WebAug 25, 2016 · Voice coil actuators are a type of direct drive mechanism that provides extremely precise positioning over small displacements. Like linear motors, they work on the principle of a permanent magnet field and a coil winding. When a current is applied to the coil, a force is generated. This force, known as the Lorentz force, is determined by the ... Web=0) and a voice coil shift inwards to symmetry point x sym (x ac≈6mm) =1.6 mm is recommended.
