Abstract
A horizontal-axis electrical machine has an built-in stator concentrically surrounded by a number of parallel retaining rings that spaced apart from one another in the axial direction and are connected on their outer circumference on opposing sides in each case by means of retaining structures to a base frame which extends in the axial direction. A horizontally acting spring, which has the form of a perpendicular, longitudinal plate, is fixed on the one hand with its ends to the associated retaining ring, and is firmly connected on the other hand with its freely flexible central part to the base frame by means of connecting elements, being provided within each of the retaining structures. Improved oscillation isolation between the built-in stator and the base frame is achieved in such an electrical machine by vertically acting spring elements disposed between the ends of the spring and the associated retaining ring.
