REACTIVE SYNCHRONOUS ROTOR WITH RECESS FOR REDUCING VOLTAGES Russian patent published in 2018 - IPC H02K15/02 H02K1/24 H01F1/28 H02K29/06 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering. In the reactive synchronous rotor, a recess (6, 42) is formed in each magnetic flux passage portion (24) in the corresponding half (32) of the axis d to reduce the voltage, so that a partial flow section (36, 37) is formed on each side of the respective half (32) of the d-axis in the respective magnetic flux passage portion (24) in each case. Sum in each case of the smallest cross section of both the partial flux passage portions (36, 37) is substantially greater than or equal to the smallest, perpendicular to the respective half (32) of the d-axis of the cross-sectional area of the partial flux passage (36, 37) in the radial direction above the recess, so that no magnetic damage is caused by the recess (6, 42).

EFFECT: technical result is in simplification of the rotor mounting, in particular, by interference fit, and sufficient stability must be given.
