LINEAR ASYNCHRONOUS MOTOR Russian patent published in 2020 - IPC H02K41/25 H02K1/14 H02K3/28 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, particularly, to linear asynchronous motors. Linear asynchronous motor comprises inductor 1 with magnetic conductor made of separate transversely laminated cores, containing teeth 2, united by common yokes 3. Said cores laminated in transverse direction are arranged one after the other in lengthwise direction and interconnected by cores laminated in lengthwise direction. Teeth 4 of longitudinally laminated cores are inclined and enter slots of transversely laminated cores with multiphase winding, coils of which are divided into two parts. First part of coils 5 is placed on transversely laminated cores, and second part 7 – on longitudinally laminated cores. Said windings form longitudinal and transverse rows, wherein longitudinal rows of coils form identical orders of phases, and transverse rows of coils have up to the middle of row one, and after middle – opposite order of phases. Inclined teeth 4 of lengthwise laminated cores are joined by common yokes 8.

EFFECT: increase of traction force and increase of efficiency factor.
