ELECTROMAGNET Russian patent published in 2009 - IPC H01F7/13 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, and more specifically to translational motion plunger electromagnets, and can be used in electric actuators, in pneumatic and hydraulic systems. The electromagnet has a magnetic core 1 with two cone-shaped tips 2, with ring lugs 3, hollow cylinders 4, 5, which are a set of rings made from ferromagnetic and non-magnetic materials and mechanically linked in turns to an armature 6, with ring lugs and to a magnetic core 1 with a pull rod 7, non-magnetic bushing 8, winding 9, housing 10 and recoil spring 11.

EFFECT: electromagnetic strength with retention of dimensions and power input, as well as stable force on movement of the armature.
