Description

Curved segment permanent magnet actuator

The present invention relates to a curved segment permanent magnet actuator, in particular to an actuator structure capable of generating a stroke change, thereby utilizing a magnetic attraction principle to cause a magnetic block to attract a magnetic member to cause bending deformation of the elastic plastic plate.

Those skilled in the art of automatic control of machinery, by means of air pressure or hydraulic cylinders, actuate the displacement of an object or press and fix the object. However, the compressor that drives the pneumatic cylinder with gas and hydraulic pressure is inefficient. Compared with gas and hydraulic pressure as the power source, the energy consumed by the power source is relatively low; therefore, the electric actuator has been In many applications, an electric motor is used instead of a pneumatic cylinder, and the rotation of the electric motor is converted into a linear motion, so that the output shaft linearly reciprocates.

However, with the evolution of technology, the volume requirements of equipment are mainly light and short, and the driving equipments of various thin 3C products are required to have basic functions such as low noise, large driving force, good heat dissipation and precise positioning capability, such as: micro motor. And micro fans, etc., have recently been applied to piezoelectric actuators, which have the advantages of low voltage, no noise interference, small volume, fast response, less heat generation, good precision, high conversion efficiency, and easy control. . The piezoelectric actuator operates on the principle of generating an energy wave by inputting electric energy, and thereby deforming the metal disk of the piezoelectric actuator, thereby generating an urging force.
