Abstract
A linear drive for pigmentation devices, comprising a stator, an air gap which is provided in the stator and is formed so as to be offset in a defined manner, an electric coil within the stator, said coil being designed to produce a concentration of the magnetic flux in the air gap as a result of the coil being energized, an armature which is designed to carry out sliding axial movements in the stator, and a permanent magnet which is captively connected to the armature.
