HIGH-SPEED SWITCHED RELUCTANCE ELECTRIC MACHINE Russian patent published in 2022 - IPC H02K19/06 H02K1/22 H02K1/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular, to designs of high-speed switched reluctance electric machines, and can be used in the development of various drives of high-speed electric machines. Switched reluctance electric machine comprises a stator consisting of a magnetic core of the stator with six salient poles with stator excitation coils located thereon, a shaft, whereon a non-salient-pole rotor is installed. In the four interpolar areas of the non-salient-pole rotor, longitudinal through holes of the same size are made, the cross section whereof constitutes a circumference, arranged in two layers. The longitudinal through holes located in one layer are equidistant from the axis of rotation of the non-salient-pole rotor, and the amount of holes in the layer closest to the axis of rotation of the non-salient-pole rotor is less by one than the amount of through longitudinal holes in the layer closest to the surface of the non-salient-pole rotor. The distances between adjacent holes located in the same layer and in the same interpolar area are the same, and the width of the salient pole of the stator is greater than the distance between the interpolar areas of the non-salient-pole rotor.

EFFECT: increase in the characteristics of energy efficiency due to the significant difference in the magnetic resistances of the rotor in various radial directions and due to the provided near-linear flux linkage characteristic in the excitation coils connected to the phase of the electric machine, as well as increase in the reliability due to the distribution of the non-magnetic and non-conductive material in several areas of the interpolar space of the rotor so that the strong magnetically conductive material of the rotor, the thickness whereof is sufficient to minimise the deformation of the rotor from the impact of centrifugal forces during rotation, is located around the non-magnetic and non-conductive material.
