ROTARY ELECTROMAGNET Russian patent published in 2019 - IPC H01F7/14 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, to rotary electromagnets, and can be used in electromechanisms, in pneumatic and hydraulic systems, where low movements and high forces, as well as stability of armature movement force are required. Rotary electromagnet has magnetic conductor 1, having poles 2 in the form of sectors, discs of rotor 3 and discs of stator 4 in the form of sectors, winding 5, non-magnetic bushing 6, shaft 7, housing 8, bearings together with covers 9, reverse spring 10, stop 11. Housing 8 is rigidly connected to magnetic conductor 1. Rotor 3 has set of sectors from ferromagnetic and nonmagnetic materials, they are mechanically connected with bushing 6 and with shaft 9. Stator 4 comprises a set of sectors from ferromagnetic and nonmagnetic materials. Thickness of discs 3, 4 is twice more than height of projections on magnetic conductor.

EFFECT: technical result consists in increase of force at maintaining dimensions and consumed power, as well as stability of force on rotor turning angle.
