Single-phase synchronous machine

摘要

A resilient structure for mounting the stator component of a synchronous electrical machine on its baseplate includes a plurality of spring brackets interconnecting respective points of attachment on the periphery of the stator component with the baseplate and which extend in radial planes as related to the stator axis. Each spring bracket includes at least one leaf spring the ends of which are held in spring retainers incorporating ribs disposed in the plane of the spring flexure. The ribs at opposite ends of the spring are rigidly fixed respectively to the stator and baseplate and the one or more leaf springs utilized in each mounting bracket are statically stressed only in tension by the weight of the stator component and are subjected to a dynamic bending stress in response to torsional vibrations occurring in the stator and which are absorbed by the springs which are softer in the peripheral direction than in the radial and axial directions. The spring bracket type of mounting structure is equally applicable to synchronous machines wherein the rotor turns on a horizontal axis as well as to those wherein the rotor turns on a vertical axis.
