DEVICE TO REGULATE ARMATURE TRAVEL IN REVERSIBLE LINEAR DRIVE Russian patent published in 2009 - IPC H02K33/16 F04B35/04 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering and can be used to regulate armature stroke (H). Armature (8) of reversible linear drive (2) with excitation winding, makes liner oscillating motion, forced by excitation winding magnetic field, in axial direction with preset stroke (H). Proposed device comprises appropriate means to determine current armature position (x), appliance to measure current values of excitation winding current (I_ist) and means to set excitation winding current (I_soll) to allow feeding to armature the amount of energy required to produce oscillation amplitude (+L₁, -L₂), during armature half-wave stroke, corresponding to preset armature stroke (H).

EFFECT: higher accuracy of adjustment.
