ELECTRIC GENERATOR SET ASSEMBLED OF GENERATOR AND PISTON-TYPE INTERNAL-COMBUSTION ENGINE USED AS ITS DRIVE Russian patent published in 2005 - IPC

FIELD: electric generator sets.

SUBSTANCE: proposed electric generator set has generator driven by piston-type internal-combustion engine, for instance, synchronous generator and diesel engine; it has permanent magnets for generator excitation disposed on generator rotor in pole areas and armature winding accommodated in stator. Pole areas of rotor are provided with axial intake pockets open on at least one end whose cylindrical peripheral wall is abutting against stator-to-rotor air gap. Each of permanent magnets disposed in pole areas is formed by plurality of magnetic components mounted close to each another in peripheral direction inside intake pockets. The latter are elongated in peripheral direction either side beyond respective last magnetic component to form free space.

EFFECT: ability of preventing demagnetization of extreme magnetic components caused by short circuits.
