Mounting arrangement for an electrical machine

摘要

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.

1. A mounting arrangement for locating a stator within a casing of a rotating machine, comprising:
at least one mounting plate adapted to engage with the stator and the casing, the mounting plate having a series of discrete apertures therein that each include a radial portion and a tangential portion, the apertures extending through the mounting plate and being arranged to provide a convoluted path to impede the transmission of forces through the mounting plate, each of the apertures defining at least one of the following configurations: 1) the radial and tangential portions intersect at substantially a 90 degree angle, and 2) the tangential portion intersects an end of the radial portion and another tangential portion intersects an opposing end of the radial portion to define a Z-shaped configuration.
