SYNCHRONOUS GENERATOR Russian patent published in 2022 - IPC H02K21/12 H02K16/04 H02K3/28 H02K1/16 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular concerns the improvement of the design of a synchronous permanent magnet generator used in autonomous power supply systems. The synchronous generator contains a rotor, stator, stator windings, shaft, bearings, permanent magnets. The stator is made in the form of a ring and is divided into two annular parts, the inner and outer rings of the stator, made in the form of magnetic circuits with cores on which the three-phase windings of the inner and outer rings of the stator are wound. The stator windings are interconnected according to the “star” scheme at low voltage in the phases of the stator, and according to the “triangle” scheme at high voltage in the phases. The rotor is made in the form of a ring with permanent magnets fixed in it and is located between the inner and outer rings of the stator. The rotor rotates freely relative to the stationary stator and is driven by a shaft fixed in bearings.

EFFECT: optimization of the magnetic system of the generator, an increase in the power of the generator and an increase in its efficiency, the organization of a three-phase power generation system, voltage stabilization by switching the circuits of the stator windings from a star to a triangle and back depending on the load power and rotor speed, avoiding the effect of "sticking" of the rotor, reducing the specific metal consumption of the generator per unit of power.
