SYNCHRONOUS ELECTROMAGNETIC MOTOR OF BACK-AND-FORTH MOVEMENT Russian patent published in 2013 - IPC H02K33/12 F16F7/104 

FIELD: electricity.

SUBSTANCE: motor of back-and-forth movement includes housing, magnetic conductor with coils of forward and backward motion, guide pipe with striker for transfer of impact action on working tool, which is arranged in it. Elastic element is mechanically connected to intermediate body, the weight of which is more than striker weight. Intermediate body has thrust surface that faces the striker side. Additional elastic element interacting through thrust surface with intermediate body is installed between intermediate body and striker. Additional elastic element is installed with possibility of interacting through the formed thrust surface with intermediate body with elastic element and provides mode of free vibrations of mechanical system.

EFFECT: improving reliability owing to preventing electromagnetic motor assemblies against dynamic loads resulting from deviations from working modes disturbing the periodicity of its operation.
