LINEAR ELECTRIC MOTOR Russian patent published in 2015 - IPC H02K41/02 

FIELD: electricity.

SUBSTANCE: invention is related to electrical machines, in particular to linear step motors and may be used in a discreet electric drive. Linear electric motor comprises a stator consisting of a magnetic body with magnetising coils installed between the left and right magnet poles; interpoles are fixed by non-magnet inserts at the thread. Between the right magnet pole of one coil and the left magnet pole of the other coil there are non-magnet rings fixed by pins. The butt end magnet pole is fixed to the magnetic body by a bolt. Armature of the linear electric motor consists of magnet and non-magnet rings put on to the non-magnet bar in alternating sequence. Cross-section for butt ends of the right magnet poles and left part of interpoles as well as for butt end pole has a shape of irregular trapezoid. Cross-section for the left magnet poles and right part of the interpole has a shape of right triangle. Cross-section for the left butt end of magnet armature rings has a shape of irregular rectangle while the same of the right butt ends has a shape of right triangle.

EFFECT: increasing effort at the armature of a linear electric motor under load.
