  • Mounting arrangement for an electrical machine
    Patent number: 8890377
    Abstract: A mounting arrangement for locating a stator (10) within a casing (16) of a rotating machine comprises at least one mounting plate (12) adapted to engage with the stator (10) and the casing (16). The mounting plate (12) has a series of discrete apertures (20) therein. The apertures (20) extend through the plate (12) and are arranged in an array to provide a convoluted path which impedes the transmission of the dynamic forces through the plate (12) and into the casing (16). The apertures (20) render the plate (12) more resilient to the dynamic forces that the stator (10) experiences in operation. Each aperture (20) divides the plate (12) into portions which provide anisotropic stiffness in the radial and tangential directions.
    Type: Grant
    Filed: March 24, 2011
    Date of Patent: November 18, 2014
    Assignees: Rolls-Royce PLC, Rolls-Royce Power Engineering PLC
