A mounting arrangement for locating a stator () within a casing () of a rotating machine comprises at least one mounting plate () adapted to engage with the stator () and the casing (). The mounting plate () has a series of discrete apertures () therein. The apertures () extend through the plate () and are arranged in an array to provide a convoluted path which impedes the transmission of the dynamic forces through the plate () and into the casing (). The apertures () render the plate () more resilient to the dynamic forces that the stator () experiences in operation. Each aperture () divides the plate () into portions which provide anisotropic stiffness in the radial and tangential directions.
