GENERATOR UNIT Russian patent published in 1998 - IPC

FIELD: electrical engineering; permanent- magnet generators with voltage regulators for internal- combustion engines. SUBSTANCE: generator unit has stator with three-phase winding 1 on crankcase cover 2, flywheel 3 with permanent magnets 4 on annular rotor core and with fan blades 5. Flywheel is mounted on extension of shaft coupled with drive engine. Ducts inclined relative to shaft axis are provided between blades 5 of flywheel 3. Provided in external flywheel housing, on its peripheral section, is port to receive throughput voltage regulator with cooler 11. Throughput voltage regulator has rectifier connected into Larionov's bridge circuit and pulsed voltage stabilizer. Peripheral section of flywheel housing with port is inclined and offset relative to shaft axis so that cooler pins are arranged in air stream running from cooling blades of flywheel 3 that cools down drive engine. EFFECT: improved efficiency and other specific characteristics, improved reliability of generator unit and load circuit due to improved stability of output voltage. 5 cl, 3 dwg
