FIELD: electricity.
SUBSTANCE: linear drive has at least one excitation winding with core for development of alternating magnetic field. Anchor (8) has a magnetic medium (12), with at least two permanent, preferably, lamellar magnets (9a, 9b), which is put into reciprocal oscillating motion by magnetic field of excitation winding. To prevent vortex currents in magnetic medium (12), at least those its parts that enter magnetic field limited with polar tips of core and excitation winding. or those that lie in this field, are made of electrically nonconducting material. Magnetic elements (9a, 9b) may be closed with ferromagnetic coats.
EFFECT: reduction of braking force.
