ELECTROMAGNETIC VIBRATOR Russian patent published in 1999 - IPC

FIELD: electrical engineering, in particular, vibration instruments. SUBSTANCE: device has electromagnet and armature, which are designed as two identical mobile working members, which are spaced from one another. Each member is designed as pair of half rings which are made from ferromagnetic material and are connected by washers, which are made from non-magnetic material.
