Abstract
A support structure is used to mount the stator of a rotating electrical machine (e.g. a motor or generator). The support structure includes a rigid external support frame (). To minimise the transmission of vibrations caused by stator electromagnetic forces into the external support frame (), at least one sandwich anti-vibration mount () is secured between the external support frame () and a part of the stator (). The mount () is oriented relative to the stator such that it experiences compression loading in a substantially tangential direction of the stator and radial shear loading in a substantially radial direction of the stator during operation of the rotating electrical machine. The sandwich anti-vibration mount () is pre-loaded with a pre-determined compression load substantially along its compression axis (Ac). The mount () has a high stiffness characteristic Kc for compression loading and a stiffness characteristic Krs for radial shear loading that is substantially zero, or even negative. The mount () will therefore restrain tangential deflection of the stator while still achieving a low-stiffness suspension in the radial direction.
