Embodiment Construction
[0028] Figure 1a Shown will vibrate device 2 (see figure 2 An exemplary embodiment of an energy harvester 1 that converts vibratory motion of ) into electrical energy. The energy harvester 1 comprises a pendulum 3 pivotably attached to a vibration device 2, a motion limiter 4 arranged to limit the pivotal movement of the pendulum 3 during movement of the vibration device 2, and a generator connected to the pendulum 3 5 (see Figure 1b ). A generator 5 is arranged to convert the pivotal movement of the pendulum 3 into electrical energy. The oscillating motion of the oscillating device 2 has an operating frequency, and the pendulum 3 has a natural frequency different from the operating frequency of the oscillating device 2 . The movement limiter 4 consists of a first blocking element 6 arranged on one side of the pendulum 3 and a second blocking element 7 arranged on the other side of the pendulum 3 . The energy harvester 1 has a first spring element 8 with a first end 9 a...
