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

Abstract RU 2496215 C1

FIELD: electricity.

SUBSTANCE: motor includes non-magnetic housing made as an integral part of working tool shank fastening device, magnetic conductor with coils of forth and back movement, which are located inside non-magnetic housing; striker is located inside guide bushing so that it can interact with shank of working tool and spring-loaded buffer. On the side opposite to buffer, shank fastening device is adjacent to magnetic conductor and rigidly attached to it and made in the form of hollow cylinder, inside which a damping core spring-loaded towards striker with elastic element is installed with possibility of axial movement. In centre of damping core there is a through hole, the diameter of which provides free entering of shank projecting relative to core towards striker at distance x. In initial position, distance x between end surfaces of damping core, which face the striker, and the shank is equal to amplitude of vibrations of the latter.

EFFECT: increasing productivity at simultaneous improvement of reliability at treatment of material with different degrees of hardness or at loss of contact of working tool with treated medium.
