SMALL SIZE VIBRATION MOTOR ENERGY NONUTILITY GENERATION AND THE METHOD

摘要

PURPOSE: An apparatus for generating the energy independent power of a small-sized vibrating motor is provided to reduce energy consumption by generating and charging periodic electrical energy. CONSTITUTION: A small-sized vibrating motor comprises an actuator(100), an independent energy plant(200), and an energy charging element(300). The actuator generates a reaction force of magnetism by changing power applied from the outside to a magnetic field. The independent energy plant generates energy by using a piezoelectric layer(220) of a piezoelectric material. The independent energy plant comprises a second magnetic force generation part(210) installed to be magnetically contiguous to a first magnetic force generation part, the piezoelectric layer, and an elastic member(230) arranged between the first magnetic force generation part and the second magnetic force generation part. The energy charging element charges energy by regenerating vibration to the energy.
