摘要: The invention relates to a pod propulsion unit of a ship. The pod propulsion unit comprises a pod housing (1) arranged at least partly below a hull (2) of the ship, an electric propeller motor (3) within a motor gondola (4) of the pod housing (1), an annular gap (8) between a rotor (6) and a stator (7) of the electric propeller motor (3), and gas channels (9) extending through the rotor (6), a closed cooling gas circuit (10), and a fan (11) for circulating gas in the closed cooling gas circuit (10). The closed cooling gas circuit (10) comprising a feeding duct (27) extending between the return duct (28) and the first motor end face (30) of the electrical propeller motor (3), and a return duct (28) extending between the feeding duct (27) and the opposite second motor end face (31) of the electrical propeller motor (3).
