ELECTROMAGNETIC DRIVE MECHANISM (ALTERNATIVES) Russian patent published in 2005 - IPC

FIELD: electromechanical engineering; vibrators and vibratory drives.

SUBSTANCE: device built to first design alternate has electromagnets symmetrically installed on different ends of bedplate, their armatures being rigidly coupled with operating elements and flexible members. Multipole annular electromagnets with flexible member installed in center of each of them are used for the purpose. One end of mentioned flexible member is rigidly fixed on electromagnet stator and its other end, on armature. Each electromagnet armature is made in the form of single plate; operating element in the form of rod is passed from top armature through center of flexible members, holes in stators, bedplate, and bottom armature; operating element running from bottom armature is made in the form of three shafts symmetrically disposed over circumference. Device built to second design alternate has electromagnet whose armature is rigidly coupled with operating element in the form of rod, and flexible member. Electromagnet is, essentially, multipole annular structure with flexible member installed in its center. One end of mentioned flexible member is rigidly fixed on stator and other one, on armature built in the form of single plate.

EFFECT: enlarged functional capabilities.
