LINEAR ELECTROMAGNETIC MOTOR Russian patent published in 2010 - IPC H02K33/02 H01F7/16 

FIELD: electrical engineering.

SUBSTANCE: proposed motor incorporates cylindrical stator 1 accommodating coil 2 and armature 3 representing cylinder 4 with disk section 5. Guide case 6 made from ferromagnetic material adjoins the stator, case cross section being smaller than that of stator. Said motor comprises also guide case cover 7, plain bearings 8 and 9, return spring 10 and damping washer 11. Guide case top part adjoining cover 7 has inner circular ledge that fairs with armature disk section side surface by its diametre. Said inner circular ledge is connected via technological gap A with said armature disk section side surface to allow magnetic flux passage and armature retention at initial stage of its travel.

EFFECT: higher stabilisation of impact power.
