  • Patent number: 11482910
    Abstract: A stator for an AC motor, includes windings of a first layer, which extend over a first region of the stator and are connectable to a first phase, and windings of a second layer, which extend over a second region of the stator and are connectable to a second phase, wherein the first region is offset relative to the second region and at least one overlap region is formed which is smaller than the individual regions, and wherein a temperature detection unit is arranged in the overlap region and is designed to measure the temperature of the windings in the overlap region.
    Type: Grant
    Filed: August 29, 2019
    Date of Patent: October 25, 2022

  • Patent number: 11108295
    Abstract: A contact ring for a stator of an electric motor has three planes, i.e. a first plane with at least one first conductor; a second plane made of an electrically insulating material; and a third plane with at least one second conductor, and at least one first and one second feedthrough passing through the second plane. The first feedthrough is smaller than the second feedthrough, and the first feedthrough guides coil wires of one coil and the second feedthrough guides coil wires of at least two coils.
