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

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to linear step motors for discrete electric drive. Linear electric motor consists of upper magnetizing pole 1 containing non-magnetic inserts 3, 4, 5, and lower magnetizing pole 2 with non-magnetic frame 6 installed on them, in which there is magnetizing winding 7, insulated from housing 8 insulation tape 9. In order to install magnetizing winding 7 inside housing 8, top cover 10 is fixed, which is fixed with the help of screw 11, and lower cover 12 fixed by screw 13. Anchor 14 extending through top cover 10 is secured inside upper magnetizing pole 1 by means of upper non-magnetic plain bearing 15 and lower non-magnetic plain bearing 16. Between the upper non-magnetic friction bearing 15 and non-magnetic bushing 17 there is return spring 18.

EFFECT: higher efficiency and traction force, improved weight and dimensions.
