LINEAR STEPPER ELECTROMAGNETIC MOTOR Russian patent published in 2009 - IPC H02K41/03 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electronics and can be used for making a machine with discrete translational unrestricted motion of the actuating element. The device contains a stator, which consists of a side member (2) and a bottom part (1). A winding (9) is put into a stator bore. The armature is composite and consists of a cylindrical part (3) and has disc-shaped part (4) on the side of the guide housing (6). Between the bottom part of the stator (1) and the cylindrical part of the armature (3) there is recoil spring (10). The actuating element (13) can be in form of a rope, flexible bar or wire, let through the axial channel of the armature through an opening in the guide housing (6) and the bottom part of the stator (1). Power articulation of the actuating element with the armature in the working stroke is provided by spring-loaded keying on cone-shaped elements (11), for example in form of locking pieces, opened by a releasing mechanism in form of a double-arm swivelling lever (5) during the working stroke, put into the cavity of the disc-shaped part of the armature (4) with one arm, and on locking members (11) by the second arm. The lever has a through-hole where the actuating element is put. Coaxiality of the armature and the stator is provided by guide pins (8).

EFFECT: simpler design with widening of operating capabilities and field of use.
