ELECTROMAGNETIC DRIVE Russian patent published in 2018 - IPC H02K21/14 H02K1/14 H02K1/27 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to electromagnetic drives of direct current for transmission of angular displacements, and can be used to create on-off electromagnetic relays or devices with rotation of movable element to some limited angle and back with two stable states. Electromagnetic driver contains a stater and a tongue. Stater is made of casing, winding and two cylindrical sectors – poles located opposite each other and having a base at the opposite ends in the form of sector connected to casing. Tongue is mounted inside the stater and consists of constant magnet with radial intensity of magnetization and two patch pieces, and between the cylindrical sectors – poles of stater and patch pieces two radial working air gaps are formed. Stater, casing, winding and tongue axes coincide.

EFFECT: technical result is an increase in rotation angle of tongue, an increase in tractive effort torque, an increase in resistance to external fields and to impacts in the initial and activated states.
