  • Dynamoelectric rotary machine with elements for reducing tonal noises
    Patent number: 11539275
    Abstract: A dynamoelectric rotary machine includes a stator, which has a winding system arranged in grooves disposed between teeth of a magnetically conductive body and a winding head on the end faces of the stator in each case. A rotor with a cage ring is arranged rotatably about an axis and during operation of the dynamoelectric rotary machine is in electromagnetic interaction in a motor-driven or generator-driven manner with the winding system of the stator arranged in the grooves by way of an air gap. Comb-type elements are disposed on the end faces of the stator. The comb-type elements assume an extensive intermediate space between the winding system projecting from the end faces of the stator, so that tonal noises which are produced during operation of such an electric machine are at least reduced.
