LINEAR DRIVE WITH CORE AND ARMATURE WITH PERMANENT MAGNETS (VERSIONS) Russian patent published in 2009 - IPC H02K33/16 

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering and can be used in a linear drive. The drive has at least one exciting winding (3) for generating alternating magnetic flux with a magnetic conductor, consisting of a core (5) and magnet frame (6), as well as an armature (8) with two permanent magnets (9a, 9b), brought into oscillatory motion between parts of the magnetic conductor by magnetic field. Width (b_j) of the shaft (5a-5c, 6a-6c) of magnetic conductor (5, 6) and the distance (b_w) between them should have a certain value, which depends on the length (b_pm) of magnets (9a, 9b) in the axial direction.

EFFECT: easier manufacture.
