SYNCHRONOUS RELUCTANCE MACHINE Russian patent published in 2017 - IPC H02K19/06 H02K1/20 

FIELD: electricity.

SUBSTANCE: machine comprises a stator with a winding stowed in the stator grooves, a rotor installed with a gap with respect to the stator rotatable relative to it and comprising alternating radially magnetic layers and magnetic flux barriers, each barrier having, at least, one peripheral end extending to the peripheral surface of the rotor, and the angular pitch of the peripheral ends decreases in a circumferential direction from the peripheral ends of the outer barriers to the peripheral ends of the deepest internal barriers with, at least, three peripheral ends consecutive in the circumferential direction, at least, two of which are the ends of the inner barrier. In a synchronous reluctance machine comprising a stator with a winding stacked in the stator grooves, a rotor installed with a gap with respect to the stator rotatable with respect to it and comprising alternating radially magnetic layers and barriers for magnetic flux. This gap is increased by 15-400% between the surface of the outermost magnetically conductive layer and the stator as compared to other parts of the gap.

EFFECT: improving the energy parameters of the reluctance machine, increasing the power factor, efficiency and specific power with the same number of barriers for magnetic flux.
