Abstract

PURPOSE:To directly drive a generator without increasing the entire length and the weight of a marine main engine by mounting a generator rotor at the rear side of a flywheel provided between the main engine and a propeller, and forming a generator oppositely to the state of a hull side. CONSTITUTION:A flywheel 2 is mounted on a main shaft 2 for coupling a marine engine 9 with a propeller, and the coil member of a generator rotor 1a is secured to the outer periphery of the rear side (propeller side) of the flywheel 2 to be rotated integrally with the flywheel 2. A generator stator 1b is mounted on the inner surface of a casing 11 opposed to the rotor 1a to form a generator 1. Thus, since a drive shaft system for driving the generator is not necessary, the entire length and the weight of the main engine 9 are not increased, and the generator 1 which can be driven directly by the main engine 9 can be obtained.
