  • ACTIVE PART OF AN ELECTRIC MACHINE, ELECTRIC MACHINE, AND METHOD FOR PRODUCING A PRE-MOUNTED ASSEMBLY FOR THE ACTIVE PART
    Publication number: 20220329120
    Abstract: An active part of an electric machine, the part being designed as a rotor or a stator for the electric machine, including a main part and a plurality of permanent magnets secured on/in the main part. The active part has one or more securing devices made of sheet metal, each of which holds at least one of the permanent magnets and via which the permanent magnets are secured on/in the main part. A corresponding electric machine and a method for producing a pre-mounted assembly for securing at least one permanent magnet to the main part of an active part of an electric machine, and the use of such pre-mounted assemblies are also provided.

  • Electric machine with variable motor constants
    Patent number: 10826367
    Abstract: An electrical machine includes a stator and a rotor rotatably mounted in the stator. A spindle is guided through the electrical machine. At least one magnetic flux-conductive assembly which can be introduced into the electrical machine is provided. The magnetic flux-conductive assembly is disposed on the spindle in a linearly displaceable manner in order to vary a motor constant of the electrical machine as a result of a displacement into the electrical machine.

  • EXHAUST GAS TREATMENT APPARATUS
    Publication number: 20190232223
    Abstract: A gasoline particulate filter for an exhaust system of a gasoline internal combustion engine includes a substrate and a catalytic coating disposed on the substrate. The catalytic coating has a carrier and at least one catalytically active ingredient. The catalytic coating has a carrier loading less than or equal to 0.5 g/in3 (0.03 g/cm3), and a catalytically active ingredient loading greater than or equal to 0.01 g/ft3 (0.35 g/m3) and less than 2 g/ft3 (70.63 g/m3).
