A turbine generator comprising a turbine rotor comprising a hub and one or more blade stages. Each stage comprising a circumferential array of rotor blades in driving engagement with the hub. A turbine stator comprising a hub and one or more vane stages, each stage comprising a circumferential array of vanes. The turbine rotor and turbine stator being concentrically arranged about a common axis to define an annular flow path. The vane stages and blade stages being axially spaced along the axis and having one or more magnets arranged on the rotor. A generator stator concentrically aligned with the turbine rotor and turbine stator and one or more magnets arranged on the rotor. In use, when the turbine is driven to rotate about the axis, the or each of the magnets on the turbine rotor rotate relative to the generator stator in order to generate electric power.

Turbine generator

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.
