FIELD: instrument engineering.
SUBSTANCE: device can be used for forming parametric oscillations during process of production items based on usage of vibrations. Ferromagnetic axis is introduced into case of electromagnetic vibrator, onto which axis the coils are rigidly mounted to alternate with cores introduced additionally. Cores form stator of linear asynchronous engine. Armature of engine is made to be hollow; it embraces axis and is disposed for movement at the axis between the case and coils. Longitudinal grooves are made in the body of armature where pole tips are placed.
EFFECT: widened operational capabilities.
