LINEAR REVERSIBLE VIBRATION MOTOR Russian patent published in 2019 - IPC H02N2/02 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment and can be used as the actuating element for precision movements in optical-mechanical instruments, in technological equipment for microelectronics, in the automatic guidance systems, in mechanical scanning devices and piezo drives. Linear reversing vibration motor contains the driven element, a vibrator made on the basis of a piezoelectric element, which one end rests against the holder through the damping gasket, and the other end rigidly rests against contacting with the driven element nozzle. Nozzle is the reversible contact gripper, made in the form of a plate with covering the driven member hole. Holder is mounted on the vibration motor housing. Reversible contact gripper touches the driven element with the hole upper or lower edge. By one end it is rigidly fixed to the rod. Through the covering hole the driven element is passed. Driven element movement amount is determined from the relationship: X=(l-a)⋅cosα, where a=ΔX/sin α is the reversible contact gripper stroke to contact with the driven element surface, X is the driven element movement amount, l is the piezoelectric element stroke value, ΔX is the size of the gap between the driven element and the reversible contact gripper, α is the angle between the driven element and the piezoelectric element axes of symmetry.

EFFECT: technical result consists in the reverse motion possibility implementation in the vibration motor design.
