Document Type and Number:
Japanese Patent JP4212336
Kind Code:
B2
Abstract:
A synchronous machine (50) is disclosed comprising a rotor (54) coupled to a rotor cooling system ; a stator (52) around the rotor (54) and separated from the rotor (54) by an annular gap (57) between the rotor (54) and an inner surface of the stator (52) , wherein the annular gap (57) has a variable thickness along a length of the gap (57), and a stator ventilation system (82) independent of the rotor cooling system, wherein the stator ventilation system forces (82) cooling gases through the annular gap (57).
