LINEAR ELECTRIC MOTOR Russian patent published in 2019 - IPC H02K33/02 H02K1/34 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to linear electric motors. Linear electric motor comprises a stator consisting of a magnetic housing in which there is a magnetising coil creating a magnetic flux. Coil is installed on the non-magnetic frame. Electric motor includes an upper magnetic pole, the cross-section of which has the shape of a rectangular trapezium, an end magnetic pole and a lower magnetic pole having a recess in the form of a cylinder, as well as a nonmagnetic insert. Electric motor armature consists of an upper magnetic conductor having the shape of a truncated cone, a lower magnetic conductor, a non-magnetic bushing placed on a nonmagnetic core. Anchor is installed in stator by means of nonmagnetic carcass and non-magnetic insert serving as sliding bearings, and also return spring, washer and nut.

EFFECT: improvement of weight and size characteristics, increase of traction force, and also increase of efficiency factor.
