Power generating installation that compises a drive engine and a generator

Power generator unit composed of a drive motor and a generator, particularly a diesel engine and a synchronous generator, with a stationary rotor winding (28) and permanent magnets (35) for excitation of the generator, where its rotor (29), as an external rotor, forms the flywheel of the diesel engine, and where its stator (11) carries the rotor winding (28) and is arranged within the rotor, characterized in that

• the rotor (29) is built onto a fan wheel (2) that in turn is flanged onto the crankshaft (1) of the drive motor, at its face;
• that the stator (11) is structured as a package of iron sheet metal, which bears the rotor winding (28) and is screwed on multiple times at the circumference of an inside ring (10) of a generator housing lid (9) provided at the outflow side, by means of stator screws (17) that are passed through bores in its sheet-metal package and secure the sheet-metal package together;
• that the rotor (29) is structured as a package of iron sheet metal, which bears the permanent magnets (35) to generate a rotating magnetic field, and is screwed on multiple times at the circumference of the fan wheel (2), by means of clamping screws (30) that are passed through bores in its sheet-metal package and secure the sheet-metal package together.
