  • Publication number: 20250216460
    Abstract: 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.

  • Patent number: 12348100
    Abstract: 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.

  • Publication number: 20250175064
    Abstract: In a method for impregnating a winding system arranged in substantially axial slots of an electromagnetically conductive element of a stator of a dynamoelectric machine, the winding system is impregnated by impregnation resin using a dipping or trickling process. Vibrations are induced into the stator and/or the impregnation resin over a specifiable period of time with an adjustable amplitude and/or frequency, and the stator remains at rest in a dipping tank for a specifiable time after the vibrations have been induced.

  • Patent number: 12316175
    Abstract: Disclosed is a method for pulling a stator winding system of an electric machine into a stator lamination stack of the electric machine and to a winding tool, with the stator lamination stack having stator grooves which run parallel to a rotation axis of the electric machine and are distributed in a circle around the rotation axis and open thereto and which have on an end facing the rotation axis a gap region which is narrowed relative to the rest of the stator groove. Windings are arranged in the stator grooves, and winding overhangs, as seen in the direction of the rotation axis, protrude from the stator lamination stack at the two axial ends thereof, with the windings formed in the stator grooves as laid windings. The stator lamination stack has no guide structures on the two axial ends for guiding the individual turns of the windings.

  • Patent number: 12074484
    Abstract: A component for an electric machine includes a flat region in which an electric line runs when the component is integrated into the electric machine and which includes a sharp-edged structure. A polymer layer adheres to the flat region without further aid such as to mask the sharp-edged structure and thereby protect from damage the electric line on the flat region. The polymer layer is made of cured plastic adhesive and jetted onto the flat region in the form of threads, such that the threads are spin-coated on top of one another in the form of overlapping loops and form a network structure which spans the sharp-edged structure.

  • Patent number: 11967869
    Abstract: Various embodiments include a passive component comprising: a substrate; and two conductor tracks disposed on the substrate. The substrate forms an electrically insulating bridge between at least two phases of an electrically rotating machine. Each of the two conductor tracks is coupled to a separate phase of the at least two phases so an electrical potential across the electrically insulating bridge is the same as in the insulation system of the machine and the potential load on the passive component corresponds to the potential load on the insulation system.

  • Patent number: 11522424
    Abstract: 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.
