Abstract
An electrical power generating system (10) for generating alternating current in accordance with the invention includes a main generator (14) for generating the alternating current having a stator (22) and a rotor (24) and an excitor (12) for generating excitation current of the main generator having a stator (16) and a rotor (18) With the rotors being coaxial and driven by an input shaft (36); a cylindrical non-electrically conductive containment sleeve (70) mounted in surface contact with the coaxial rotors so that the rotors fit within the sleeve to provide support for the rotors against centrifugal acceleration and for containing coolant liquid inside the cylinder and an outside surface facing an inner cylindrical surface of the stator; and a coolant circuit (50) for circulating the coolant liquid to cool windings (30) of the main generator rotor and windings (42) of the excitor rotor, the coolant circuit including a first portion (52) through which flows the coolant liquid received from a coolant input (50) through the windings of the main generator rotor and a second portion (56) through which liquid coolant flows into contact with the windings of the excitor rotor with the containment sleeve preventing coolant from flowing radially outward into an air gap between the rotors and stators of the main generator and the excitor.
