POWER GENERATOR ASSEMBLY OF DRIVE ENGINE AND GENERATOR Russian patent published in 2005 - IPC

FIELD: electrical engineering; engine-generator sets.

SUBSTANCE: proposed power generator assembly has drive engine such as diesel engine and synchronous generator. The latter has fixed armature winding and rotor permanent magnets designed for generator excitation. Generator rotor is, essentially, external rotor that forms diesel engine flywheel and generator stator disposed inside rotor carries armature winding. Rotor is installed on fan impeller flanged, in its turn, to drive engine crankshaft on its butt end. Stator is assembled of stack of steel stampings that carries armature winding and is secured at several points over circumference to inner ring of generator frame cover provided on outlet end by means of stator screws passed through holes in stator stack that also function to brace together its stampings. Rotor has stack of steel stampings carrying permanent magnets designed to built up revolving magnetic field and is screwed at several points over circumference to fan impeller by means of screws passed through holes in its stack which also brace together its stampings.

EFFECT: reduced mass and space requirement of generator, simplified design, eliminated danger of crankshaft sag, facilitated cooling, provision for multiple reuse of assembly components.
