A dynamoelectric machine includes a rotor and a stator surrounding the rotor. The stator includes a plurality of windings arranged in a main portion adjacent the rotor and terminating in a plurality of inner and outer end windings extending outwardly from the main portion. An end winding support assembly includes at least one support ring for the plurality of end windings and a respective adjustable bias member between the at least one support ring and each adjacent end winding to provide an adjustable separation bias between the at least one support ring and each adjacent end winding.

A flexible, gas tight electrical coupling for a gas cooled electrodynamic system such as an electrical generator includes a first connector element that is in communication with a first combined coolant and electrical path and has a first passage defined therein for a coolant, a second connector element that is in communication with a second combined coolant and electrical path and has a second passage defined therein for the coolant, a flexible tube for communicating the first passage in the first connector element with the second passage in the second connector element, and an electrical connection for electrically connecting the first connector element to the second connector element. According to one aspect of the invention, the electrical connection is external to the flexible tube, resulting in cost savings and other advantages when compared to an internal electrical connection. According to a second aspect of the invention, an outside of the flexible tube is sealed to the first and second connector elements to effectively guard against leakage of the coolant.

A rotor for an electromagnetic energy conversion device, which rotor includes a core composed of a stack of thin plates, is clamped between two end plates by means of a plurality of end clamping fingers. Each clamping finger is initially mounted on a respective end plate and is then pressed against the core by a clamping force applied via the end plates.
