ROTOR, REACTIVE SYNCHRONOUS MACHINE AND ROTOR MANUFACTURING METHOD Russian patent published in 2019 - IPC H02K1/24 H02K19/14 H02K15/02 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electric engineering, in particular to the rotor of the reactive synchronous machine. Rotor contains a cylindrical magnetic-soft element equipped with recesses for formation of barriers for magnetic flow. Each of the flow barriers passes essentially arc-like, symmetrical to rotor pole segment axis, and is separated from other barriers by means of one or more partitions. Passage of separate partitions forms closed line dividing rotor in radial direction into inner and outer areas of rotor. Barriers for flow of inner and outer regions are filled with different fillers. One or more barriers of inner rotor area are filled with air or non-electroconductive and non-magnetically conductive filler, and one or several barriers of external area of rotor are filled with electroconductive and non-magnetically conductive filler. On the rotor end surfaces there are one or several short-circuited rings short-circuiting preferably at least two of the rotor outer area flow barriers.

EFFECT: technical result is improvement of start characteristics.
