Solenoid magnet has stator and excitation coil, with armature including permanent magnet polarized at right angles to direction of motion of armature

摘要

The solenoid magnet includes at least one magnet system comprising a stator and an excitation coil, for generating a magnetic flux in the moving direction of an armature to act on a transfer member. The armature includes a permanent magnet device (44) polarized at right angles to the direction of motion of the armature. The armature may be arranged between two magnetically isolated magnet systems (2,3).
