  • Publication number: 20240038209
    Abstract: A damping panel includes a first metal and a second metal. The first metal has a first surface and a second surface opposite the first surface. The second metal portion has a third surface and a fourth surface opposite the third surface. A fixed region is where the second surface of the first metal is fixed to the third surface of the second metal. A non-fixed region is where the second surface is not fixed to the third surface. A cavity is disposed between the second surface and the third surface at the non-fixed region. A damping material is disposed on at least one of: at least a portion of the cavity on the second surface, at least a portion of the cavity on the third surface, at least a portion of the first surface, and at least a portion of the fourth surface.

  • Publication number: 20200185982
    Abstract: A stator for an electromagnetic machine includes a first lamination stack defining a first cavity therein and having a central longitudinal axis. The first lamination stack includes a first plurality of mounting ears disposed opposite the first cavity and each spaced apart from one another about the central longitudinal axis. The stator further includes a second lamination stack abutting the first lamination stack and defining a second cavity therein aligned with the first cavity along the central longitudinal axis. The second lamination stack includes a second plurality of mounting ears disposed opposite the second cavity and each spaced apart from the first plurality of mounting ears and from one another about the central longitudinal axis. An electromagnetic machine including the stator and a device including the electromagnetic machine are also described.
