voltage equalization in square-wave voltages of electric motors. The apparatus may include: a terminal board circuit wherein phases U, V, and W each comprises input and output cabled conductors summing to at least 6 cables; and a bridge between two of the at least six cables connecting two or more of the at least 6 cable inputs and outputs. The bridge is partially conductive such that its electrical resistance markedly reduces above a threshold value. The partial conductivity results from filler particles in an embedding matrix determining a reduction of the resistance in the bridge above the threshold value.Type: GrantFiled: October 9, 2020Date of Patent: July 1, 2025Assignee: INNOMOTICS GMBHInventors: Tobias Katzenberger, Bastian Plochmann

Patent number: 11522424Abstract: A stator of an electric machine includes a laminated core having slots for receiving windings of a multiphase winding system. The windings have winding ends, which are encased with an insulator across a partial length. In order to encase the winding ends with the insulator, a strand of a thermoplastic material is extruded onto the winding ends via a nozzle. During extrusion, the nozzle is moved relative to the winding end along the longitudinal extent thereof and an oscillating movement of the nozzle transversely to the longitudinal extent of the winding end overlays the movement along the longitudinal extent. As a result the thermoplastic material lies on the winding end and around the respective winding end in the form of loops.Type: GrantFiled: July 30, 2020Date of Patent: December 6, 2022Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Klaus Büttner, Tobias Katzenberger, Klaus Kirchner, Bastian Plochmann, Matthias Warmuth
