Abstract
The magnetic circuit (6) of the stator is suspended from resilient suspension bars (26) which are welded both to floating stiffening rings (30) that are firmly mounted on the magnetic circuit, and to some of the stiffening rings (20) of the outer sheath (18). Other casing stiffening rings (22) have openings to allow the suspension bars to pass freely therethrough, and are equipped with stops to limit rotation of the stator in the event of an electrical fault. There are thus two paths for transmitting force between the magnetic circuit and its surrounding sheath, one of which can be optimized for damping the vibrations of normal use, while the other can be optimized for avoiding damage under fault conditions.
