SYNCHRONOUS RELUCTANCE GENERATOR OF OFF-LINE POWER INSTALLATION AND METHOD FOR CONTROLLING IT Russian patent published in 2004 - IPC

FIELD: electrical engineering; on-board mains power supplies for motor-cars, tractors, cross-country vehicles, and the like.

SUBSTANCE: proposed synchronous reluctance generator has synchronous reluctance machine carrying multiphase running (power) winding, multiphase rectifier circuit, and storage battery. Its stator slots accommodate full-pitch auxiliary field windings and their magnetic axes are uniformly distributed along air gap and form multiphase symmetrical magnetic system. These field windings are connected to outputs of controlled exciters whose first control inputs are connected to field current setting source and second inputs, to output of generator rotor position sensor. Method for controlling this generator includes generation of magnetic flux over rotor longitudinal magnetic axis for which purpose current pulses are alternately passed from controlled exciters through auxiliary field windings of phases whose turns are disposed opposite interpole gaps of rotor depending on signal arriving from rotor position sensor output.

EFFECT: enhanced reliability of generator and simplified mechanical design of its rotor.
