HIGH-SPEED GENERATOR BASED ON DOUBLE-POLE MACHINE WITH DUAL VOLTAGE SYSTEM, INTERMEDIATE ROTOR AND CAPACITOR-TYPE SELF-EXCITATION Russian patent published in 2013 - IPC H02K17/00 H02K1/06 

FIELD: electricity.

SUBSTANCE: high-speed generator based on double-pole machine with dual voltage system contains stator (1), intermediate solid rotor (2) and phase-wound rotor (3). Windings of stator (1) and phase-wound rotor (2) are connected in series and in parallel and excitation capacitors (11), load (12) and reactive power static compensator (13) are connected to it. Intermediate rotor (2) has two squirrel-cage windings (14) and (15) which bars are laid into slots and closed at rotor edges by two cage rings (16). Shaft of phase-wound rotor (3) and shaft of intermediate rotor (2) are connected by tooth gear with drive ration equal to two. The gear consists of gear-wheel (5) fixed at the shaft of phase-wound rotor (3) linked with tooth gear wheel (6) located at gear axis (7). At the other end of axis (7) there is gear-wheel linked to wheel (9) fixed at intermediate rotor (2). The axis (7) can be offset manually or automatically and mechanical bond between shafts can be broken when steady conditions with capacitor-type excitation are reached. Generator is driven by combustion engine (10).

EFFECT: providing capacitor-type self-excitation during operation in autonomous mode and reducing voltage distortions at connection of asymmetrical load.
