(JP10285890-A)      The generator comprises an inner cylindrical permanent magnet rotor (1) disposed integrally with a center shaft (2) through driving vanes (3) and permitting the passage of a natural energy medium (4) for reducing the weight of the generator.    There is an outer cylindrical stator (10) so disposed as to keep a predetermined clearance (12) from the outer peripheral wall of the permanent magnet rotor through a bearing member (11) supporting the centre shaft, and having a stator winding (16) at a conductor fitting portion (13).    ADVANTAGE -   Is capable of generating power even by low natural energy. When natural energy is hydraulic power, the generator is suitable for use at camp sites by dipping it into rivers or sea.
